Ok so here's the story, just finished reassembling the 4.0 in my 2001 4wd auto. Complete rebuild except for crank, rods and pushrods. Motor has run fine and i have put just a little over 400 miles on it for break in purposes. After dropping in the motor i used a fram oil filter and 10w30 dino oil with lucas zinc additive to help with the break in but here is my problem.
Friday night it has developed what seemed to be a knock which gradually got worse until i made it to my destination. A few hours later i got back in and it did not make the noise any longer. Saturday after it warmed up the noise came back and got very loud but we still made it home. Family members are telling me it's a rod but i have one friend telling me that it's probably the oil needs to be changed to get all the crud out from break in.
Any thoughts?? I'm almost considering a reman engine at this point as i don't want to get rid of my rig.
