conan1977 Posted March 6, 2010 Share Posted March 6, 2010 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: Conan Link to comment Share on other sites More sharing options...
DJM/78 Posted March 6, 2010 Share Posted March 6, 2010 Either the Sea foam or the Lucas valve and cylinder lubricant . Put some in mine and smoothed it out a little . Link to comment Share on other sites More sharing options...
Eagle Posted March 6, 2010 Share Posted March 6, 2010 I vote for the old stand-by: Marvel Mystery Oil. Link to comment Share on other sites More sharing options...

88SporTruck Posted March 7, 2010 Share Posted March 7, 2010 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........ Link to comment Share on other sites More sharing options...
