Thanks WWK! Saves me a headache 🤕 hassle. I have a 2013, Avalanche, I got a good scan tool and found a misfire on #6.. the spark plug wire was broken and someone put the wrong plug In. New wires, plug and coil helped.. I’m getting a P015D, P0446, P0451.. Evap and a Fuel Pressure Sensor error. How do I fix this problem? What parts do I need and do I need a replacement Evap line?

Respect from northern Ontario Canada. You saved my 6 ltr V8 HD I was going to change the knock sensor then if that did not work I was thinking it was lifters and I may need to also change the cam. I was going to try a knock set delete. Here the entire time it was the muffler guys not fixing the issue. I got under it and made the repair after watching. You saved my thousands. Your a rock 🌟. Respect from northern Ontario Canada

Thank you for posting this video. This is EXACTLY what is happening with my GMC Sierra (same bolt, even). Your video was very helpful in understanding what was going on and I appreciate your followup video on how to do the repair.

And once again. You have not failed me! A lot of the other mechanic guys could learn a lot by watching you. You get straight to the point. You don’t stretch the video. You give a brief history. Some comparisons and then your thought process. That information alone is priceless! Thank you again sir 🙏🫡🥃

As soon as you started it I knew exactly what it was. The sound was the key here. That is no lifter. You can hear the exhaust escaping from around the manifold. Very distinct sound compared to a valve or lifter tick which is more metallic in nature as well as internal and sometimes muffled. This is external by nature. Either a broken stud/studs or cracked manifold itself. Like he said very common. Especially northern exposure vehicles due to snow and salt emulsion. Death by CORROSION. Truthfully I have repaired only a dozen or so lifter jobs on these due to the fact that they were caught early but if left alone you are looking at cam and lifter replacement. Once it starts it just progresses from there to total carnage of the cam. It’s good that this man is around for him. Good ear as well as knowledgeable about these engines. But most importantly EXPERIENCED. Just because they went to school to learn how it works doesn’t meant they are experts. Experience is gained by years of working on them. Not a text book. Good example of old school vs new school. Very informative video. 👍

@@MercuryRisingFast that would be a rod bearing. Pull the oil pan and windage tray to inspect the rods. Look for up and down movement. Side to side is normal to a curtain degree but up and down is not good. If you find up and down then you may have a spun bearing. Depending on how long it has been doing that will determine whether or not you need just bearings or a tear down to replace rods. Put the vehicle up on lift and have it running. Listen to where the knocking is concentrated at. If it is down low you have a bad rod bearing or more. If further up towards the top of the engine near the heads you have piston slap from bad rod pin sleeve. If the later then a tear down is required to replace pistons and rods. Full lower end rebuild. That’s worst case scenario. But if just a spun bearing and no visible damage to the journals then bearing will fix the issue. If there is damage then the crank needs to come out and replaced if the damage can’t be cleaned up and smoothed out to spec. If can be cleaned and smoothed out oversized bearings will work. Need to spec the journals after smoothing with a micrometer so you get the correct size. That’s it in a nut shell. Good luck.

Actually worst case would be a new engine but nowadays engines can be had pretty cheep with low miles. Just getting it installed will cost you.

I stumbled on your previous video in regards to the ticking 5.3 that was related to the plug wire issue. At the time I had been chasing down a ticking noise with my wife's 2013 Yukon which I had just recently rebuilt the entire top end. DOD lifter had failed and ate the cam. Needless to say I was having flashbacks. While the new noise wasn't caused by a plug wire issue it did get me snooping around a bit more and I caught a glimpse of some soot at the manifold near the firewall. There were two exhaust manifold bolts that had either work their way loose or I had failed to fully tighten them. Snugged them down good and checked the rest. The engine is back to purring like a kitten. Crazy how something so simple is so easily missed. Thank you for the other video as it got me to look into it more and eventually got me headed in the right direction.

