This is a LQ4 (6.0) with unknown miles. I also didn't get to hear this one run before I pulled it, only got to hear it pop and stumble on starting fluid. So I figured this would be a candidate for a rebuild. And if I was going to rebuild it might as well throw some HP at it.
I have the engine completely apart and everything looks fine. All bearings look good. Typical carbon and gunk.
I discovered that the best cleaner for carbon is easy off oven cleaner. Then clean that with water with a little degreaser in it and then brake cleaner and air gun off. Finally coat everything with WD40 to not let it flash rust.
As usual, I got side tracked with the cleaning of the engine parts and decided to build a hot tank for the block. I had a 55 gal food grade barrel and a burner for oil fryer. I added some copper tube with holes in it for air agitation.
