oil catch tank

[mattsay]

Guys,

I need to check the baffle plate and / or gauze in the cam cover, as some of you will have seen my horror thread about oil in my air filter.

If I need to fit a catch tank - can anybody tell me how to go about it and offer any pictures of their own installations?

Cheers.

Have a look at the"Air box finished" thread, looks like a catch tank on the N/S inner wing, neat job too

Update.

The baffle plate seems fine and the gauze is just about visible under the plate.

The car ran much better today on a brief run without the breather or air filter attached. There is a definite case that oil was contaminating the mixture when the engine had warmed up. I wonder if themixture had to be very rich to compensate and also the timing advanced to compensate for that!

However, the amount of oil coming out of the breather pipe is still worryingly high, even without the vacuum from the Weber, so I doubt the conversion is to blame. A catch tank will work I'm sure but there surely shouldn't be that much oil in the first place.

I know that you guys have suggested blow-by but the compressions are pretty good (140 to 150 psi "cold" and "dry") and within 10% of each other. The engine is a recon 16k miles ago.

Can excessive crankcase pressurejust be one of those things?

What next??????
