I have driven 8100 miles since the timing chains, tensioners, guides, replacement and it's still nice and quiet. No leaks, turn and burn~

Hey I hope you doing well. I'm Mike ,let me tell you ,this was my first time opening and engine and change the timing chains and I really have a hard time searching for put the timing back, but when I saw your video an explanation made my life a lot easier because you said exactly what I need for finish that engine. Thanks .

Thank you for this vid. I’m in the process of replacing the head gaskets and all that timing mess left me with some apprehension. My mind is much more at ease now. Thanks again!

This is one of the best repair videos I have seen. I have this exact noise from my 2008, has been driving me crazy. Well done.

Wow, excellent vid. I feel this will happen to my 2014 in the future. Starting to hear some slop in that area. My main problem is keeping my foot out of the gas. These 5.7s will get it. Quite fun.

this video rocks....sir you have done an awesome job. I am right now doing this work, my 2007 toyo 5.7 blew the right head gasket. Truck has 272000 miles....but the gasket gave out. all original, chains, sprockets, lifters etc...all look brand new. however i have replace gaskets, lifters, cam chains both short and long. This engine is a monster and can be very intimidating, but I have surviced.... I just installed the heads/ cam cages, and working on timing chains. I wish i had the video equip to video,,,i have learned so much.

Great video. I reluctantly can't wait to use this as a guide. I'll be doing my cam towers as well during the process since they are leaking oil.

Use the Toyota 103 black sealer when you put the front timing cover back on. That stuff is strong and durable. It also dries quickly.so.make sure you have both parts cleaned and ready to go together before you start putting sealer on the cover and block. It get s tacky real fast.

130k and had a head gasket leak on cylinder 8, after opening everything up found one of the chains to be stretched so ordered a whole kit and put it in. THANK YOU SO MUCH for the advice on the small chains because I COULD NOT get them to line back up but got the big chains to line back up every time after manually filling it over, I kept thinking it wasn’t in time and I was doing something wrong but after I watched this video and you broke it down and said don’t worry about it I immediately felt dumb but SUPER HAPPY so thank you for the breakdown brother your the best!

You can probably get by with just replacing the tensioners. None of my chains were worn or stretched. The lower sprocket showed a small amount of wear but it was fine. Before you remove the actual tensioner, just make sure you tie wrap the chain tight so it doesn't jump on you. It should be pretty simple to swap the tensioners without removing the chains and guides as long as you keep the chain tight. Don't forget the chains always have some force on them from the valve springs and cam being halfway up or down on one of the many lobes. It all looks static when sitting there but as soon as a chain gets loose, it will quickly snap forward and your timing is screwed. Use the same method I used to get the crank bolt out. Don't use the "starter" method! That bolt was hammered on there! I used a breaker bar with a pipe extension AND a pipe wrench on the socket to break it free.

That 5.7 is a pretty good engine worth fixing for sure

Great detailed video.

Did you check cam towers leaks when that happens you will have to time it again

On the min 28:02 the intake cam on the driver side, the timing mark is in the 12o’c position then at 28:31 its shows that is the 10o’c position, which should be the right position. How do you get the cam the to the correct position? Thank you and btw great video!

Decent video. As a retired Toyota tech, no way I would suggest anyone take on this project and use aftermarket parts. Spend the money , get the factory parts where they count. There are several online sources that sell factory Toyota parts at wholesale to employee pricing.

I agree the labor is intense and it makes sense to use Toyota parts. Since I'm cheap, and probably will replace the truck soon, I wasn't to keen on spending $2.5k on OEM Toyota parts. Aisin makes many of the parts I removed from the engine. I think the water pump I installed from Aisin actually had a Toyota logo on it that was scratched out. The Mellings parts I installed looked virtually identical and the quality seemed good enough.... The timing set from Mellings was $325 I think.

Good Job

Carefully! I haven't taken my heads off so I can't help you there. I'm assuming all the timing stuff has to come out so you will need to do all the work I did PLUS removing and repairing the head. I would put back new timing stuff when you reassemble since the tensioners will probably fail in a few more miles.

when you turned it over by hand did you have movement in the new tensioner letting the guide move a little since there was no oil pressure there? freaks me out a little bit.

