What would cause this?

[Goon]

Hey all

I got a question about a car, but its not a holden It happens to be my sisters car and its a really crappy problem

It's an honda accord 86 4cyl si auto, when it drives over 80km for a short peroid of time it spits oil out into the air filter area even out of the airfilter box, what would cause this?

I'm thinking about getting another motor sent up for brissy 2nd hand but its like over 800k's away..

Thanks to anybody that might be able to help

oil coming thru the pcv hose, into the intake, maybe clogged oil galleries, too think oil, i dunno, just taking a few guesses.

blocked breather or as hakhawk mentioned pcv valve faulty if not that over full of oil worst seario blow bye
