The only time i have seen that happen is with a stopped up catalitic(sp) converter.
I had a buddy that had a motor that leaked oil out of every seal and the converter was stopped up changed it and the leaks went away. Its something to checkout.

I agree with rikard - you have serious blowby issues. Try a wet and dry compression test - I imagine your dry compression will be much lower, indicating worn piston rings. Check the PCV valve and breather filter.

I second doing a compression check. If there's enough pressure in the system to blow out the PCV valve, you definitely have something clogged. I'd also just replace the PCV valve without thinking twice, they're like $3.
Secondly, not to be rude at all, but you seriously need to use punctuation in your posts. I had to read your post about ten times or more simply to understand what it was you were trying to say. I imagine there were quite a few people who could have very possibly helped you out but didn't, simply because they couldn't understand you. That's a lot of information and symptoms to chug through without.

Ok, here's my predicament. I have an 89 f-150 300ci. I was driving it the other day, it was just fine. Got were I was going. When I was leaving, it didn't want to run highway speeds. I limped it home and it was pouring out smoke. When I stopped, my oil pressure dive bombed then came back up. Now, what happened is it spit my pcv valve out, that's where the smoke was coming from. Also, my #1 spark plug was broken. Fixed that and now it will run highway speed. But to fix the pcv valve, I put a piece of tape around it so it is in there tight. But now i have oil leaks coming from everywhere: the valve cover, rear seal (i think), pushrod cover, and oil pan. It had no oil leak before this. What would cause this to happen? Can anyone help? Thanks in advance.
