Ok I think I figured out the source of Oil in my Intake Manifold.

Both hoses that run from the Valve Covers are regulated by pressure regulator valves. Those hoses both have oil in them. Those hoses run directly into the Intake Manifold right? Since I have my car apart I can't just look lol.

But but following the trail of oil it went from the Valve Cover, pressure regulator valve, down the hoses and into the manifold where it weeped through the cracked Intake Manifold Gasket on to the Block or was quickly burned off.

Keif remember when I was getting those valvetronic error codes with No description? I wonder if that was the problem....Just Bad Pressure Regulator Valves

Anyway I'm sure this is the problem. No bad pistons No bad pistons!

During my waterpump install the small black Hose that attaches on the boot right infront of the mass air flow meter to the Throttle broke of at the base. It started running rough after that. I can't figure out where that hose goes to. Somewhere in the back of the engine and probably unrelated........But maybe. parts 4 and 7
