Engine starting to get a lifter Knock

[conan1977]

Good morning to all. I have a question about what kind of additive or oil I should add to help with this slight knocking. It started about 2 weeks ago in my ladies 1999 Jeep Cherokee sport (inline 6). It has 137k on it and has always been well maintained (regular oil changes, filters, injectors cleaned yada yada yada). I was thinking about adding Seafoam (as I love this stuff). Anyway, do I need something with a more of a detergent affect or something else. We do not have the money (both of us are going to Grad School...broke as joke :smart: ) to rip this engine apart. HELP Please.

 

 

:cheers:

Either the Sea foam or the Lucas valve and cylinder lubricant . Put some in mine and smoothed it out a little .

I vote for the old stand-by: Marvel Mystery Oil.

Once had trouble with 'bowel movement'. Took a couple shot's of Marvel Mystery Oil. Haven't been constipated since.

Hey you keep believin 'em, I'll keep tellin 'em.

MMO helped my XJ's 4.0 lifter tap quite a bit. Didn't make it stop completely but with 230k on it I expect it to make some noise........
