Found a busted injector cup on a 6.0 Ford last month - it changed how I diagnose smoke
I was working on a 2005 F-350 out by the industrial park in Reno that was blowing white smoke on cold starts. The owner had already thrown two sets of glow plugs and a FICM at it. I was about to do the same thing until I got a good look at the number 3 injector cup with a borescope. There was a hairline crack letting coolant seep into the cylinder overnight. First time I found that instead of the usual injector or gasket stuff. It made me realize how much time I waste chasing parts cannon fixes. Now I always start with a coolant pressure test and a bore scope on any Powerstroke that smokes white. Anyone else find weird causes for white smoke that aren't head gaskets?

Buddy found a bad standpipe once that was dumping coolant right into the valley.

Yeah, it's funny how one hidden leak can mess up everything you weren't watching for.
