    the causc of this, the turbo blow and the engine jumped a tooth as i stoped the car and turned it off ,i then started it and turned it off again so i beleave i jumped then, so i agree its more likely to be vales seals.wold u agree.

If it's bluish it means tht it's burning engine oil, probabely the piston rings on this particular cylinder has gone it could even be the oil rings. It's better you take a compression test on all the cylinders you may find that the # 3 could be the lowest.
Maybe too tht the valves could be the culprit and the seals too on this particular cylinder.
Hope this helps!

    The bluish smoke is due to the turbo thn , it must have be allowing oil (thro the bearings of the turbo) into the combustion chamber via the inlet.

    The timming having jumped one tooth ..I guess it would not do so as the turbo has nothing to do wth the timming.

    The jumping of a tooth ..did it jump to ****** or advance? (Probabely it may have jumped from the T-Belt)

    After you telling me about the turbo, I think the valve seals should be ok. I reckon the oil from the turbo must have been gushing into the combustion chamber.

    Better is to replace the turbo and reset the timming and thn see whats the outcome.

I have a Nissan Murano when starting it up some days a small amount of white smoke come out the tailpipe for 1 sec . but the coolant is green an no oil on the ground mileage 187258

White smoke is a sign that coolant could be leaking into your pistons and getting burned. I doubt that is the case hear as you say it only happens for like a second. I would think what you're seeing is condensate getting burned out of the exhaust which is normal. If you think you have a blown gasket causing coolant to get into the pistons, go have your system pressure tested. If there is a small leak, it's better to take care of it now than to wait until it's really big and then the engine could get destroyed.

My vw t4 2.5tdi year 2000 van is a knightmare to start

look at the spark plugs an see if they look like the have chocolate milk on them. You may have a head gasket going out. White smoke is usually burning coolant. Also you can look at the uderside of the oil cap. a little chocolate milk look is ok, that's pretty normal for a cold climate a lot is not a good sign.

Smoke problem

there are couple of smoke smoke is oil, black smoke is fuel, and white smoke is water, if it clears after starting and running a few minutes it's probably your valve guide seals leaking oil down on top of your pistons, causing it to smoke until burned off and foul your plugs.
