I have a 2004 WRX and its smoking blue from the tail pipe(oil).. I was wondering if i can get a 2nd oppinion about the issue on here. here is what happens:

 

Start car normally: no smoke

 

drive car normally: smoke at stop once car is warmed up (not all the time) reving the motor causes more smoke when the issue is present. However after a couple of quick revs the smoke has stopped (at least visibly)

 

drive car hard: same as above but with more smoke. at first this only happened on occasion, but now it is everytime i let the car idle at stop (or run on the TT).

 

My assumption is bad seals on the turbo. I have not taken it apart yet, and it is covered by warranty (lets see how that goes). Only other 2 things i could think of are vavle seals (dunno if this would apply since this is an H4), or <gulp> piston rings.

 

Car has a 3" exhaust, but no EM or boost controllers besides stock. the only thing i have done differently is the switch from M1 15-50 to Amsoil 20-50 (and this last one was Amsoil 10-40 for winter).

 

any ideas would help. i have already found another turbo, but an engine will not be easy (providing the dealership does not want to fix)

 

thanks in advance,

Joe

<<any ideas would help. i have already found another turbo, but an engine will not be easy (providing the dealership does not want to fix)>>

 

why do you think the dealership wouldn't fix it? its still under warranty right? i would just take it to them and have it fixed instead of getting "advise" here and trying to fix it yourself.

If I remember correctly, Subaru's have a modulator valve. These can fail and cause the engine to burn off the tranny fluid. I know that they had/have them on the older models, not sure if they carried over to the current models.

 

BTW: Auto Transmission's only. Manual's don't have it..

 

If I am wrong, I know that someone will correct ...

I don't want to go though that again.

 

Besides, it may entitle me to upgrade (though the wife) but don't want to upgrade the wrong parts that would suck. Plus i want to guesstimate what costs will be if any problems arise from the stealership.

Tranny is manual, which would be white smoke. already checked for a leaking tranny though, but unfortuantly it is coming though the exhaust pipe. also i have checked the oil filler cap which does not show any smoke like the tail pipe.

thanks for the suggestion though.

Seals? I doubt it. One of the shortcomings of gas engines fitted with turbos is that the engine can be shut down before the turbo has settled down thus killing the oil pressure that the turbin shaft rides on. The result is a scored shaft that bleeds engine oil into the exhaust side of the turbo, and hence the smoke. Don't even try to fix a turbo unit yourself or it will probably granade on you. Not pritty. Get a factory rebuilt unit warranty or not.

There's a thread there about ring landings breaking. That much blue smoke under those conditions says "Rings" to me.

I thought the oil would overheat and coke up the shaft causing premature bearing wear? either way i have had a TT on almost the whole time. its not my first turbo car, but it is (if it is ) my first turbo failure.

 

So, does my deducive reasoning sound right about the turbo?

**UPDATE**

 

changed back to 20-50 for over 5k miles and problem has not returned. stuck with amsoil just moved from the 10-40.

 

conclusion: bad seals on turbo or to thin of an oil.

p.s. thanks for all your help on this issue
