I was cruising down a street (duh) and I sort of went WOT in 3rd gear when I felt a lose of power. I looked at the rearview mirror and there it was, a cloud of blue smoke.

I pulled over and let the car sit for some five minutes and the smoke disipated, no more smoke. I hit the road again and boosted it and nothing came out. I just changed the oil about a two days ago with that aparatus, the one you insert a plastic tube into the dipstick and I might have added a little too much oil.

So I open up the hood and I see some oil around splattered around the intake pipes. It was dark but I could see a glare in the plastic parts.

I had a problem also with one of the turbos not kicking in. So I boosted .5 bar and below at WOT, but sometimes when I performed the road boost test the car boosted just fine up to .8 bar and proceeded to do the standard boost pattern. I took it to the local rotary shop and they told me that it was one pill called the "orfice" (spelling check) and that is why I wasn't boosting.

Question, why isn't there any smoke comming out anymore? I drove and boosted it to Kinko's to post this up before I move it and no oil came out on my way, but there is a bunch of oil splattered. COuld this be because I added too much oil to the system? Thanks for any replies.

 

You blew an intake pipe. Probably the rubber coupler. Find the leak and fix it first.

How can blowing an intake pipe cause all the oil splattered inside and the smoke that comes out of the exhaust? PLease explain. Thanks

 

OK, I tried to understand what you are trying to say, but I quite can't make it out.

I know I'm not running rich. I know how "running rich" smoke looks like and I know how "burning oil" smoke looks like.

You say "oil moves from the turbos to the intake pipes". For what reason and how? There is some oil around my intake pipes, sure.

To me, it looks like an oil line burst or something. I don't know where or how or even if there is such a line. I've had another turbo car where the turbo was leaking oil through the compressor side because the seals were screwed, but there was no mess or oil throughout the engine compartment. It is late and I have no way of looking into the matter right now. With the light of day I shall though.

I would think that if one of the turbos has a broken seal I would still be burning oil at all RPM ranges. As I let the car cool for three hours and I started it and a puff of smoke came out, a little more than usual and then it disipated. I warmed the car up and made my way home with no more smoke comming out. I even went as far as to take it to 6k RPM's to see if more smoke came out, nothing. The boost pattern was the same and is as follows: When I am at a stop and I floor it I would hit .6-.3-.6 bar shifting through 1st, 2nd and 3rd gear. I would then roll to 50 mph and I would go WOT and I would get the normal .8 .5 .8 pattern with no smoke! WTF!! Thanks for any help.

 

The oil spatter would be caused by the rupture of the hose. The intake pipes usually have a light lining of oil inside of them due to turbo seal blow-by. It would result in a complete loss of boost as you describe.

So I suggest finding the burst and replacing the part. It's not hard.

The blue smoke is harder to immediately diagnose, and usually means burning oil. But whether that's just a one time thing, or your turbos are screwed, you should get them boosting again to find out.

Well, I pulled out about 1qt of oil and left it at full. Could it be that the added oil increased preassures and forced oil out of the seals and into the compressor and through the intake pipes?

I have located the puncture on the intake pipes, it is a tiny one, but still a crack. Also, I cleaned the rubber hose that connects to the IC and the IC, they were soaked with oil. Eithey way, I am boosting the car today again so I can check if oil is still leaking. I would be looking for more oil residue inside the IC pipes, right? Thanks

 

Overfilling the oil isnt a smart move

 

I know. I used one of those aparatus that uses vacum to pull it out, inserting a probe through the dipstick.

I started the engine again and made a 3/4 thottle pull and I only hit .5 bar, but I know why. Some smoke did come out but it dissapeared after 2 minutes of hard driving. I did some more runs and nothing. I am on my way to further test and to check the IC for oil, again.

 

You will find oil in the IC piping, this is normal for a broken-in set of turbos. However, lets say you remove the lower elbow at the IC and oil runs out - not what I would call normal. Mine are always wet with oil, but never enough to run or drip.

Did you replace the part with the crack/slit in it? I assure you, it needs replaced and it won't boost right until that leak is resolved. You can't duct tape it or anything silly. Once you get it replaced, clean the oil off the outside of the parts and look to see if it leaks again after a couple of runs.

Dave

 

why didnt you initially tell us you had just changed and overfilled the oil? thats your prob. and you still probably have a boost leak!

 

I did say I overfilled the thing. I have removed the excess oil and I am now not burning oil or smoking anything. The boost problem remains, but I haven't fixed the pipes yet.
