started her last night, and loads of dark grey smoke until it had got warm, thought nothing of it, but exactly the same this morning - once warm its fine, any suggestions..?

Azrael

Does it smell oil or petrol?

Dave Henshall

petrol,

but it dos seem to be using a lot of oil lately, if the turbo seals were passing , would the smoke be blue or grey until it was hot? no smoke on boost though

Azrael

If turbo was leaking very badly it could be light grey smoke. Not blue as normally.

Try giving it some loud pedal and then stop and let it idle for some time - check if it smokes then.



It can smell petrol a bit after starting, mine does. But this can be of course also a sensor failure and overfueling.

Dave Henshall

bl00dy cossies, its literally one thing after another,

Azrael

I can understand what you mean. Still they are nice cars, you just need to live down the corner from MSD

rapidcossie

poss the temperature sensor (blue) as mine did that til i changed it, smoke was black tho(fuel)

Dave Henshall

only when cold though, i would have thought it would do this all the time (assuming it had failed indicating a cold engine) ?

rapidcossie

i think the sensor thought the engine was always cold as it only cut out after maybe 5 mins, it used to over fuel hence the smoke.

Dave Henshall

yeh yeh, i understand that, but mine warms up normally then the smoke clears, surely if the sensor had failed it would smoke all the time..?

the sensro is there to MAKE it overfuel when colde to get it running and warmed up properly,


just ben for another drive and tried leaving it idleing then floor it, and no smoke (only a tiny whiff) and no smoke on overrun or on boost.

will see how it is in the morning again.

just out of interest , how much is a recon T34 nowerdays..?

If the turbo seals fail on the rear of the turbo, it could be leaking into the exhaust which makes it vapourise rather than burn......

They can be reconned for as little as Ł250 but I wouldn't expect it to last long for that money...

Dave Henshall

today again, a bit warmer than the other day and again no smoke ?

could the compensation for extra fuel when cold be too much when OAT is <10 dgc..?

Dave Henshall

could it loose a fair amount of oil this way and not produce a lot of smoke.....?

Azrael

When it leaks REALLY badly sometimes it only smokes when idling for long periods. Mine did that. When driving there was almost no smoke.

Dave Henshall

stu did comment when setting it up that the turbo was worn, not knackered, just quite worn and would bennefit from a recon one,, perhaps now is the time, the extra boost has maybe finished it off

Azrael

Still what you describe just not seam like turbo.

Did you ask somebody to drive behind you and look for the smoke?

Dave Henshall

not yet, nobody can keep up

Azrael

I had my mechanic drive behind me in Kadett 1.8 Automatic and he kept up

Dave Henshall

seriously, though, not yet, the only thing i can see when its cold it the look of disgust on other people faces when i set off " look at that horrble boy racer car with a knackered engine smoking away "

Azrael

I would really like to help you but it's hard to know what it is without seeing it. Probably removing downpipe and looking throught engine error codes/logs will tell everything but you need a pro for that I suppose.
