This usually indicates that the engine has a leaking head gasket. Do not run the engine with this problem, it will damage the cylinder head(s).

    I have seen head gaskets leak leaking and the engine is not overheating, the gaskets leak due to age and electrolysis of the head and gasket. You do have coolant getting into the cylinders of that I'm 99% sure.

I have a LS400 Lexus thats will start then immediately dies, I've checked fuel pressure and have 40psi, it is not pulling any codes, has new battery, any suggestions?


Hello,

Does the vehicle rev up to about 2k RPM and then die? Does it do this every time, meaning can you start the vehicle every time but then dies?
Was there any other things happening before or several different things? Example - black smoke out tail pipe, would not hold a steady speed and jerked or hesitated? If you answered yes to these questions it is a good chance the vehicle computer needs replacing. (I had the same issue, different vehicle).

If not, do you have any more information?

I hope this helps!!!

I have a 95 ls400 lexus when I start the car white smoke cloud then for about 3 to 5min after. No smoke! no smoke when on gas or on stop no overheat rides fine


Is the engine running bad or "misfiring" when it is doing this? It sounds like the beginning of a serious head gasket problem. Or it could just be time for some valve seals. Is the check engine light coming on? I would recommend having it checked by an experienced auto repair technician to avoid possible severe engine damage.

Whenever I start the car it smokes than after warming up it stops smoking.


The key is how much smoke? Does the smoke have a smell to it. Are you consuming any fluids, like coolant, or oil?

Tons White smoke that is sweet smelling is usually coolant getting into the combustion chamber.

Less white smoke, especially if other cars are doing it, is normal. For every gallon of gas that you burn, you generate a gallon (GALLON) of water. so this water usually evaporates, but sometimes not. It has little or no smell.

If the smoke is bluish white, that is oil, but usually your converter would fill with oil, and cause error codes, or loss of power. This smell is distinct, but not necessarily sweet.... After the converter heats up, it may be able to burn off the oil and the smoke stops.

What are you consuming, fluid wise, will direct where you go next.

I had a new water pump and timing belt put on my 1991 lexus ls400, but i see white smoke coming from the tailpipe and when i put coolant in the reserve tank it leaks out but not on the ground. Can someone...


could be the head gasket gone, if you take it to a garage they can do a test on it which will take about 10 minutes, if you are leaking water but not on the floor there is a good chance its going into the exhaust which will cause steam(white smoke) out the exhaust

Blown Lexus ls400 engine


Smoke is a sign of engine burning oil, which is caused by faulty piston rings, in most cases it's cheaper to have another engine installed in the car, instead of having work done on pistons. Hope this helps and please rate the answer if it was helpful, it helps me, thanks! P.S. Comment if you need more advice, it'll be my pleasure to assist you.
