Lexus Blowing light grey to white smoke from the exhaust
Here's a question directed to all who might know the answer. Ive checked compression, all's good, no blow by. Ive disconnected the rad and drained all antifreeze. Is there any way that there could be a vacuum hose from auto box to intake somewhere, that sucking fluid?
All help will be appreciated.

Re: Lexus Blowing light grey to white smoke from the exhaust
As far I I can remember, you have just bought this vehicle. Have a chat to the previous owner if he had similar problems or was this perhaps the reason for selling it for a bargain price?
It seem that the head gasket has gone, do both while you are busy.

I did a compression test, and the engine runs way to well for a blown head gasket, also no oil in the radiator water either.

Re: Lexus Blowing light grey to white smoke from the exhaust
White / grey smoke means you're burning oil. Could be that you have a broken oil ring or they're just worn - could be that the valve stem seals are leaking. Does it happen under load or when running against compression? Under load will be rings, running against compression will be valve stem seals. Of course there are other possibilities like the crank-case breather pushing oil through the intake, but this will normally also be associated with worn rings creating excessive positive crank-case pressure - there could be a head crack at an inlet port and as mentioned there could be a head gasket problem between an oil gallery and cylinder.

Just to put an end to this post, it turned out after a lot deliberation, that it in fact was the fuel. I'm not sure what kind of crap was in that tank but it smoked like a chimney when i lit it. Thanks to Mud Dog for your input.

The smoke smelt weird. And the vehicle ran so well i really didn't think it was head gasket.

It actually smelt like an outboard motor when it ran, i cant think of any reason why it would be good for the motor.

Re: Lexus Blowing light grey to white smoke from the exhaust
Is your vehicle petrol or diesel? Sometimes the garage swop petrol into their empty diesel tanks and once you fill up with the contaminated petrol, your vehicle will give off a grey/whitish smoke. When that happened to my vehicle a couple of years back, I thought I had blown the motor. But the dealers checked and found that the petrol had traces of diesel in it.
Glad it is sorted out.

Re: Lexus Blowing light grey to white smoke from the exhaust
a little two stroke oil or diesel in the petrol won't cause any problems. Perhaps if you have catalytic converters it might be an issue. Glad you got to the bottom of it.