Domestic cars are designed to last just until the warranty goes out then they start failing. He had replaced 3 engines in Trail Blazers that month. We got a Toyota and man are we glad we did. As far as trucks are concerned they are all a crap shoot now. They charge you 60-90 grand and put a crap warranty on them. For as much money as they are selling them for you should have a warranty that goes to 200k miles IMO.

When looking for noises, it's handy to use a piece of tubing--large vacuum hose is good for this--you stick one end in (or close to) your ear, and then probe around to where the sounds becomes louder. It's an easy way to pinpoint the location of the sound. I have this motor, and I was able to track a light knocking noise to the . . . fuel pump, using this vacuum hose method.

I'm amazed these vids still pop up; these are known issues with LS for the last 20 years. Ticks are rarely ever lifters in the LS or cams (99 to 06/07). They are generally pushrods having drilled out the rocker arms or sheared off exhaust manifold bolts(almost always the very front or very rear bolts). Probably 90% of ticks in the Gen III motors. 08 and up add the DoD/AFM failures to those tick sources. This engine also seems to have a lot of piston slap(likely aluminum block, which transmits that sound better) but while annoying it's a non-issue.

That's a bingo with the exhaust leak. I bought a low mileage Chevy Tahoe from the auction claiming it had engine noise. Got it cheap. Upon examination discovered a major misdiagnosis. Two broken exhaust studs driver side rear. Took a stethoscope to the engine itself and it was quiet as a church mouse. Oil pressure good. long story short I bought a beautiful 2016 low mileage Chevy Tahoe for $3,000 at auction, replaced the two exhaust studs and the vehicle runs and drives perfect. Exhaust leaks are very common problem on L Series Chevrolet engines. Hope you all get a great steal yourselves out there, but make sure it is an exhaust leak because some 5.3's have lifter issues and they don't come out from the top either.

Ya gotta love these 5.3’s I have a 2000 LM7 5.3, I’ve had it 21 years. It’s got 207K on it and I just changed the plugs and wires. At 100K the plugs were in perfect condition and showed no wear.

And I’ll address that when it is needed. Unfortunately my truck will probably crumble into a dust pan before that happens. Gotta love the northeast…. Great videos 👍

Those ls are notorious for the front and rear bolts on the exhaust manifolds breaking off. I've been thru 3 spools of wire to date removing these for people.

I knew what it was before you started it. Mine does the same and I’m missing studs. I just put in those easy adapters on

4:20 BINGO!!!!!!!!!!!!! My rattling noise comes from the passenger rear area of the engine!!! Mine doesn't sound as loud as yours and it seems to go partially away after a couple of minutes. I just drove it over two hundred miles with no problem, but I think the noise is worse after the trip. Last year I had the exhaust manifold removed on that side because I saw that, three bolts where broken. It made no noise, however. I had the bolts and gasket replaced!!! Still, no noise. The noise actually Does sound like a few coils are ticking! Thank you for this video. I really thought it was the rear main bearing, $$$, but I thought, why would it be from only one side? Well, just a thought checked it again. It's not the manifold and not the bearing. It seems to ch a new location. Now it seems like it is in the area of the right rear passenger area under the car. I ran it for one minute and it was very loud and then it stopped completely. I turned it off and restarted it and it came back quieter. I think something could be loose in thr exhaust the tightens up when it heats up. Any thoughts on that? Most mechanics just throw parts at the problem because Thinking and troubleshooting is so much harder. Case in point. The directional signal and emergency flasher don't work. Change the flasher, right? Wrong! The fuse was good, but it had corrosion on it. I scrapped it off and they came back on. Another case in point. The P4020 code for the cat came on and the computer wouldn't get the car ready for emissions. The problem was the need for a Drive Cycle after the battery had gone dead for three days and I installed a new one. Another case in point. The entire interior of my Tahoe would go electrically dead while driving. I mean, everything electrical was dead but the truck would still drive. When a mechanic had worked inside the dash, they didn't put everything back in its proper place. There is a small Black Box above your left shin that snaps into a galvanized bracket. It was just floating inside it and moving around and every time I made a hard left turn, the car would go dead and sometimes stay dead. When I made a sharp right turn, the power came back on. Something must be moving! I found the loose box and snapped it into the holder and the problem never returned.

that's way better than a lifter problem. I have the same issue on my 4.8. going to check it out when I get time. thanks!

