Another CJ blowing oil

well it seems my 85 CJ decided that it wanted to start blowing oil up into the air filter out the dip stick and any other hole it could find. The situation is this...at idle the pressure is fine but as soon as I start to drive the pressure stays at 50 and doesnt drop till I idle for about 5 min. Shes got a new PCV valve, and I just changed the oil, hoping there was just something in the oil. I know this problem has been posted many many times, I was just wondering if someone knows the cause, and a CHEAP fix? Any help at all would be helpful. And if it comes down to it and I need a new engine...anyone know of a place to get one???
Thanks all,
TheJelloJeeper

Re: Another CJ blowing oil

yea, mine too.....but i made an easy and cheap fix until the engin completely dies. i posted it today, check it out. but oil has not shoot through the dip-stik! did you over fil it by chance? hi/low auto parts here in texas had the cheapest rebuild. they said it would be 975 for a long block and a metel valve cover-and that is pretty cheap! when mine goes out, i will spend a weekend putting that sucker in! good luck.

Re: Another CJ blowing oil

I didnt get oil out the dipstick but it did blow out from every where else. My problem turned out to be the fuel pump; it had a hole in the diaphram(a mans greatest fear come true). This thinned the oil and filled the case until it had to go some where.
