I will have to give this one a try. A couple of years ago, I started to have a pretty decent leak at my rear pan seal. I pulled the engine and put it on the stand. I thought, while I am in there, I might as well put new bearings in the lower end. That's when I noticed that one of my rod bolts was yielded. So out came the pistons and rods to get ARPs pressed in and rods resized. That's when I noticed one of the head bolts was screwed up. Took care of that. Reassembled the engine, put it back in the car and fired it up. No leaks and was very happy. However, I got a strange noise when it warmed up. Figured out after pulling the engine that it was the corner of of one of the nuts from the ARP bolts hitting the pan after they heated and expanded. I rolled the engine over by hand and they don't hit, but once warm, ting..ting..ting..etc. So, I made a small relief in that area, put the pan back on, installed it back in the car and fired it up. No noise!!!! Yeah!!!! Oh, but the pan leaks. I did use a new set of side rail gaskets, but didn't use a new rear cork gasket since I used adhesive to the main cap. Guess I should have followed the process again. Anyway, the next time that [censored] thing comes out, I would love to use the 1 piece.