Yea, that’s common. Ls exhaust manifold bolts are just too small diameter. They need changed before you hit 100k miles or they’re likely to start breaking in my experiences. Unless you throw some arps on. Another common “tick” is that crush gasket on the drivers side exhaust manifold (pretty sure it’s the driver side) , they go out around the same time the exhaust manifold bolts start going. If they start breaking, don’t take it to a shop and get got for about $2k cash. Throw the front end up on jack stands, remove the wheels and fender liners, and steering column section, (do the following work from the fender area) remove the headers. already have the new gaskets, bolts and thread locker, and spare nuts, something like 1/2” and 3/8”. Even if the bolts are not broke flush and stick out, go ahead and weld a nut on it, and run it out with a little patience, you’ll get everyone of them, with ease and no problems. When putting everything back together, do NOT put anti seize on the exhaust manifold bolts, they WILL back out after a couple months and cause another exhaust leak, instead use high strength or removable high strength loctite or vibratite. If you go arp, you should be sat for the life of the vehicle, if you go with gm or other brand, change them before you hit the next 100k miles and you won’t have to deal with this again (or before what ever mileage interval you just when they started breaking. Flux core welders do work for this repair too, just turn the wire speed down and heat up, put some heat in the weld

Fixed it 3 years with new seal and hasn’t done it since. I tried to find help from GM techs and they couldn’t even help me. New oil pick up seal and oil pan gasket and not another embarrassing drive through experience at Burger King since I did it

I build alot of these motors, ive never had the after market bolts break!

I believe more times than not I have seen people's "ticking" to be exhaust leaks. Otherwise... ignition issues, bad pulley bearings, intake leaks, a light tick sound from injectors and of course a loose spark plug (exhaust/system leak). More times than not it is repairable without major work.

I owned an 2002 Silverado with the 5.3L, and when my ticking issue arose, it was the catalytic converter. It was actually covered under warranty at a Chevrolet dealership. Not sure if GM ever issued any bulletins or recalls about the issue. I was actually surprised that I didn't have to pay anything.

Easy fix, part store sells a bracket just for this problem that bolts onto the back of the motor and tightens to the face of the exhaust manifold. Same thing will happen to the other side as well, they make a braket for that as well. Of course could you could go the expense route if u like, which if you have the 706 heads you will be doing anyways. Good luck!

Most common issue is if not lifters and after having sat is problems with exhaust manifold leaking! Very common issue with the ls, and dodge hemi's. Both my wifes yukon denali with the 6.2 ls and my dad's HD 2500 Silverado have this exact issue. The problem lies with the head being aluminum and the exhaust manifold being cast iron. The two different materials expand at different rates and causes flexing that break the bolts, or even crack the manifold.

I had ticking in my 63 Chevy Impala convertible 283 54 years ago I would adjust the valves and in no time it would start again ....Chevy has a history of ticking.

A few exhaust studs on my 97 f150 looked like rivets when I changed them out. They rusted out so bad I had to grind them down flush with the manifold to get the manifolds off, then heat up every stud on it to pull them out of the heads. The manifolds themselves were so bad, there was no reusing them, they had to be replaced. Out of all that though, they never leaked although it was getting there. Now with new studs and manifolds, it's good to go for years to come. The one noise I can't stand is leaky manifolds.

Sounds alot like what I had to deal with when I was living in NY. Thanks for watching !!

