Oil Dry Sump Goodness


How many times have you run at PIR?

When I had a valve cover breather setup like yours I would fill a catch can in one 20 minute session at PIR. However at Pacific Raceways it would only be full at the end of the day. PIR side loads the car for much longer giving the oil time to build up in the head.

A drain back catch can system is the way to go for the head breathers.

As for the smoke at startup? Compression and leakdown to confirm the engine health. Pull the downpipe and check for turbo shaft play
