Went I went racing Sunday, I had turned up my boost from 25 to 26psi after my first run. Just after my 2nd run I came back to the pits and smoke was rolling out from under the hood and I was like WTF! Here the dipstick blew out and oil was everywhere. A good thing I had lots of rags with me. The dipstick is the original one and it appears to be fine. I have nothing to compare it too. I pulls out pretty easy. I'm not sure how tight they should be in there. Maybe it is too loose?? I understand that crimping the dipstick tube is a definate no-no which could lead to more serious problems.

So I don't understand why i build up all this crankcase pressure. I have a JAZ Products catch can. Both fittings on the valve cover goto this catch can. The PCV valve was replaced with just a straight thru fitting.

I did a compression test about a month ago and the cylinders averaged around 150-158# with a warm engine.

Am I ready for a rebuild on this '99 that has 90k miles? Are my rings shot?

Thanks for any suggestions.
