a PCV 'leaking oil' is a symptom - not the root cause.
You need a compression ring job. The crankcase is getting excess blow-by from the rings and is pushing oil out the PCV...
(Me? I would just install an oil catch can and be dilligent with sea-foam-ing the engine once in a while until it gets worse...)
Well I'm agreeing with this,... chances are your compression is down. This is the FSM data for our engine,.. I'll bet you're near the 119 psi mark.
I'm kinda thinking you might be in a "good money after bad" situation (as my dad would say). A ring job would be a lot of money,... and your car IS running OK except for the oil burning and blowing through your engine. If I were you,.. I would just leave well enough alone and be diligent with the Seafoam (as P-Funk mentioned) to clean the crap out of everywhere it is getting. (in with the oil, gas and up the brake booster vacuum line). Chances are that oil is getting past the oil rings and burning up in the engine and in the cats.
I will bet you that the PO's neglected their scheduled maintenance especially oil changes. Then that grit and grime filled liquid sandpaper circulated through the engine wearing everything out.
I'm a firm believer in changing oil every 3,000 miles (5,000 km for us Canucks). I'm pretty sure my PO's did regular oil changes and I change mine myself with the cheapest oil I can find (except no-name). A lot of what makes expensive oil better is the extended "service intervals" but for the same money, you can change cheap oil twice.
I'll bet your PO's let their oil go WAY too long.
My car has 214,000 km (133,000 miles) and doesn't burn a drop of oil. I'm feeling pretty lucky about my purchase,... I got it when it was 8 years old just as the novelty of a new car is wearing off for people and they start to neglect it.
I'm all curious now,... I think I'm gonna do a compression test on my car,... I know I've got a tester somewhere,... I'll bet I'm still pushin 160 psi ???
What is the mileage on your car ????
