Well the past couple of years I have had a head gasket slowly leaking on my truck. It was getting to the point that the bottom end was getting kind of noisy and it was not firing on all cylinders until it ran for about 10 minutes. I had started fitting a v8 in it until I came across a 3.0 with 80k miles on it for cheap. They said it had ran good, but I think they might be liars. I cleaned up the new engine, replaced front and rear main seals, timing cover gasket, valve cover gasket and oil pan gasket to try to prevent any coolant/oil leaks that I had issues with previously. I installed it and fired it up and there was a dead miss. Compression check on #6 gave 0 and the rest were ~145 - 150. The bottom end sounded good. I hooked up an air hose to the spark plug hole and it was going straight out the tail pipe. I pulled the heads and this is what I found.
That is on the exhaust valve. The piston and the cylinder walls feel fine still, so I think I am fine with just replacing the head. What would cause an issue like this as I want to prevent it from happening in the future?
