Timing Chain Cover

I would like to start by saying thank you to TeamRush. Your advise on my engine miss while in park was right on and the TFI upgrade to boot. My engine runs smooth as silk. If you are ever in Joplin, MO I will gladly buy the beer.

My current problem is a cracked timing chain cover. It is not yet leaking any oil. Will I hurt anything if I continue to drive it until I can get a new one put on? How could I have cracked it? It is cracked in the middle about 60% down from the top. None of the bolt holes are cracked. Has anyone else had any problem with these? Are they a weak link? If so, where can I get a stronger one. The only place I have been able to find one is 4WD hardware and one at the local bone yard.

My Jeep is a 1983 CJ-7 with a 258 straight 6. TF 999 auto tranny. If I need more detail let me know.

Thanks,

Re: Timing Chain Cover

You are welcome on the ignition....

I don't have a clue about the timing cover. I don't do I-6 anything very often.

How about the crew! One of you guys have the answer to this, I'm sure....

Later, Aaron.

Re: Timing Chain Cover

Double check that "crack", it probably is the casting flash or marks that are very common on these covers. If it is, new ones are still available from Jeep, if you can't find one. Hope this helps, good luck!

Re: Timing Chain Cover

CJ--Mag is correct.
If it's not leaking, it just very well may be a casting flash line.

If it's aluminum (I assume it is, CJ Mag is usually correct), and it really is cracked, I'd have it welded before I replaced it. (Unless there is something major wrong with it inside...)

Just a thought...

Re: Timing Chain Cover

I am familiar with the casting of these timing covers. I should have added that I rebuilt the engine around 10,000 miles ago and inspected everything at that time. Unfortunately for me it is cracked. I am interested in welding it if it can be done on the Jeep. Is that possible? I do not yet have a welder and would have to take it somewhere to have it welded. I can pull the Jeep apart and put a new on though. I can see and feel the crack. I have found one at a bone yard for $35.00. 4WD hardware has them for $39.99. Jeep wants $79.00 plus $18.00 for a spacer. No where else do I see that I need a spacer. Can anyone tell me what applications needed a spacer? The parts guy at Jeep of course could not. I have been wheeling very hard lately and feel it will be leaking very soon if I do not get it fixed before I go out again this week end.

Thanks,

Re: Timing Chain Cover

The "spacer" is actually a dampner to control timing chain slap, it's used on the later model 4.2s and is a "good thing". If the cover isn't cracked badly, just use some epoxy to seal it up, there's not much stress on the cover.
