suprise main seal? No leak whatsoever before. In fact the last "leak" I had was the old turbo seals were leaking into the hotside causing it to smoke on heavy acceleration. Fixed that with a new turbo. What are the chances I might have damaged a gasket when I was testing last time before the new waste gate went on and over boosted? It was dry under the car for the 3 weeks it sat in the garage.

Both oil lines are dry at the connection points. The feed line was a little oily in the middle where it runs close to the block, also the engine grounding cable that comes off the valve cover to the fire wall was pretty saturated with oil as well. Maybe a valve cover gasket?

When I was crawling around under the car I noticed the oil seemed to be heaviest above the starter, near the back of the block where the transmission mounts to the engine. That's why I thought rear main seal. I'm hoping it's something simple like the valve cover gasket, as I need a reason to take that off and repaint it anyhow!
