Alright guys. I'm a newby so have to bare with me. I have a stage 3 saph running 385bhp had a build couple years ago hardly used, but it get creamy gunk in the breather kit "graham Goode" and it blows white smoke when let off the throttle after boost. Have you any ideas thanks.

 

Is the coolant level dropping?

 

No level is fine, oil is fine no misfire.

 

How bad is the white smoke.

 

Well I overtook my brother no smoke then he said it was when I let off it was a white puff. I can't notice it when driving?? Mysterious

 

Im sure sometimes cossies do this. I think its how there mapped. I can remember watching a few cossies at croft and silverstone and they were chucking out a small bit of smoke every now and then.

 

Cheers for response lads. I've also asked a few mates and they could suggest it could be over fuel?!?

 

Sometimes there mapped to squirt a bit of fuel in the bores to cool the pistons down when you come off the throttle. I could be wrong though. If you get no more replys I would phone one of the tuners.

 

Ok thank you mate. Appreciate it..

 

Fuel is usually black on the over run not white

 

I was told it could look a grey/white colour but not 100% sure

It does say blue smoke though...

 

the basics are:
black smoke - fuel
blue smoke - oil
white smoke - water

if it's got mayo in the breather system it might be water getting in somewhere rather than it just sitting around and it being condensation

fully clean out all the breather pipes and wash the breather out and give it an oil change and then take it for a good long run, not booting it just a run up and down a motorway or something to get it up to temp for an hour or so and then see what happens to it afterwards breatherwise

 

white smoke could still be from the turbo, it might be the water cooling side of it on the way out

 

I hear that a lot, and tbh I've never been able to work out how putting fuel into the cylinder, which let's face it will ignite and burn, can make it cooler than turning the injector off and pumping air through the cylinder.

To me its a waste of fuel, and is making more heat lol.

 

So its a load of shite then James?? But am I right about some cossies smoking a bit on over run???

 

also a lean mixture could create grey/white smoke, too....
A wideband lambda gauge will help you.

 

Ok thanks for the help, I'll dig a little further. Much appreciated.

 

So what does a bit of black smoke mean when booting the car but its only every now and then.

 

Yes your not booting it enough, it should be a flame

They are old cars mate, if your levels are fine then don't worry
