Sitting at idle i was just relaxing just thinking and I started hearing what sounds like a rod knock. it sounds like a rod but when I get my stethoscope it quiets down obviously but when i put it up to the valve covers i don't hear anything out of the ordinary. I crawled underneath and didn't hear anything unusual either i could just hear the crank moving around but nothing like a knock. The oil pressure as some of you know in a previous topic has been all over the place but lately its been behaving for the most part. In the morning when its cold its at like 50psi idle and 70psi on the road but when it warms up its like 30-40 on the road and 15-30psi idle. I'm thinking of replacing the oil pump this weekend to be on the safe side since that isn't to hard just annoying. Is there anything else I should look for when I pull the pan or something i should look at first before i pull the pan off? And what oil pump should I get? The ones on the shucks web site look like the ones found in SBC motors but those attach to the bottom of the distributor which the 6.2 obviously doesnt have. Recommendations will be much appreciated.