The tensioner has a ratchet in it so once you pull the pin out, it should shoot out enough to keep the chain tight enough until the oil pressure kicks it.

You could probably use an inspection camera on your phone to see the top two tensioners if you have both valve covers off. You could use PB, carb cleaner or starting fluid to melt the varnish off the plungers. I would get some small Tygon tubing (like the fuel line on a weed eater or chainsaw) and tape it to the inspection camera shaft and use it to navigate your way to the tensioners and give them a few blasts of cleaner. I do think it might be enough to melt that varnish off and free up the plunger. The job of replacing the tensioners is very expensive and not easy so I would definitely try to clean them before taking the engine apart. There are also 2 removable plugs on that timing cover that you might be able to remove and access the tensioners easier. Not sure if the accessories and serpentine belt cover those holes or not but it might be worth investigating it.

@danmccarthy206 I am a big proponent of using OEM parts. I see you used a reputable aftermarket supplier (Melling) for the chains and tensioners. Can you keep us up to date as to how long they hold up? That would definitely help us to know whether or not to spend extra on the factory Toyota stuff.

@danmccarthy206

Жыл бұрын

This engine is an "interference" engine which means the valves open far into the combustion chamber area, far enough that if they were open and the piston came up to TDC, the piston could hit one of the valves and bend (or break) it. So if you chain breaks, or slips a few teeth so the cams become far out of timing with the crankshaft, you could do some real damage to the engine. If that happened, you would have to remove the cylinder head(s) and have the valves replaced, etc. You might also damage the piston or cylinder itself if the collision is hard enough or a piece breaks of the valve. So, I would get this fixed sooner than later.

Probably about 8 hours of "real" working time. Most of the time I was trying to figure out how things come apart or what tools i need to get at things.

Even though I know dealerships essentially rob you with their labor and part costs, there are some jobs that I know I cannot do nor trust random "mechanics" that are buddies of the random guy who towed your truck. My belt tensioner was bad, so I was replacing it, but I stripped the allen bolt and then the bolt extractor I just bought broke off after catching the bolt. NOTHING I did could get it out, and I'm away from home, limited tools, and have very limited time. So I had to take my 2010 Tundra to the dealership. I about publicly cried when they showed me they would have to take the time chain cover off since the tensioner "couldn't be removed." Idk if they are taking advantage of a guy in a desperate situation (I have to take this truck home, 500+ miles away, then do a two-month long excursion for work, where no personal vehicles are allowed). Maybe the tensioner is "fuzed" to the cover, maybe it isn't. But this truck has 214k miles on it, and its well taken care of but with this job, at least I know I will have a new chain cover and new gaskets/o-rings throughout. I know the piston cover gasket has not been replaced, and those can go bad in time, so overall this can be a good thing. YOU'RE VIDEO HELP ME SEE THAT. All the complications of this job make me feel a little more at ease about all of this. Yes, I still think their prices are robbery, but in the end, I shouldn't have to deal with any of these gaskets for the rest of the life of this truck, which I hope will go for many more 100k miles. Great video, great explanations, great tips. Thanks for taking the time to make and upload this!

I have the same truck with 170k mile and I have always changed the oil every 5k. My guess is you are experiencing the same issue I had with the tensioners. You might want to try an oil flush product from Lucus or AMSOIL or similar. The root cause of my tensioners failing was a heavy varnish on the plunger. I believe if you can dissolve that buildup on the plunger, it will operate properly and the problem will go away. The question is, how many times do you have to run one of those products through your engine to get it to dissolve the varnish (if it actually will). I ran some Seafoam through my oil once for about 300 miles then changed the oil. It didn't do anything but if you run cleaner through it a few hundred miles before each oil change, who knows, it might work. Otherwise, you will have to take it apart and have the two main tensioners changed (at a minimum) to solve the problem.
