Only time I've ever changed the timing chain is when it broke and I never had any problems with engine malfunctions after replacement. That was on a 302 though.

I've had numerous cars with timing BELTS that I had to replace at 60k or 90k miles. Considering I often put over 200k miles on each one it was no big deal. But I've never had to replace a timing CHAIN on any of the chain-driven cars that I've owned.

Well this is false! The 4.0 cologne engine is SOHC not a pushrod engine.

Oops, my bad. Had it in my head that it was the other 4.0.

I stand corrected, and performed my own Homer Simpson head slap. And with the obligatory DOH!!!!