My mother has an 08 suburban with a 5.3. We had lifter failure, and a few other issues which lead to a total engine replacement (not my suggestion) and after 20k, I was driving it, changed the oil. All was well, 50 mile drive home after, and it sounded like lifters again. But after using a stethoscope on both heads, I couldn't determine a metallic noise comming from the valve train. Checked coils and they appeared to be fine as well. Now I'm wondering if this is our issue. Problem is it doesn't change once it gets to op temperature. Thanks for this, now I feel dumb and have something to trace down now lol.

I've recently started to keep a closer eye on my truck now that I'm getting rather high in the miles. I am worried that it could be a lifter being that I had a misfire about a week ago. I immediately changed my spark plugs that night. So far, so good. However I have been getting a lot of gas fume smells in my cabin, especially at a stop. I asked Uncle Google and it said it could be an exhaust issue. I looked under the hood after I got home from work and could hear a ticking noise. I thought maybe it was something to do with the spark plugs or coils. But after watching this video, it seems more apparent that it's a broken exhaust manifold bolt. But I'm going to bring my truck in for an inspection regardless.

Your awesome! Same sound same symptom on mine ! Thank you

Our 5.3 engines are known for that bolt. They have a work around adapter to fix that on the ones you can't get to.

A lady I worked with bought a brand new Mercury Mountaineer around 2000 or 2001 and I drove it once a few months after she got it and it did the exact same thing, but I think it was on the driver's side. I can't say for sure but I think it had the 5.0l V8. She had only just started hearing the noise a few days earlier and hadn't really given it much thought but I told her I suspected it was the exhaust manifold not being sealed to the engine. A few days later she had taken it to the dealer and sure enough, they found a couple of loose bolts and fixed it under warranty.

Just had mine fixed. I thought it was the lifters also but turned out to have a cracked flywheel!

@@victorcarreon7800 : Injector "ticking" is both a common & normal sound made by the electronically operated poppet valve inside each injector each time it's electronically "fired", on common-rail high pressure fuel injection systems. You can put a long screwdriver, a mechanic's stethoscope, or even a length of hose, to any injector body & to your ear while engine is running in order to amplify & hear the tick sound. Some side notes pertaining to exhaust manifold leaks: On a cool engine, soapy dish detergent water dispensed via a spray bottle to suspected gasket and/or crack areas also works well to find exhaust manifold leaks. Also, visually inspect for blown out exhaust port gaskets & exhaust soot trails from such areas. Most common exhaust manifold leaks come from burnt and/or blown out gaskets, caused by broken/rotted off manifold bolts.

I read the direct injection can have audible click. I only hear mine when I am outside the truck. Otherwise, whisper quiet. However, the clicking sound you are hearing is much louder and exhaust related for sure.

This is a common problem with Chevys over the last 20 years. Every single one I’ve owned, from new to used, eventually had this exhaust leak. I’ve had it in the 4.3 V6 as well as the 5.3

You would think as many years as this engine design has been around you would think GM could figure out you need bigger manifold bolts and possibly a redesigned manifold. I think every single one I've ever worked on had atleast two of the back bolts brake off, anywhere from 40k to 200k miles.

Nope, it’s a cast iron and aluminum cooling issue. Bigger bolts or a different manifold design using the same materials will do nothing. Compare the hemi cast iron exhaust manifolds to the srt cast steel exhaust manifolds. One breaks the bolts the other doesn’t nearly as much.

@@joshkrause2977 : Bingo Josh! You'll notice any engine that has a steel head and a steel manifold doesn't have this problem, arguably... ever. The true problem is that manufacturers have been using aluminum cylinder heads for about 40 years now, and then they bolt steel manifolds to them. To put it rather bluntly, it's just freaking stupid. Exhaust manifold fasteners can only take so much heat cycling and shear stress before they fail. That's the reality.

Loose spark plug also could also cause that squeaking noise. That was my immediate thought when I heard the squeak. When I do lifters I always replace manifold bolts. I hate when people don’t do that.
