Don't really know if there's anything wrong or not but when I push the car hard it lets out smoke from the exhaust. Say something like when I drop it a gear and rev it to, say 5,500 RPM. It's not really drastic like you can't see other cars behind you or like a smoke screen from 007's car, it's very light and faint.

I didn't notice it but my friend mentioned it this morning when he was following me. He also said there was a strong smell coming from the car as well.

Am I just paranoid? Or is there something really wrong with it? I think decatting the exhaust has something to do with it and maybe the smell's coming from running SUL?

I know from previous experience when a car starts smoking it generally means the turbo's on it's way out but my car's only done 9000 miles!

I do look after my baby, I start it up in the mornings and let it warm up and don't really abuse it and I let it cool down before I switch it off.

This has got me really worried now and want to get to the bottom of this. Help!

Gordon,

Ask you friend, what colour the smoke was. If it's black, which is most likely for a scoob, the car is running rich which is normal and when you give it some stick they all blow a little. If it was blue it's burning oil. If it was white or sort of white, (not to be mixed up with the cold start up steam or vapour) which is unlikely for a scoob, it's running lean.

Cheers,

Wrexy.

Gordon, did you ever find out what caused it?

My saph cossie used to belch brown smoke (lots of it) - needed mew head gasket and skim - £1500 costs...

Funny you should say that. I've started using Optimax lately and ever since I've been using it, there's no smoke! Strange...........

Well after this length of time, if there was a problem ,it would have shown up by now.

Cheers,

OK, some more testing last night.

It seems to occur when I hold revs at about 3k, then boot it. Regardless of whether I change gear or keep going I get the "pop-pop-bang" and smoke about 4/5k.

Sounds like a mis-fire... ?

Brown smoke is a sign of a well tuned motor, under full power.

OK sweet, think I sorted it. I have this issue with boost in first gear from about 5,000rpm onwards, kind of an extra kick (Ever since I replaced the standard exhaust with the 2.5 full system). Thought it might be overboost so did the old brakecleaner-in-the-boost-solenoid trick... didn't seem to work, and then this issue.

Took it apart again, sprayed more in this time, and bingo. All good...

Cheers guys

(P.S. possibly it was back-firing/mis-firing, and cleaning out the exhaust, hence the brown smoke. Sound feasible?)

What about brown smoke?

Just tonight for the first time, come out of a roundabout, give it **** in 2nd gear and upon release of the throttle for the change to 3rd, "POP" and all this brown smoke is left drifting in the air behind me.

Didn't believe it could possibly be my car, so did it again and yep, sure is. More of a "pop-pop-crackle-pop" and HEAPS of brown stuff shot out of the exhaust and is just hovering in the air. Got home, car didn't smell much worse than normal.

Any ideas?

P.S. MY95 WRX - 130,000kms, full 2.5inch exhaust, ITG panel filter, oil change about 1/2,000kms ago.

P.P.S. Found the thread from a search, hope you don't mind ressurection.
