Historic touring cars have a little spring that holds the dipstick in. They also run a much larger catch can, externally vented. Group C 308s ran similar. The AR1 and also NS2R are abgood idea, lots of 15" sizes available But can create another problem, lots if liad going through 50 year old wheel studs, stub axles. Coupd eventually look at long heavy duty studs, and "stub stiffeners " to help the bearings..

[@davohq1724]

Thanks for your input. I'm still learning about the car while doing track days. I never thought about the studs or stub axles. What are stub stiffeners? Now I'm worried that my wheels are going to break off.

that oil seepage from your oil filler on the tappet cover could be caused by the cover not having a baffle in it i found on some of the after market tappet covers this caused it to leak as you said i put the original tappet cover back on problem solved

[@davohq1724]

There's a baffle in there. It only leaks when I'm constantly revving it to 5500rpm. The next rack day will test my theory.

Crankcase pressure, shorten your hoses and vent both sides to atmosphere. I’ve had the same problem, it’s gotta get out .

[@chrislandsmann8872]

I had the same problem and just hooked up a Pcv valve to the intake to create some vacuum. No more leaks and idles smoother to

[@davohq1724]

I was going to vent both. I just didn't want to get a defect for not having the PCV hooked up.

I run a rubber hose clamped on where the dipstick goes and sealed on the end. no chance of any oil leaks. Just pull it off to check oil level. never had an issues the last 10 years of track days. Do you have baffle plates under your rocker cover breathers. Stops a lot of oil going in the catch can.

[@davohq1724]

That's a great idea. I'm going to do that with the dipstick. I have baffle plates under the rocker cover breathers.
