Thanks,

Going to change the dip stick o rings and hope its not the main seal behind the timing cover!

 

Even if that is leaking, it's not from crankcase pressure.

 

I get that now. Is it common for Leaks to only happen under load?

 

99.9% of the time it's the dipstick leaking when that happens.

 

Now that my car is gone- this is sort of a moot point, but if I had it all to do again: One of the things I would have done was install a crankcase "PSI" gauge so I could monitor what is going on down there. The kicker is I had a spot I wanted to use when I did my shift console gauge pod and I poorly decided to only use one spot when I should have done a second. I think a 0-10 PSI gauge would have been perfect. If there is any more than 1PSI the seals are NOT designed to hold that back.

 

I think part of my issue is that i have a vented dip stick tube with a filter on it and seems to spray oil out that filter. Working on getting a stock tube now.

 

i use that to return oil, not to vent pressure
