M54 Engine Smoke/Oil Leak
 
Had a huge oil leak and engine was smoking out of the sides of the hood,vents and into cabin. I went ahead and got the valve cover gasket replaced. Problem is the smoke is still present and so is the oil leak although not as bad. The previous leak blew a crap ton of oil into the passengers side of the engine bay and a huge puddle on the floor. After i got the gasket replaced it runs smoothly again.CCV was deleted right before the valve cover gasket and was checked to make sure it wasn't causing any issue. I drive not 5 miles from my house and the smoke started pouring opened the hood to see where it's coming from and couldn't pin point an exact spot. I opened the oil filler cap and noticed it was smoking as well(along with yellow sludge possible left over from bad ccv that i'll address)

the oil is pooling in one spot in the ground at what looks to be the back of the engine compartment near where the firewall would be if anyone has any input on what i should be looking for i'd appreciate it greatly.

Clean the engine with Oil Eater (when cold) and you'll be able to pinpoint the leak a lot easier. At this point it'll only be a guess but I don't want to say it and jinx anything...

just tried that now i'm seeing the smoke coming from a specific spot and where the oil is dripping a couple drops it seems to be smoking from where the rear oxygen sensor and manifold is

Who replaced the VCG?
What brand?

It looks like it leaks from the VCG again.

Also, the CCV delete, any photos of your current setup? Maybe the pressure is high in the crankcase.

VCG is barely 24 hours old but i don't see anything else that could possibly be leaking
A simple catch can was installed with a PCV inline ill post pics when i'm with the car again
i'm getting misfires on cylinders and camshaft sensor errors as well even after they were replaced the first time i got the codes
