So I got a pretty bad driver side oil leak. When I park the car it pisses all over the floor by the morning. Quite a bit too and I can’t figure out where the oil is coming from exactly.

so to my knowledge a few things carry oil driver side. Let’s go through them one by one.

first is the oil filter and it’s pedestal. Neither of these are leaking. That side of the motor is dry.

next is the oil pressure sending unit. It’s not leaking and dry as well.

the next thing is the oil fill neck where it connects to the metal neck, that too is dry.

now I’ve noticed the top spark plug wire plug on the front housing (closest to the front bumper) had some oil on it dripping down.


so I’m thinking could the oil that goes from the bottom nipple on the oil fill neck to the hard line on top of the motor that goes to the turbos be leaking?

can I simply route this line to a catch can instead or block it off? Af least to test if it’s leaking that is because from my understanding this bottom nipple is just used to redirect extra overfilled oil to the turbos to be burned off.

I can’t think of anything else that could be causing this oil leak. Also, my car isn’t overfilled on oil so why would so much oil be coming out of the second nipple if that’s the case? Bad PCV valve maybe? The PCV is pretty new though (less than 5000 miles on it)

nothing else is on the driver side that carries oil right?
