Sorry about the placement, and thanks, it had me a lil nervous since id never noticed it beforeJust a little rich right there and by the looks of the edge of the exhaust outlet it has been that way for a while. Who tuned it? What year is it?( ok,see it's an '04 STi) And wrong forum moving to ?
^^This.How's the oil consumption?
no its not wet, its more powdery, and only does it on startup and stops onces it warms up^^This.
Is it wet when it comes out? Catted or catless? When my #4 piston was going out it spat out tons of wet oily black stuff out the tailpipe. That said I've seen plenty of cars that blow black carbon type crap all over the rear bumper. Not sure if it a tune issue (rich?) Or something more serious.
I ran into a similar problem at the track...no its not wet, its more powdery, and only does it on startup and stops onces it warms up
i mean i dont drive it easy, but i dont beat on it non stop, i get on it every so often, and occaisionally do highway pulls but im not too bad on it, and mine isnt smoking though, so i believe our problems are unrelated because whats coming out of my exhaust is not oilI ran into a similar problem at the track...
Ran a 10min session on a short track (6 turns, 45sec lap, literally beating the car...), then stopped for a couple of minutes, running at idle. When i got back in, i gave it some gas in neutral and this rather big puff of blue smoke came out. Ran a few cooldown laps, no smoke. Came back to paddock, let idle, then gave gas at idle, smoke again, but less... so i went home. no smoke. start the car 5 hours later, smoke again, and i noticed black liquid soot on the bottom of my exhaust tips. Start up the next day, little smoke... next day, none, and all is well today too after 200kms of driving. No power loss, no check engine light, no-thing. So I'm guessing I pushed the car too hard, and squeezed oil past a seal either turbo or valve or ring or whatever. So when shut down, the oil would "drop" back somehow into the exhaust line to come out the back. The oil finally was all gone so that's why it's not smoking anymore... Brand new oil btw, and the level is fine at the top.
Frankly, I was worried but now i'm not... but i do worry for your engine though.. black specs like that can't be good. You're prolly cooking oil somewhere, or oil is going places where it shouldn't... Compression and leakdown would be in order, and check the turbo for wear. I'm no mechanic, but that's simply not normal.
Can you give us more info, like how often do you drive it? Do you drive it hard?
Cooked oil with carbon..... could be..i mean i dont drive it easy, but i dont beat on it non stop, i get on it every so often, and occaisionally do highway pulls but im not too bad on it, and mine isnt smoking though, so i believe our problems are unrelated because whats coming out of my exhaust is not oil
