Default Smoke from the muffler

Bought a 02 WRX with 160k but the block itself was from a car with 60k. Iím not losing oil and I think the turbo is seal is going it does have 160k on it. Does this happen often and is there any quick remedies I can do to prolong the life of the turbo til I can get a new one? My accesport says Iím still getting full boost but the amount of smoke worries me, I donít want to blow the engine or anything. I have a mechanic willing to do the work once I get the turbo but I canít seem to find one at a reasonable price anywhere.

The only way to fix a leaking turbo is to rebuild or replace. If you can't do either soon, then just keep an eye on your oil levels, which is good advice regardless.

I'm interested in the response you get as well. What mods/turbo do you have?
I have an sti swap bugeye with a Dom 3.0 and I blow tons of smoke but my turbos old with bad seals. Keep checking your coolant/oil. My block only has 3k but the turbo has at least 50k. I burn some oil.

I just bought the car recently. I know it has a full invidia catless exhaust, some kind of aftermarket intake, accesport stage 2 on 93 octane and an STI down pipe. Thatís what I can think of off the top of my head. I bought if from my cousin for $1,200 so I got a great deal. Other than the turbo one of axel seals is leaking which Iím fixing next weekend and a little body damage (New England Weather).

Agreed. Keep watch on fluids, at LEAST once a tank of gas, more is better!

Major red flag, CATless DP, I am not aware of ANYONE that has an OTS CATless map.
Nobody!
Intakes, COBB OTS maps only support some aftermarket intakes. Anything else, who knows what you get.

Since you are running an AP, read the mapnotes, match parts and fuel exactly!
Or, get a ProTune.

While I am not really a FI Subaru guy, I have been dealing with COBB since the AccessECU days (pull your ECU, list year, model, mods.....ship ECU to COBB, wait for it to come back).

Idk if this looks familiar but this is a pic of whatís on it for an intake. I know nothing about Subaruís as you can tell.

The red bit is a silicone turbo inlet, which you want because the factory one is known to rip at the turbo end, causing intake leak. You can check that job off your list as it's been done for you. There's no real performance benefit, as far as hp goes, aside from the fact that it'll last to help you perform.

To add to that, the intake that Charlie is referring to is the part the MAF sits. See pic.

Intake is in red (box and the s-bend tube). MAF is in yellow.

Agreed, the red ribbed bit, I believe, is a turbo inlet hose......no tune required AFAIK.
Yes, per viper_crazy picture, changing to a CAI or short ram (which replaces at least the big plastic filter box) DOES need a tune.

That is all 100% correct.

leak-down and compression test it if its new to you for sure a recommended thing maybe coolant finding its way out the back

whats your local temp my build with less then 8000 miles on it precipitates when its below 55 almost always also full cat-less

also looks like your missing a timing cover there not sure if it was just at that picture but you should really make sure you have one on there

^This. What's the weather been like lately? Something I usually take for granted as I live north of the 49 @ ~3,500 feet elevation. Been down to 32 degrees lately.

Are you certain it's the turbo? I have 210,000 on my 04 wrx, stage 2 tune, catless, etc etc I burn a quart of oil for 2 fuel tanks. The think smokes like a james bond smoke screen at idle and sometimes when I get hard on it.
My turbo isnt bad however. No excess oil in the turbine or impeller. I have 3 bad valve seals that are causing my smoking. I noticed them at 195k when I did the head gaskets. Have a nice oily buildup on the intake stems only
When I did them unfortunately I didnt have the spring tool to do it then. I'm just now getting around to it.

I live in Connecticut so it ranges, since I owned the car it was around 60-80 but itís at around 50-60 during the day now. I can smell oil burning sometime while Iím driving and at idle pretty much always.

I have the cover I just havenít had a chance to put it one with work being so crazy right now, I work in the pool business so people are closing their pools now so Iím super busy but anyways yeah.

Temp is anywhere from 50-70 daytime in Connecticut.
