EA211 Oil Catch can
Posted: Tue Feb 20, 2024 6:04 pm
Hey fox,
After many years of troubleshooting why my engine is running rough on cold day and why I have some missfire, I took, fews days back, the decision to remove the intake manifold to check
my intake valves.
And with no surpise, they are full of carbon build up thanks to direct injection.
With the older port injection, valves were cleaned with fuel and with time, stay clean.
Pictures of my engine (Cylinder 1 and 2):
For info, this car is my daily. Running only on premium fuel and premium oil (0W30 Shell), changes every 10000 km.
Only highway, almost no city.
I have to fix an appointment with a specialist to clean this crap.
But, now I'm looking to avoid/reduce this ammount of crap for the futur.
An Oil Catch Can seems prettry obvious. But because EA211 engines are not made for sport/racing car, there is no official kit like the 2.0 TSI.
This engine have a PCV installed on the bottom.
But depending on the pressure ratio, oil vapour will be sent or in the intake manifold, or in the low pressure side of the turbo.
-At idle (low speed)/engine off: non return valve on the intake manifold open. On the turbo low pressure side, it close.
-At high speed (boot demand): non return valve on the intake manifold close. On the turbo side, it open.
So I'm hesitating for the installation: turbo or intake manifold side.
I'm considering mainly turbo side because on this engine your are driving mainly on torque and so, turbo pressure.
My idea is simple and it's like this kit (from brasil):
Bought an other foam hose (between engine over head to turbo) cut the hose in the middle and keep the two VW connector and install rubber hose between each connector to the oil catch can.
