I'm guessing this is a fueling issue, I thought at first it was blue, but it's not, just grey puffs of smoke from cold startup and occasionally when it's been left for an hour or two.

 

I'm still running a Jap ECU.

Anyone?

Anyone?

 

 

condensation FACT

Has got a blue haze to it on further inspection. Only does it when it feels like it....PCV valves probably, judging by its oil dumping episode the day after I bought it! LOL

I nearly always let mine run for about 5 mins in the morning before i head to work, and theres always a lot of grey/blue smoke before I head off. But then its fine, not so much as a puff on acceleration or normal driving. Dunno if that's any help

I had a big issue with this and had to replace my turbs and pcv valves which helped. But now and again after about 10mins on warmup i get the odd bit of grey/blue smoke, so i reckon i must have a leak somewhere, bl@@dy nightmare!

Mine does it instantly on startup for about 5 seconds. Does it no other times and does it intermitantly. So nothing serious.

howmany miles it done??

60k, but it is intermittant. Started it up this morning and the exhaust was as clear as a whistle.

ah well shouldnt be much to worry about then i wouldnt think ;)
