blowback

[SGRIM]

This is part of a previous long post so reposted this seperate. My problem is a little blowback coming out of valve cover breathers causing a little drip. The breathers are VERY SMALL not right size. When take breathers off a small amount of white smoke blows out. But no leaks no water in oil and no leaks anywhere else, doesnt appear anything coming out of tail pipe. I was wondering if normal with this type of RACE motor or maybe return holes stopped up car sat a long time I think. I just praying nothing internal. THe car has the GN1 aluminum heads and valve covers I do not think valve covers on correctly and used a cork gasket, should it be rubber? But very worried about this blowback.

do you have a stock intake manifold or a aftermarket.
it is possible the pcv is blocked off . my manifold that came with my champion heads from bgc is blocked off . this will cause some smoke through the vc breathers at idle.

Does have PVC

The heads do have the PVC valve!

my pcv valve is still in place its just blocked off in the manifold.
