What is going on???

[porschedude911]

So after a slight overfill on my 2.0, I followed the boards advice to drain some oil and drive hard. After doing so I put in new plugs. It smokes exactly the same. Under full throttle, no smoke, after every shift, or lifting on off, and randomly, there is a burst or trail of smoke. I had about 3/4 inch of oil on the dipstick prior to 20 minute drive. Once home, nothing was on the dipstick. After drives prior to and including spark plug changes, I am getting white scum.(Water) inside the air filter housing and all over the fill cap and fill tube. Smoke in pic's is at idle of 1000rpm. I'm still trying to get into a reputable shop. But would sure like to know what is going on. Thanks all!!

I don’t know about the water but the smoke sounds like worn valve guides.

If it were me, I’d start over with the proper amount of new oil.

i agree with above. almost like your oil was contaminated with water.

Pistons and cylinder heads are nos for 2.2. and were included in recent rebuild. So shouldn't valve guides be new? I am definitely burning oil, I mean its going down. Oil is definitely correct, right level, and no chance of water contamination. My drives were on bitter cold days, which a friend said could lead to the residue on oil filler cap.

I agree with myflat6, I would drain some of your oil and put it in a glass container and let it sit for a day or two and see if any water settles to the bottom.

That's good advice. Rather than assume it's bad oil, let the oil speak for itself.

Well. That is a lot of smoke...as you stated.
Are you absolutely sure the two large braided hoses are hooked up proper?
I haven't put mine on backwards... So I don't know what it would do. But maybe it makes smoke.

Another thing i would do is remove both large hoses. See which hole the smoke comes out...You don't need the hoses to drive the car.

The hose from the oil filler neck is connected to the air filter housing on my car. When I remove the filler cap, less smoke comes from the air filter housing, as it comes out the filler neck instead. Is that the correct hose set up?? Thanks guys, this is driving me nuts.

Yes, the filler neck hose connects to the airbox. The other hose connects to the case breather.

I'm still leaning toward lingering from the overfill since in your other thread I understood you to imply that you drove the car about 1000 miles before the overfill, and that it was without smoke. I agree with other replies here that at this point I'd drain the oil completely (tank and engine sump), and start over with fresh oil. If the '69 oil tank is similar in capacity to my former '84 Carrera (which is larger than the tank in my current '72T), I'd start with about 8 quarts and go from there.
