2013 w204 c250 - Crankcase pressure with oil cap off m271 evo
Hi everyone. I’ve been trying to solve this crankcase pressure problem I’m having.
With the car running, when I pull the oil cap off there is (what I believe to be) excessive crank case pressure.
I replaced the pcv system hoses and check valve that is under the intake manifold and that goes into the block of the engine and hooks into the vacuum lines.
looking for any other suggestions of what else could be causing this crankcase pressure. Bad EGR? Turbo seals blown?
the car runs fine, idle isn’t rough, power is all there. CEL is on for MAP/throttle body sensor positioning. Other than that I’m lost.
any help is appreciated!

Hey Everyone,
DIsn't get a chance to tackle the valve cover last weekend due to a snow storm. Planning to do all the work Saturday.
-oil filter housing and gasket
-valve cover and valve cover gasket
-MAP sensor replacement and throttle bottle cleaning.
-oil and filter change
-coolant pipe from oil filter housing
Hoping the new VC fixes my crankcase pressure issue and stops the oil leak at the oil filter housing.

All,
I have successfully installed the new VC an can chalk it up as a success
my car no longer bobbles and blows the oil fill cap all over the place while resting over the fill hole at idle.
it has its suction (vacuum) back at idle and pulls the cap into the fill hole as it should.
Low rpm/slow driving seems much smoother now. Take off and accelerate are much smoother also. This is just from the ride home first impressions.
I would say if you are suffering from multiple oil leaks and are suffering from any or all of the symptoms I’ve listed above, you SHOULD REPLACE YOUR ENTIRE VALVE COVER.
here are a few pics of the valve cover off and the new one on. Will post videos shortly.
