Hello everyone, I have a question that maybe one of you could answer, what does a bad lifter sound like? Five out of seven mornings, and after the car has sat at work all day, I get a medium pitched, hollow loud knock coming from the engine, if I rev it up a couple of times, the sound gets real quiet, but never really goes away. It has been doing this for quite some time, say 50K miles. I am getting ready to do a top end rebuild on the thing, and was thinking I would replace the lifters thinking that maybe one of them is what is making that sound in the mornings. I have removed the pan, because I was told the sound might be a rod bearing going out, rods looked fine, no metal in pan, the engine sounds fine apart from that knock that sounds like a valve out of adjustment. Also I had the oil pressure checked and it was fine, at start up and hot.
