The fuel lines when you tighten them are pretty much good and tight. On the head bolts, on the V8s anyway, center out. 59 ft lbs, plus 90° plus 60° EXCEPT for the Alan head bolt that one is 59 plus 90° plus 40°. Rockers are 22 ft lbs and you don’t “have” to rotate the motor to torque them either. The lifter tray bolts are 8 ft lbs too

Back in 1977 there was an old green Chevy van at work. The guy that drove it had worked there a long time. The van used quite a bit of oil but ran well. When the engine started clicking at a stoplight, he would lift up the inside engine cover and put oil in the engine until it stopped clicking. The light would turn green and away we go. He said he had been doing this for several years. 😊

@AdeptApe Couple of things to note... The roller on the lifter most likely failed because the trunion bearings are on the way out. The trunion bearings on the rockers are notorious for failing. There are replacement trunion bearing kits to repair them all with upgraded needle bearings. I recommend replacing all the trunions on the rockers and not just the failed one. Also, the head bolts are one time use due to them being torque to yield - order a new set of head bolts from summit racing. I would also go with an OEM ac/delco head gasket for that engine. The new head bolts will also have the thread lock/sealant already applied. Also... since that block is based on the LS platform... look at the cam bearings... they should still be shiny... if they look dingy/rough... you'll be learning how to pull an engine lol. While it is apart... take the time to clean and replace the valve seals... they are easy to do... they are a hat design. Also while the valves are out for seal job... re lap all the valves to the seats before reassembly. The lifter trays are also one time use and should be replaced. If you re use lifter trays you risk a lifter rotating and wiping out the cam. Enjoy!

Came here to say almost exactly this. I would however say to do the upgraded brass trunion kit over new roller bearings, replace the exhaust manifold bolts with new high quality ones as they pop the heads off very quickly. I would also point out that you can eliminate that useless heat sink (or baffle) in the intake tube by putting a freeze plug or solid plug of some kind into the opening and tightening the clamp. Only other thing to maybe consider would be an oil catch can kit to avoid having to deal with the dirty valve issues in 20K miles.

Never mind this mess with whatever is causing the roller on the lifter to degrade wiping out the cam and seems to be an issue with some Ford engines such as the 7.3 in earlier production so certainly not exclusive to GM at all.

@@charlesb4267 Honestly the biggest issue is oil starvation. Newer engines burn more oil, from factory, and must be topped off regularly with GM dexos spec (non dexos burns even faster). The maintenance interval on the GM 6.6 in Isuzu trucks is 7500mi for “ordinary” conditions, and 3000mi for “severe” conditions. “Severe” conditions include dusty environment, frequent short trips, high idle times, towing, etc, basically everything you actually use a commercial/vocational truck for. Even so, it’s common for me to see units under “severe” duty getting 7000mi or even 10000mi oil change intervals. I’ve even seen 12 or 15k miles before changes. People wear these out, abuse and neglect.

You have found one of many reasons between GM and Ford I will always take the Ford with its problems.

Hey brother. I regularly work on the big brothers (LSx, LTx) to these GM V6 (I work on med/hvy, lots of GM). Sorry to give bad news. The piston rings on these have very light tension/pressure against cylinder walls, less friction = better fuel econ, at expense of burning oil from factory. These engines will burn their entire oil cap away between “normal” svc interval oil changes if not topped off. Best practice is use “severe” svc interval, but almost no one does. I routinely (two or three a month) see the V8 versions of these engines where fleet “driver” never checks oil, comes in for engine MIL, DTCs for oil press sens and camshaft actuator (variable valve timing, electric over hydraulic oil pressure sys) performance, and its 8qt sys has only 3qts in the pan… High odds this formerly fleet engine has only had its oil and filter changed at “normal”, or at normal +x%, intervals. High odds it’s been run until the oil had almost as much air as oil in the gallery, and they filled the oil, cleared the codes, and sold it off when it started making noise. For basically *everything* anyone ever uses them for, these engines are great if the oil is changed at the “severe” intervals, but junk after a few years of high interval (i.e. “normal” duty) oil changes. You said no abnormal metal in filter. Warranty procedure for everything as you’ve found it so far is replace camshaft, lifters (including fuel pump), cam bearings, oil pump (plus all one-time-use parts), and send it. Based on my experience, this is from oil starvation due to operator not checking and topping off oil, and extended service intervals; hate to say it, and I hate you’re going through this, but most of this engine probably isn’t far behind that lobe & lifter. My personal recommendation is get a reman’d long block and be done with it. Didn’t look like your van had an oil cooler, but if it does, replace that and its lines same time (oil cooler lines branch off from oil pan just above filter on V8, probably similar on V6), block warranty void unless cooler lines and cooler (if equipped) replaced same time, I think the flex plate to torque converter bolts can technically be reused with fresh threadlocking comp, but I always just replace them for peace of mind. If you want to roll the dice on the block you have, I wish you absolutely the best of luck, I know starting your own biz and keeping everything running is tough, difficult & expensive. For that, obviously you need new torque-to-yield head bolts, but the high pressure fuel pump bolts are also single use, so are fuel lines, and pump bolts require cam be clocked correctly so no pressure on roller, there’s a depth gauge tool for that, but if it’s at TDC #1 it’s fine. Cam actuator valve (holds VVT sprocket to cam) is also TTY, in an extd svc interval engine it’s probably junk anyway (internal mesh filter, not serviceable, restricts camshaft actuator pressure). Manual states to use new exh man bolts, those frequently break and cause exhaust leaks, so I always use new ones with the updated high-temp threadlocking comp for those. If you remove injectors, there’s a tool for that, looks like a bar with J-hooks that fit under the rails and pulls injectors and rail as an assy; the tool is to prevent damage to the head. If the injector bores get damaged from injector gouging its bore during removal, the head is scrap. Injector gaskets and clips are single use, there are specialty tools for the clips and gaskets at tip, but there are tricks if you don’t have those tools, send me a msg I’ll explain. Either way, best of luck with this, bud. I’m sorry you got a turd, and I hope it doesn’t hold you back; hope it doesn’t put you underwater when you’ve just barely launched. Keep pounding!

