hey, I'm in the processes of fixing up a Jeep Grand Cherokee I picked up from my brother. I understand this isnt LS1 specific but Jeep forums stink and I always get good info here...
I got it cheap so figured if I have to throw and engine into it, I'll still be ahead but this is what I found when I got it:



I continued to pull the timing cover off to find some broken pieces of timing chain guides and some other items that would come new in a new Timing Chain Assembly Kit (OHC, 3 timing chains total)

The problem is a new timing chain assembly kit is $400 and the noise still sounds like its coming from the rear of the engine... also the gaskets kits to pull the head and timing cover and everything total $300! (To replace the engine would be ~1800)

Do you think just replacing the timing chains will solve the problem? Or what will?

Thanks!

if the timing chain broke most likely some valves kissed the pistons and it bent/broke some pushrods aswell. In short, I highly doubt the timing chain fixes the ticking sound.

the timing chains didnt break, only the guides and some other timing related components, the chains still look okay, just a little loose

IF the guide broke, then there was a chance of the timing being altered, which could cause issues with the pistons hitting valves, bending pushrods, I would definately inspect the valvetrain. You also have the high possibility of trash in the oil pan.

Is the noise coming from the top of the engine? I was working on a car once, that I swore had a bad lifter, TICK, Tick, tick, Ended up being an injector. Alot of things can cause the noise, sometimes isolating and locating the sound is harder than fixing it.

it happens almost all the time, but some times goes away... noise is def coming from the top of the engine
