My '91 has a new engine, but they used the old head without a rebuild. I had some lifter noise, which is normal with the 4.0. Recently it became a little noisier, and I drained a pint of oil, replacing it with a pint of Marvel Mystery Oil. Within 30 miles it was much quieter. From what I understand, MMO has solvents that clean out the gunk that cleans out the passageways in the lifters allowing them to maintain pressure. I would bet that almost any lifter solvent/cleaner would do the same thing. I use MMO because it's worked for me before.

Is this coming from the engine? If it is it sounds like you might have some lifter problems. Or the worse part is if you have a rod knocking. Intrepids did have some egine problems.


Can a exhaust leak sound like a lifter pecking on a 5.3 chevy motor?

Yes it can, but try to isolate the sound by using some thicker weight oil and/or oil additive like lucas to quiet the ticking lifter. If the noise doesn't change it's probably an exhaust leak, if it quiets down you might have a collapsed lifter.
