Baystate Jeepers

How hard is this to do? Seems to be pretty straight forward according to the Hayne's guys, but i know it can be an expensive job to have a mechanic do for a $66 part. Is the extra $$$ just because of the disassembling/assembling of the front clip, radiator and water pump (which will also be replaced at the same time)?

My skills are so-so, i can't rebuild an engine, but i'm pretty good at following directions and putting things back where i found them.

It's time consuming more than anything else.
You'll need a harmonic balancer puller and installer (loan a tool at most part stores).
Any particular reason you're replacing it?

I was talking to a guy whose buick (or pontiac, can't remember now) was making the exact same noise. He was told by his mechanic that it was the timing chain. Seems like a good bet to me.

I had a nissan sentra that had to be junked because i couldn't afford to replace the timing chain, don't want that to happen again.

Well the timing chain on a Jeep 4.0 is way easier than on a Nissan GA16DE (managed to do it without pulling the head like the books say you have to)

A mechanic likes that kind of job 'cause it's lots of shop time to do!!!!!

You gonna be at the Go Topless Day? I can take a listen to it and see if it's really that.

Hey Paul, sounds like it's worth taking a ride up just for that!!

What kind of noise is it making? Jeep timing chains are typically bulletproof and usually last the life of the engine (200K+ miles). I would investigate other possibilities. If I could hear the noise, I'd probably be able to help you.

Also, depending on the age of your buddy's Pontiac, it may have nylon timing gears. Yep, nylon!

Yeah, I remember those nylon timing sprockets. They kept me in business when I was running that parts store. Thank you, GM
