Question *Pls look at this pic* smoking from turbo

It's an 05 WRX and it started smoking after getting up to temp. I see oil on the hotside area. Does anybody know what could the cause be?

That is right where the oil feed line is. The gaskets for that banjo bolt must have failed. Replace them and torque them to spec. That is where I would start.

if the banjo bolt is the one right on top with the little pipe running out of it, then that may be it. I just turned it on and saw oil dripping out of that bolt.

EDIT: i found a pic, oil it coming out from right under the bolt circled on the left.



Do i just get the OEM bolt and then remove and install and torque? What spec is it supposed to be? I have a vf39 if that makes a difference.

You don't need a new banjo bolt.
Appears you need NEW copper gaskets that go on either side of the banjo bolt.

Is / was the bolt loose? It may just need to be tightened.
I don't remember what size the copper gasket is, but you can pull one and take it to a good hardware store and buy new ones.

You can get the gaskets at your local Subaru dealer parts department.

The copper washers just need to fit the bolt.

If you get the bolt off and check the washer,
another possible source is Harbor Freight--

Possible, as I don't know the size of that bolt.

No. You just need the right size copper gasket to fit the bolt / fitting.
Not too big, not too small, but juuuusstt right

Hardware stores, auto part stores, Dealer

Could also use some Verneir calipers to get the OD and ID of the copper washer and then just order some from McMaster Carr. Thats the cheapest route and you can order more than you need so that you have extras

There is a thread over in the Brake section.
Someone posted a link to copper gaskets on Amazon.
Somewhere between $8 and $9 for 50 copper gaskets, all same size.
18 cents per gasket is pretty cheap.

You just need to know what size gasket you need.

Default *Pls look at this pic* smoking from turbo

other common smoke in the turbo area cause is the turbo drain back oil tube
as well as the power steering lines failing where they turn from rubber to steel line
Also valve cover gaskets like to leak onto the up pipe and smoke really a lot going on over there

You are going to have to clean up the area and look around for possible sources for your leak.
That includes reaching everything from both on top and below the motor.
Clean everything up as best you can, then run the car for a short period, or take car for a short run, and then re-check.

I HOPE you meant RUBBER, not river

Damn, I hate the automatic spell checker/corrector
