I'd be a little concerned and at the very least do a compression test or better yet, a leakdown to see if there are any unhealthy cylinders...

The stock pcv valve is suspect at best when doing your evac kit inline w/ a oil water seperator. Chuck the stock pcv and go to O'reilly's and pick up a Chrylser pcv part # 2103. You won't have that problem again I can assure you that much but if you want to still use an inline oil water seperator, by all means do so. Only draw back to their pcv is it has a 90* bend on one end but nothing a little extra hose can't cure.

Found it on AZ website. So what is different about this PCV valve vs the stock one other than being plastic and 90*? Is it less restrictive than the stock one, thus allowing more crankcase vacuum?

I have been having oil leaking out of the front and rear seal and have pulled the dipstick and checked for pressure and don't feel anything. The car usually leaves a spot a little smaller than a half dollar everytime i shut the engine off. The motor only has 3000 miles on it. Could it be crankcase pressure causing my problem and if so how would i fix it the right way and the cheap way?
