Sooo... I just got a broken bolt out of the cylinder head and I put my engine back together in about 8 hours with breaks of course, but when I finally finished and started up the jeep the knocking was still there. I checked the oil numerous times to see if the oil was low but the reading said it was fine. I drove it around a little bit to see if it got worse... it did.... I was going about 35 and the jeep shut off completely... I threw it in N and put my caution lights on while I cruised trying to find somewhere to pull off to. Boy, without power steering... it's a challenge to turn. I got out checked the oil because the check oil light was flashing but the oil was fine. Im beginning to think my rocker arms are f***** (pardon my french) but they are seriously making some noise... Ill post a video in a new thread so feel free to throw some thoughts and comments.
