Started it up, all of a sudden, blue smoke everywhere. Coming right out of my exhaust tip. Idles like a subaru w/ cams. Clear misfire. Oil spewwing out of my oil cap like there was to much crank case pressure and thats where it started leaking at. When I removed the oil cap, you could feel the pressure come like an over heating car when you remove a radiaitor cap.

I think either the headgasket is done or possibly valve seals. The motor has about 500 miles on it including new valve seals, rings, headgasket, etc.

Idled for about 10 seconds, started backing it up, seen smoke, shut it down, crank case pressure HIGH!

The oil leak is 100% internal and causing a a misfire and running down through the turbo, out through the tip.

It's not valve seals.

SO I pulled each plug. Every single one is good. Dry, good burn. hmmmm

I think the only real answer to this is to pull the valve cover and do a leak down test. If it starts coming out from the valve seals, there is my answer. If it comes out from anywhere else, more than likely, a head gasket.

Leaking valve seals will not cause the car to run on less than 4 cylinders, nor will they show up in a leakdown test.

So what do you think it is? Anythings I can check before I do a leakdown test which wont happen until tommorow?

I pulled the plugs, pulled the fuel pump fuse, cranked it over. Nothing came out of cylinders. Dry inside. That would lead me to think its a bad turbo but because the valve cover vents are putting out alot of pressure, it makes me think what went wrong.

Under a leakdown test, air will take the path of least resistance. Air won't creep out the valve seal before it goes out the intake or exhaust. If you hear air coming from the exhaust or intake, it means you have a burned valve. If air comes out the crankcase, it's either leaking past the rings, or you have a hole in the piston. If it leaks between cylinders or into a coolant passage you have a bad headgasket.

I would suspect turbo if the exhaust ports or spark plugs are dry, but that doesn't explain the reason it's running on less than 4 cylinders.

Try a compression test real quick to try and narrow it down, since you already have the spark plugs out.

Rings are brand new, OEM. Gapped correctly.

We will just wait until tomorrow and see what turns up

I have a question. What would happen if you looped the PCV valve to vent tube on the side of the valve cover? What damage would that do?

Too much pressure in the crankcase. As far as what could fail, too much pressure at the oil drain on the turbo causing oil to get pumped into the exhaust wheel or comp wheel.

I have a stock return line and a SS feed line from the head. I dont understand. How would that cuase it to run like a subaru (misfire).

I can go out and check whatever. What should I check.

Without any tools to do a compression test (which is where you probably want to start with diagnosis), you're a bit limited as to what you can do at the moment.

I didn't say that it would cause a misfire. But it can cause a major oil issue because the oil can't drain down into the pan. If you slow that oil down coming out of the turbo, it will force it's way past the oil rings in the turbo.

Quoting Kenny_Kline:

Um, did you do this? Or were you just speculating.

That would cause all kinds of crank pressure issues.

How did you determine the oil rings are bad? You said the plugs are clean no?

The plugs are clean.

SO if the valve cover was blocked off for 15-20 seconds, what issues would happen?

Something let go, a seal somewhere most likely....

It's not oil control rings though.

If you looped the valve cover breathers, effectively blocking them off, you probably pushed oil past the turbo seals into the turbine housing. This would also be why your plugs are dry.

Over the winter, when it got into the single digits, my catch can and lines on 503 froze up and I ended up with a smoke screen. Considering how much I use that car for skiing, I promptly put it back the way the factory had it. Works great.

Why it ran on less than all cylinders I don't know.

Lets say the turbo is shot. How would that cause the high crank case pressure issues?

The turbo doesn't have to be shot for excessive crankcase pressure to push oil past its seals and into the turbine or compressor housing. If you block off the crankcase vents, then the pressure created by the pistons moving up and down is what does it, not the turbo.

You still haven't answered whether or not you ran the car with the vent lines looped?

I just pulled of my intake. I found a crap load of oil in my intake. The turbo has no shaft play up and down or in and out. PERFECT!!!
