How would you rate mobil oil in general. I am not talking about mobile 1 of course, but regular dino mobil oil compared to others. And he does change his oil every 3000 miles or so. He just adds oil as necessary so the engine doesn't get low in between oil changes. Oh, teleplayer, I noticed that you cleaned your evaporator. I tried doing by following the instructions in the tech section of this site, but it didn't work for me. I couldn't even really get to the evaporator. Did you follow the same instructions, or did you do something else. Thanks.

mobil one.. mmmm.. I'd try some "high mileage" oil.. i somehow think its a gimmic, but try it out. I believe there is a "full synthetic" one.. see if that is feasable. If you can get it, go for it. Do 2-3 oil changes on it first though, that way you'll get the full effect.

hey guys, this could be lower intake gaskets... those make you leak oil into the upper intake like crazy. when i replaced my upper and lower gaskets, I had pools of oil sitting on my lower intake manifold. The two 'hidden' bolts were even more hidden, because they were sitting below an inch of oil...

Yes, I did it by removing the blower motor "resistor". It'* not really a resistor, but an electronic circuit. When you remove that, you have a rectangular opening maybe 2 x 3" to work through. It'* not easy. I started with a vacuum cleaner and a piece of wire, picking loose all the big stuff like pine needles, etc. A small inspection mirror helps you see inside.
I then used some soapy water and various small brushes, to brush away the crap from the face of the evaporator. It took a long time. I avoided the use of solvents like brakekleen, I didn't want to smell that crap inside the car.
I also used a garden hose a lot. And I did make the mistake of soaking the carpet !!!
Hope this helps.

Thanks a lot for your replies everyone. I just replaced his pcv valve, and the old one was covered in oil inside and out. Don't know if that means anything, but they should not have oil on them, right? The old one seemed fine however, when I shook it, it rattled like the new one.

sputnik767, please do this test: With the engine idling, remove the oil filler cap.
Did you notice air rushing in? -like there was a vacuum in the crankcase?

I actually tried that today, and I did not notice any vacuum. I tried listening for it, but could not hear anything over the engine. I did put my hand over the hole, and there was no vacuum. Is that good or bad. Thanks to everyone for all your help by the way.

So, I'm right back to my first suspicion: And that is worn, or failing oil control rings.
My experience years ago (different engine) was EXACTLY

As I have stated before, a compression test may come out just fine,(-even the "wet/dry" test) if the top two rings (compression rings) are still good. But you can still have failing oil control rings (the third ring set, double scrapers w/expander).
If you are really lucky

Other folks may be able to share some positive experiences with using products to "clean/ or free sticky rings."
