My '93 Grand Cherokee 4.0L with 290,000 miles is making a rattleing noise form the lower front of the engine. I have run the engine without the accessory (serpentine) belt and the noise is the same.

I am guessing the timing chain needs replacement. I am preparing to order parts - timing chain set, front main seal and gasket set. I see that there is a timing chain GUIDE also listed. My Haynes manual has no mention or pictures of any guide.

Where does the guide fit on the engine?

I am assuming the guide needs replacement.

Thanks in advance,

Eddie

 

t/chain possibly... but dont overlook your harmonic balancer...mine was smacking the timing cover only at idle or while wheelin...bet you a happy meal that is what it is going to be ... Cameron

 

Cameron,

Thanks for the reply ... I'm getting hungry for that Happy Meal! Too bad it's a long drive from Seattle to SoCal.

I replaced the harmonic balancer about six months ago. I had started rubbing on the timing cover ... making a grinding noise.

Unfortunately, it looks likes the balancer is going to have to come off again.

Thanks,

Eddie

 

you win...I get to keep the toy though .. ..the tchain isnt all that bad of a job...good luck

I ordered the parts today.

I also ordered the TIMING CHAIN GUIDE. I am not sure what the part is for or where it goes. I think it is a rubbing block that fits inside the cover. Better to spend $6 than to hold up the job waiting for one missing part.

Thanks for the help,

Eddie
