the top guide on my saturn 93 sl2 failed made a loud ticking noise -- baiscally it has a hard polymer between the metal of the guide and the chain the plastic shattered i had fun finding the pieces -- any way the plastic was gone and the chain was rubbing straight on the metal was able to fix that just by removing the valve cover and removing two bolts -- the majority of the plastic ended up in the valve chamber itself I'm sure i didn't get all of it out but oh well

thats half of the reason i'm rebuilding, i'm going to tear the entire block apart, and scrub it clean

So you can tell when you need a new timing chain because theres a clicking noise? SH*T haha...90k miles....guess its time for a new one. Anyone have instructions on replacing this? thanks

you can take the front cover off and inspect it, but with that much work you could just replace it. if the oil gets dirty/dark fast(in my case 700 miles) it is also a good sign of bad news.

very simplifyed how to:
support engine with hoist
remove engine mounts, belt, crank pulley
loosen exhaust downpipe
remove oil pan, valve cover, front cover
replace all timing components

that is a very basic how-to from memory, if you plan on doing it, i suggest getting a repair manual like Haynes or chiltons or such(i have and use both)
