Now I see I have oil running out of the right header on my new engine. Argh! It must have a torn valve seal on an exhaust valve to do that, the pan evac hose is dry. W5's have those deep cups around the valve spring even though they've been drilled to allow oil to drain out it's not going to drain it all.

I guess worst case scenario is a guide has come loose, it runs fine though and sounds really good. I guess I'll go pull the cover and take a look...
