Engine Tick? 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.
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.
