reverse pcv vacuum???

So I have been getting oil in my air cleaner. It's getting in thru the oil fill tube that connects to the air cleaner. I disconnected the pcv, and oil fill and removed the air cleaner. Saw fumes escaping from the oil fill vent tube.

Just wondering why it reverse flow.

If the pcv valve is working properly, then you just have more blowby than the pcv can handle.
Make sure you are getting good suction thru your pcv valve.

BTW, at full throttle, that breather intake line you are referring to, is supposed to reverse flow.

Pcv checks good.
At full throttle? I just thought it was always reverse flow.
I'm checking my compression tomorrow. Not sure if this will let me know anything further. Like about blow by.

Your motor just has worn out piston rings is all. If compression checks out good and even on all cylinders, but a little low, I'd keep driving it.

Thanks 1983.

I'm on the hunt for an other engine to rebuild.
Not to much luck, but that's okay as i'm not ready to pull the trigger just yet.
