White Smoke from the exhaust

fitzgese · 03-04-2007 5:21pm #1

Was having a look at car today (Nissan Primera 1.6 Petrol 1998), and noticed a lot of white smoke coming from the exhaust, even after the car had been left idling for 15-20 mins. There was also water (or maybe unused petrol, but I think it's water) coming out of the exhaust. When revved, a lot more white smoke came out. Does this mean there is something wrong with the head gasket, or could it be something else?

Keep well away from it its burning oil, head gasket probably on the way out. Im not a mechanic but they will offer similar advise.

If its a lingering whitey blue smoke with a bad smell, it could mean burning oil, ie rings or valve seals gone. A garage would know immediatly with a smog tester, also check your oil level. If it was that it would be an instant nct failure.

I thought blue smoke was bruning oil, i.e. wring rings? White smoke is a head gasket???

Blue smoke = burning oil
White smoke = water
Black smoke = dirty diesels

Had the car been sitting up for a long time? Its not uncommon for moisture to buildup in the oil if it had been sitting for weeks/months. A good long drive letting the oil heat up fully should clear it... on the other hand it could be head gaske problems. Check for the usual signs like white gunk in the oil/ black gunk in the coolant.

I doubt it's white 'smoke'. It's more likely to be steam. As others have pointed out, this indicative of a failed head gasket. My advice is to get it checked as soon as possible before it leaves you stranded - not to mention the extra cost involved in repairing a toasted engine.

It's more than likely the Head Gasket, in 90% of cases I've seen, white smoke either indicates a Pope has been chosen, or the Gasket's a gonner.
