Welcome Visitor! Please take a few seconds and 
I've got my junkyard engine torn down to a short block and began work on the rear main seal, cleaning up the pickup tube/pump, and just managed to clean enough varnish out to pull the first lifter. Immediately could tell it was cupped. Im running some erands to among other things, grab a can of spray that will better aniahlate varnish, but am curious what yall would do. I don't want to remove the crank if I dont have to, but I think it might be wise at this point to pull the cam out for a looksee.
