Well I talked about this in another thread, CleveSaab host the video I sent you in this thread if possible. Then engine will rev between 1300-1900 rpms freely. Now this does not always happen, like today on my way to atuozone to have the codes read it did no such thing. But yesterday it did. And there has been another time where it happened then stopped and then started up again.

I got the codes read and recieved 3;

P0132
bank 1 sensor recording high voltage

P0300
multiple misfire

P0133
slow response of bank 1

now the guy said that this is typical of a bad o2 sensor? What else could it be?

This might not be related but I have noticed oil being pushed out of my BOV. Its all over the area around the valve. This seems rather serious and maybe its somehow related. I noticed both problems about the same time. My question is how is the oil getting into the intake pipes and so much so as to be coming out of the BOV. Now this coating of oil might be triggering the bad sensors in bank 1 and also causing the misfire. But since the oil seems to be a constant problem...always happening, why isnt the revving problem happening all the time?

I hate when things are wrong with the car. Any help whatsoever would be very welcome.

Hey, i dont have an answer, but i just wanted to say that i have a similar problem sometimes. I always thought it might have something to do with the IAC or the throttle body, but i cleaned both and no real improvement. Well, i cant really relate anymore because my car has been off the road for over a week now, so i sorta dont remember exactly how it is ;oops: .

Mark, I am not a mechanic, but could it be that the oil in the BOV is coming from a dead turbo unit? You should see smoking elsewhere if that was the case. The misfiring issue could be a DI cassette. Is there anyone else who could lend you swap your DI and see if the problem persists?

My first thought was a failing turbo. I have someone who could lend me their DIC if need be. The more I think about it, the more I think its the oil in the cumbustion chambers and intake manafold and what not that is causeing these bad readings and causeing the misfires. Mabye not, but I would really like to know why the oil is in the intake plumbing (i know a tiny bit is normal) but enough to have it coming out my BOV.

Well I talked to a turbo specialist and he said that the oil inside the intake tubing might be caused by extra pressure in the crankcase. Now would this be caused by the c900 valve cover I have on there now? Maybe its not flowing right or something? Its either that or the turbo is going and the seals are beaking. I personally would rather the c900 vavle cover be whats doing the damage. Anyone hear of this being the case? Its all I could think of.

I seriously doubt it is the lid in the pot. Come on, it fits, it bolts perfectly, I just do not see how it would be the valve cover!! But, hey, what do I know. All I am saying is my money is in the turbo :(

Bingo, Rico. Probably too much crankcase pressure. Check/replace your PCV valve (they tend to go bad) or fix the breather if you put one on where the valve should go.
Bad idea to mess with even seemingly simple things like valve covers unless you know what you're doing.
Good luck!

Any chance you installed the pcv check valve backward? If so, you are pressurizing the crankcase when on boost...Make sure the pcv check valve is pointed towards the TB to allow air to move out of the crankcase back into the TB when at idle, not the reverse.

Check the hardpipe routed back to the intake for excess oil being dumped back into the intake if the check valve is backwards.

The pvc check valve is installed correctly and should not be bad. I bought one from the dealer less than a year ago. Its the uprated one that is found on the current 9-3's. The design was changed a little from the 900 to the 9-3 or somewhere after '96. As for the valve cover I only have one tube on the underside which I think is causing the problem. I think that it has one tube due to being from a c900 8v and not 16v which would have 2. Atleast thats my theory. I will be converting back to the ng900 cover in the next few days, very little daylight free time between school and work.

That should solve it, so I hope. Or I will have to have the beat tdo4 I have sitting around rebuilt instead of my t25. Which would be nice but I'm more in the market for suspension right now.

Update. The revving of the engine has stopped, but the oil out of the BOV has still persisted and the check engine light is still on. What on earth could this be? turbo failure? Oil that is just left in the pipes from when things where wrong?