This is all great info and I have often wondered what causes all these lifter related issues that seem to plague modern pushrod engines. Improper lubrication is at the forefront of my hypothesis. Low viscosity oils used today, higher operating temps (207 degF thermostats), extended idling (vocational trucks idling ALL day everyday), no/low oil due to drivers who don't care to check oil regularly, extended service intervals, etc. I am sure there are random quality issues where parts are not to spec as well. Right oil in the right placed at the right time in the right quantity.

You mentioned correct oil; that’s why not only do you need correct viscosity, it also has to meet GM dexos specs, otherwise it burns off even faster than what I mentioned above. When oil starvation is found, warranty usually won’t pay for it. The customers (fleets) are demanding “efficiency” (lower fuel costs), and they’re getting it.

They do make a small tool to help remove and install stretch belts. They are becoming more common across auto manufacturers. GM has been using them since about the 2014 model year for vehicles with a mechanical vacuum pump for the brakes, since those engines have direct injection, they don't produce enough vacuum for the brakes.

One saving grace, it didn't look like a " active fuel management" setup (that cancels cyl to save fuel) that has it's own set of problems and additional costs to adequately FIX (not factory repair) the problem.

I tend to mark the fanbelt with a direction arrow. Reversing usually starts a squeal.

General rule of thumb, things loosen in the direction they turn. Fans, lawnmower blade bolts, etc.... So they tighten during normal operation.

GM seems to avoid radiator drains, probably a cost cutting measure.

OK Josh, I'm sorry to see what a mess your engine is in. To me it's sinister to build engines like that. It's like the throw away mentality of the 1970's.

They'd go 1/2 million miles between rebuilds. You'll get I'm sure, please be patient with it so you don't blow a head gasket. ben/ michigan

You don't need much to stop lifters from rotating. That is provided you are supplying the right amount of CLEAN oil to them. The cam and roller are typically domed (particularly for the roller on a diesel to help ensure consistent pressure across the entire width of the roller) so that they run in the middle and so they should dynamically self align. The 3406 engines people said had problems with the retaining clips but it really was the oil quality that allowed the lifter to touch the cam and that would then apply an uneven force rotating the lifter and ripping the clip around. I would seem that the forces in a gas engine are FAR lower and so (spring rates etc) so even with it touching etc it still didn't spin.

Re: balance shaft comment, the inline 6 diesels you're used to are naturally balanced but a v6 (especially a 90 degree one like this) is not. Adding a balance shaft not only makes the driving experience nicer but stops the engine from shaking everything attached to it loose like the manifolds. Very few v6's omit them.. my Ranger's 3L does and im constantly popping vacuum lines back on etc 😅

I just started watching, but i remember when you pulled the valve covers. You had little to no oil to the rocker area then, and it won’t be better now. You have a lack of oil pressure to the rockers. you need to look at the oil delivery system. Yes, you might need lifters, but that is a symptom, not a cause.

Busman’s holiday, Josh. Smaller, lighter parts but a cramped work space. I wonder what would cause one (so far) lifter to pit like that. I trust the rest of the repair will go quickly so you can get back on the road.

The extra air capacity on the intake on those NA engines is supposed to help maximize the rpm range, it’s a manipulation of the air flow to improve a variety of things for different vehicles. It’s like the cross valves and such on the supper cars, just a simplified version. I’ve seen testing on it and it seems to be legit if done properly, just putting random boxes on your hot rod won’t be beneficial unless you get crazy lucky lol

Put in a performance cam and a supercharger, and you'll be golden (until your transmission explodes into little tiny pieces). :3

This is why i always hated working on van chassis

ps, i know you already ordered parts but it might be worth looking for a low milage one out of a non-commercial vehicle (maybe a wreck). sorry to be the bearer of bad news...but Ive seen similar situations that turn into a constant plague of chasing issues. At the very least take a good look at everything you can- bottom end, cylinders, etc. If you see anything that looks iffy...run like hell

Better than Chevy lumina van, no dog house, or if you worked on toyota sienna engine lays on its side underneath passenger seat. Once the doghouse off, your working on a table pretty much in a full size van. You should try putting in a engine in a van on 4 post lift, lots of fun!😂 Ill take a full size anyday.

I love the long sleeve t shirts too, I wish they made super cheap disposable ones 🤣 I wear clothes out fast, started wearing the blue one piece garbage man coveralls when I wrench these days.

You're likely to find a wiped out roller and cam lobe. Pretty common issue with late model gm engines

Hey your doing great! The shock of going from heavy equipment which was primarily designed with the necessity of maintenance to automotive/light duty where the engine/drivetrain is packaged to give maximum room for driver Do you think an oil analysis might have revealed metal. A tip for you about going into passenger?lt is to remove everything in your way its actually faster than trying to work around things

Very common issue on gm engines, the needle bearings in the lifters like to come out and usually take the cam out, also common on hemis. Head bolts are tty and aren't reusable, also look into the issues with dexcool eating intake manifold gaskets.

Need major engine overhaul, that’s all it needs
