sounds like excessive blow by, do a dry compression test and then wet compression test and post the results.
if you dont know what those are, its very easy to learn what they are by looking it up on google. i help those who help themselves. -------------------- |

your pcv valve is most likely the cause. it's usually located in between the top of your valve and the intake manifold. take it out and shake it. if you hear it moving back and forth it's good. if you hear nothing it's clogged. it's only about 5 bucks to replace so it's an easy fix.

well you could go out and buy a filter that sits on top of your valve cover to try and compensate for the amount of pressure in the head. i'd go buy a new pcv valve and see if that fixes the problem first though.

It might just be that the dipstick rubber is worn and you could use a new one.
