Seems like everyone here is assuming that if you have oil in your exhaust it has to be coming from or through the combustion chamber. Not so.
When you want to leave a nice smoke trail with your airplane so spectators can trace your fancy aerobatic manuevers, you simply inject oil right into the exhaust.
I think that is exactly what you are doing here. You have described your crankcase vent system showing how the crankcase gasses come out of the crankcase, go into your seperator, or whatever it is, and then the gasses GO DIRECTLY INTO THE EXHAUST. Guess what? You are in the air show.
I don't know where the oil is supposed to go that I think you are seperating out of your gasses, and the can might very well be full. Therefore I suggest, as someone else already did, check the canister. Then I suggest that you disconnect the line to the exhaust for the gasses and dump them into the air or into a bucket or something and then drive the car. Then figure out why the oil being seperated from the gasses is not going where it is supposed to go.
Don't pull the engine. I don't think you need to.

if the headgasket is blown you should get the classic chocolate milk oil......but you are not......is there oil in the water-coolant?
You can try running with the oil cap off...but be careful....it might spit ALOT......

I was thinking it was coolant because of some around a plug......... But I'm thinking that it was contamination. Oil looks great so far. No milk shake. And no uv dye in the exhaust. This morning i got the normal exhaust condensation and it was not sweet tasting. I'm really hoping its crank case

Jake, do spend some real time looking into that ventilation system before you pull the engine. I am currently venting to atmosphere (which I do not like) and seeing plenty of oil on my garage floor because of it. It is certainly enough to create a smoke screen, if it were getting cooked by the exhaust.

so i took it for a drive with the provent un hooked, and oil cap off. jesus thats alot of oil on my hood...... i let it warm up (smoked and puffed when idle, but cleared up) and took her for a little spin for a few blocks. now its night and i was trying to use the head lights of cars behind me to look for smoke, and i saw none.
letting her cool down (box fan on it to help) so i can check the plugs. if they are clean, i found my problem.
so that begs the question, how should i set this up for crank vent? that is ALOT of oil splashing/belching around (i have a moroso fill neck for the oil mounted on a block off plate over teh stock fill port and an AN fitting added for venting ) seems like a lot to me...

pistons still look a little "oil wet" but no pools. plugs look good. one more test drive tomorrow i think. this time with some thing to catch all the flying oil.

no stock smog. so the spot is open for a vac pump.
if you look in the picture you can see the mod block of plate. AN fitting and hose going to the provent and the oil filler cap.

I'm not familiar with your crankcase vent system, but I assume it has a check valve of some sort. See if it's stuck or in backwards. See if you can blow air through it (the whole system). Seems like high crankcase pressure is forcing oil past the rings.

Jake,
I've got an engine hoist if you want to borrow it. (looks like the indication is that you shouldn't have to pull it, but if you decide to and need the hoist let me know). *crossing my fingers for a crankcase vent issue that's easy to resolve*
