[Fot] CRANKCASE EVACUATION SYSTEM

I might have to give it a try. Of course that means Peyote is going to rust.

GM has a typical check valve for $10-15 if you make your own.

This system will:  "...provide better piston ring seal, less intake charge
contamination, and reduced oil leaks caused by high crankcase pressure."

This is from a circle track catalog. A little marketing hype built in here, I
sense.

Moroso, Mr. Gasket, and Renegade provide these kits to the circle track guys.
There are pieces uneeded for Triumphs and no hi temp poly tubing, which may
be the most expensive item.

I have no understanding of why they are not permitted in the SCCA GCRs.
Likely for good reason in certain applications...V-8s?

But for TR3/TR4 engines, it seems like an appropriate modification.

I was putting a lot of oil into the frame rails and then would dump it ON the
exhaust pipe at Turn Five at Road America. Not a very pretty cloud of oil
smoke and of some concern to the corner workers.

After going home, I would let the TR4 drip for a couple of weeks, then wipe
it down.

This system changed all of that.
