Vaccum from oil filler?

[taylorsomero86]

Heres the story... car ran fine before supercharger install. Put in powerdyne bd11a, 42 lb injectors, 255lph pump, 70mm accufab tb, msd 6btm. smog delete(plugged holes in heads) Put it all together fired it up and it was blowing from the oil filler. Took off the upper and lower intakes, replaced gaskets and now it does the opposite.. its sucking from the filler. The pcv is working fine. Trying to get it to run correctly and bring it to the dyno to burn a chip. Is it possible I got the lower gaskets out of alignment a bit? Im confused!

Do you still have the line going from the valve cover to the TB? If so...TAKE IT OFF!

that was my first thought too

nope it is capped off and it builds vaccum with or without the supercharger running. Ive only driven it around town a little bit takin it real easy with the boost retard turned up.

I'm confused on what the problem is?

can you elaborate?

Ive never seen a motor make so much vaccum from the valve covers. It didnt do this before I took off the intakes. The lower gasket was shot so we replaced it. With a normal oil cap and no breather itl run for a while n start squealing(crank seals?) and you open it up and it just inhales mean. How normal is that much vaccum coming from the crankcase? I didnt think it was normal.

I have had the lower intake to head gasket slip during installation before.

The result was a massive vac leak through the lifter valley.

There really shouldn't be a significant vac from the crankcase.

Hope you find it the problem
