Early signs of a problem? puff of smoke

I've never had any sign of smoke from the car, despite 31/2 years of BPU, but tonight driving home I was coasting in D down a hill, knocked OD off and thought I saw a quick puff of smoke out the back. I then knocked it into 2 and am positive I saw a bigger puff. drove the final 5 mins home knocking it between 2 and D with the odd burst on boost then off then back on throttle, but didn't get any more.

 

Got home and checked for smoke on idle, but nothing, so went for a 10 min drive and tried to recreate it down the same hill at the same speed etc, but nothing. I let the car cool down and went out again. No smoke on start up or idle and couldn't get it to do it again.

 

Any ideas??

Ive had this a couple of times. I filled a car park up with smoke once at a meet! Never done it since. Get the smallest of puffs come out the back every once in a while so im told but nothing to loose sleep over.

I think you're right. Can't do anything about it anyway, so I guess I'll just monitor it and see if turns into something nasty. Maybe a bit of crap petrol, as I'd just filled up and gone form V-Power to Esso 97 (Shell garage on the ring road seems to have changed hands overnight :blink:)

check your oil level aswel just to make sure its not to high.

 

Did that and it seemed OK, but will give it another check tomorrow (away tonight) so it will have plenty of time to drain back into the sump - maybe it's a bit overfull and needs some removing. Where you get your syringe?

Any syringe will do, cant remember where i got mine but a bigger one if i have to do it again. Any thing that will suck oil out via a tube really.;)
