I'll have to get a recording of it, but when its cold and randomly at other times it makes a good squelch and then loud ticking. Some times its like a knocking which is scary
Some times it does it only for a few seconds, others it will do it till I rev it or drive it or restart it, and some times not at all
Think it's just the lifter/cam or a piston skirt (or both!)?? I just changed the oil and it seemed fine, got a bit dark quickly, but not to bad. I should have stuck a magnet in the oil pan and checked if I could fish anything out, cant remember what piston is made of though?
I put Restore engine restorer in it this oil change and it has quieted it down a lot (makes it go away much fast so far), but it still does it after sitting overnight or a while at times. I've tried different filters and oil but it doesn't make a difference. Gas mileage sucks too, though my driving style doesn't help that any! Jeep only has ~73k miles on it.
I have the stuff to do the rear main and oil pan which is leaking a bit, but since snugging the rear pan bolts its not too bad now, so I am saving that for warmer weather (and the clutch which has oil on it!) I don't know if I should save and wait and tear the upper engine down too and replace the cam/lifters while I'm at it? Or do the pan/rms/clutch when warmer and hope not to find pieces in the pan of the pistons!
Sorry for the novel, just worried about this. The Jeep has been a money pit since I got it, issue after issue I shouldn't be having.
Any easier ways to check better without tearing it apart? Probably not eh?
Thanks for any help or advice in advance
