oil catch tank

Hi,

AlexK- I run a small oil catch tank on the
E30 M3 /S54 but not on the CSL.

If you ever look inside your intake plenum there will
be oil deposits around the inside of it.

I believe BMW vent back from the Crankcase to the
plenum for Emissions, where the oil vapor gets
sucked back into the intake, but after the air filtre
for obvious reasons.

Its better to run a Catch tank, and something which
I will do on the CSL during the winter.

Regards,

The Gorilla.
