[911pcars]

Chris,
I was talking to Gene Scott who races his red '67 911 in VARA (father/son act featured in Excellence) about this a couple of months ago. The younger Scott, Mark, was having venting problems similar to yours (large quantities of oil in the catch tank). This was described in some threads related to this a few months ago. Their solution (I think it was successful) was to add additional baffling of some sort inside the oil tank to help separate blowby and oil mist.

Maybe Mark will see this thread and respond with some insights.

As an aside, Honda made an attempt to reduce piston ring friction in their turbo F1 engines a few years ago by deleted the ... piston rings. They thought a few pounds boost lost through add'l blowby was worth the reduction in high speed friction. They had too much blowby and went back to their previous design.
