Smoking Turbo?

[KiamyDSM]

Its not my car so i dont know all of the problem. I guess turbo smokes. What could it be?

The seals being bad?

What color is the smoke? If its white smoke it can probably be your turbo or head gasket, but most likely its your turbo mine was and another buddy's too... use the search forum and you will most likely encounter your problem and how to go about fixing it.

 

[KiamyDSM]

pretty sure hes got a brand new gasket and the engine only has 20k on it. so he might need a new turbo?

 

[arodgst]

Yup most likey its your turbo, my buddy's turbo smoked from the hotside and the shop told him it was a bad seal... you will most likely need a rebuild that is if the turbines are still good.

 

[KiamyDSM]

if its done should i get a small 16g or a big?

Okay, is it your car or not? If it's not, then find out what goals the owner has, and let him/her make the choice. Is it the turbo smoking, or the engine? Find that out before you go throwing parts at the car.

Pull off the intake pipe and check the turbo for shaft play. A little side to side play is normal, but in and out is no good. It is most likely the turbo seals, check the intercooler piping for oil.

As far as your question about the small 16g vs big 16g, check out this thread.

My turbo/manifold smoked visibly but not a ton of smoke. It was just coming off that area I figured it was the anti seize stuff I used on the bolts. This was first start up with a new turbo though. Hasn't at any other times.

When i got my car it smoked so much it was like someone was holding a fogger under my hood...... later i found a blown head gasket and melted piston on top of all that the turbo was shot as well but it sounds like your turbo is going out check the intake and intercooler piping for an exessive amont of oil

 

[KiamyDSM]

if there is alot of oil in the piping what would have to happen next?

 

[JFatch1890]

Most likely its bad turbo seals.As stated check the ic piping for oil.You can or he can w.e either buy a new turbo and upgrade or rebuild that one if he or whoever can't afford a new turbo.There simple to rebuild as long at your compressor wheel didn't hit and cause any damage cause then it threw it off balance and you will need to send it to a shop then you might as well just upgrade.

i would take the turbo off and either re build or replace it, then throughly clean your intake and ic piping and also your intercooler.

 

[KiamyDSM]

alright thanks

 

[91dsmgsx]

its my pleasure now if i could just get mine going

 

[KiamyDSM]

if theres shaft play and the housing is fine can i just replace the turbine. and that could fix the problem?

 

[MrBoxx]

If the seals are shot, then no, merely replacing the shaft won't do anything. You'll need to rebuild the turbo center section (new bearings, seals, etc) as well as replace the turbine shaft/wheel combo.

If the turbo is bad, just invest in the Evo III 16g. It's just not worth all the trouble to rebuild the stock turbo. Also, just how much smoke is it? Is it a small puff when it boosts? Is it a huge smoke screen at boost? Is it only a small bit at idle? What makes you think it's the turbo?

 

[91dsmgsx]

My 14b had shaft play and needed new turbines i took it apart and noticed that it was a little more work than i thought it was going to be to rebuild it, so i replaced it with a EVOIII big 16g. if you think you have the mechanical ability to re build the turbo go for it you would not only gain experence, you would also have the hands on knowledge on how turbos work inside and out and theres nothing wrong with learning something new about your car!
