When putting my foot down am getting a puff of white smoke which I assume is coolant however I've checked the coolant level and it seems to be normal.
It only seems to happen under full boost.

E.g driving along slowly and then planting my foot down puff of smoke under heavy load. However once am up to speed theres no issues?

 

coolant is white smoke mate, oil is blue and unburnt fuel is black,.

What car and mods Juggers?

 

Sorry meant coolant

My new track toy MY05 JDM STI remap, turbo back exhaust and an SC42 twinscroll.

I've been told I may have a leaking injector or a bust turbo seal?

 

Is the smoke constantly there or does it get less the more you drive as it could just be condensation in the exhaust given the time of year?

 

can still get white smoke with turbo giving up, best way to check is leaving it idling for a bit then give it a good rev.

If the car is stationary and I rev the **** of it theres no white smoke.
It only does it on full boost under heavy load a big puff of white smoke covers the rear wind screen and then it clears up and is fine after 1st and 2nd gear.

Have tried this.......turbo is a new unit however someone has suggested a seal is this possible?

Thanks for all the help guys on new years days

 

It's certainly can't be counted out that it's the turbo but unlikely.
You have to remember that the heat an exhaust will see is worlds apart when stood still reving to when being driven under load up the road,if you haven't already I would take it for a good long drive ie 50+ miles and see if the smoke is still there,if so I would looking to take the down pipe of to see if there is any signs of water/oil there.

 

Cheers for the advice mate much appreciated

Will get it looked at next week

 

Id suggest its just rich as it spools up especially as its been mapped. Mine does it if i gun it from low revs. Has done for the last 8 years. I was speaking to Simon (jgm) about it some while ago and his is the same

 

rich would mean black smoke would it not??

 

Unburnt fuel is also white. (eg: hot exhaust and not enough spark energy - i.e flooded)

But you have to dump a serious amount into the exhaust for that to happen (like what Classic scoobs do on a winter cold start).

Its only black smoke through combustion with a lack of air (rich but good spark - not flooded).

It is quite dense though, denser than steam, but not as dense as oil smoke, and if you sniff the tail pipe, it'll stink of petrol.

 

The above comments do sound similar apart from the petrol smell.
The car has a slight hesitation as tho theres sh't load of fuel being dumped in.
