My friends a retard now my car is smoking like crazy sr gt2871

[slideslidegnarslide]

Long story short I don't have a place to store the car so it's at my friends house. I got a new catch can and he figured he would be nice and install it. Well he ended up putting both breathers from the valve cover on the can. So he let it warm up went in grabbed the steering wheel and when he came out it was smoking like crazy.

Basically he mad it a closed system so it just built up pressure. Catch can is filled with oil and he removed the catch can to see if the smoke would clear. Well it hasn't.

So what did he hurt? The turbo or the motor? I won't be able to look at it till I get home from work and just wanted some ideas. Any input would be greatly appreciated.

Pardon the extremely crude image but I'm not sure what you mean...is this how he hooked it up?

This is MG, right? If so, give me a shout on my portable communication device later.

Also, what you're saying is that you have a sealed catch can, as in the blow through type? IIRC, to hook one of those up, you need a source of vacuum or overall lower pressure on one side, and then a tap from the stock vent system (high pressure) on the other side. This means that when pressure builds up, the oil would get caught in the catch - right?

If he were to hook in up in such a way that the system was building pressure but not venting it, a bunch of different things could happen. First thing I would check is for any leaking gaskets and seals. Usually when you have excess build up of pressure in the crank, these are the first to go. Basically the easiest methodology here would be to follow the lines from the can back through the motor until you find what went wrong. Figure all a PCV system/catch can does at the most basic level is vent excess pressure. If the pressure wasn't being vented through the PCV system or the catch can, then it had to go somewhere - meaning that a seal/gasket somewhere more than likely failed.

When no venting is available, oil goes through turbo seal instead of going down the oil pan.

Revert to stock, maybe change your PCV, and just drive, it should clear with time.

Now you have solved your problem, ask someone in the street to punch your friend in the face for modding and driving your car without your consent, and yourself for having idiots friends AND letting them have the keys of your car.

Idiot friend is a close buddy who is helping me out. I know he has money so I know what ever is broken will get fixed.

The deal was he was supposed to call me any time before he drove it and I don't know why he worked out with out me knowing.

I admit I shouldn't have gave him the keys

But yes it was hooked up like the first picture so I'm guessing the turbo seals are what's going to be bad if anything. So I'm gonna clean out the piping then drive it around and hopefully the smoke goes away. If not he owes me a turbo

It would blow out the dip stick and valve cover gasket before the turbo seals, not to mention if the car was just at idle pressure would be relieved though the PCV valve. Sounds like something else is going on.

Turbo seal dont blow, it is a matter of pressure differential. The seals get somewhat sucked and oil goes through. Once pressure is back to normal, the seals work correctly again (but there is still oil in the exhaust, and it may take some time before it is gone completely.

Check oil level too. If you really are afraid do a compression test, i cant see it killing the rings or a piston that fast (unless the car was not mapped and he put some boost in it)

I'll be taking it apart tonight and I'll get a better description of what happened. No it's tuned and hopefully it's fine thanks for the responses so far

[slideslidegnarslide]

So we pulled it all apart and there was oil in the intake, front mount piping and a ton in the front mount itself. He really was just trying to help so now I feel bad about the title of this thread.

Any way we took everything apart and cleaned everything out with gasoline. Waiting for it to dry then put it all back together. I also still have to dump the catch can and hopefully install it right because we ran out of light.

You guys think everything will be ok? Or are my seals beat in the turbo? The turbo literally has 300 miles on it.

Time will tell I'm gonna slap it back together and see if it stops smoking.

[joe3180]

was that oil in the piping and ic before? because it could just be from earlier and not from this incident if you had just put a catch can in. In which case if it is that excessive you may have had a problem before hand.

[Croustibat]

The seals should be ok, they are not gaskets, basically they do their job with pressure differential. When the air pressure differential is not what it is supposed to be, they get sucked "in" the turbo and oil pass through. When the pressure is back to normal, it is supposed to seal again, as the air pressure differential pushes it firmly against the flange. It might take a bit of time, but it usually clears. Just clean what you can and monitor your oil level, it may keep smoking for a bit but it should stop after all the oil that went in the exhaust is totally evacuated.

If it does not stop smoking after a couple of hundred miles, it means something is still leaking though.

[slideslidegnarslide]

Oil definitely not there before the incident. Actually found a small boost leak where the oil was dripping from on the passenger side of the front mount. So I know there wasn't oil in there before. Thanks for the help guys when I put it back together I'll update the thread so probably Thursday. I got stuff to do today.

[slideslidegnarslide]

Everything got put back together.i started it let and let it warm up. Began revving it and it began smoking. Then I took it out for a blast to see if it would clear up. 1st pull, crazyyyyyy smoke. Second pull, (more like just building some boost then letting off) a lot less smoke. So I figured do a solid 3rd gear pull and see what happens. So after the pull and I look and the mirror and it was relatively clear. Maybe a slight haze if anything. I parked it and and it was still smoking some revved it a couple times. Still smoking quite a bit.

I'm going to compression test it this weekend but I think it will clear out.

What do you guys think?

[Mikester]

I think that there is probably a lot of oil pooled up in the intake manifold that still needs to be worked thru. Also, take the PCV valve off and shake it- It should rattle freely... It could be stuck open. If it doesn't rattle easily; soak it in a cup of gasoline for 10-15 min and keep doing so until it rattles easily.

In stock form, the SR charge piping sort of functions like a catch can. There is suction on the inlet to provide the vacuum under boost... That oil vapor needs to go 'somewhere'...
