22r blowing oil from valve cover into air intake

My valve cover breather is blowing tons of smoke out and my intake assembly is coated in oil. the motor runs strong and has no other problems that I know of. Does anyone know what is causing this?

my guess would be valve cover gasket- not to pricey and easy to do- I did mine in less than 15 minutes. See my post in this section for more info.

No. you have a problem with excessive blowby. either your pcv system is clogged or there is just an excessive amount of wear in that motor; pull the pcv valve out of the valve cover while it is running and see what the deal is.

Yeah, it has a new gasket I will pull the pcv and check it out. I think it is probably worn though when I bought it the timing chain guide was in the oil pan.
