i got a 1994 LS400, and when i turn it on it shoots out a lot of white exhaust fumes. When i rev the car at higher RPMs its shoot a lot more white exhaust fumes. Any ideas to what this can be caused me by? There are about 87 000 miles on it!

from the engine water jacket cooling system.

Does your white exhaust fume go away after the engine/exhaust system reached operating temperature?
If it doesn't, you have a problem.

Mine have when the engine is cold but after 10-30 seconds it gone. The dealer said that it is normal so check your car whether it happens for just 10-1mins or all the time. If it is all the time then you have the problem. Let us know ok

no its just started happening like this much, before its jus becuase the car wasnt warm

i thought it would be because i was low on oil and i checked and i was, im changin it tomorrow hopefully that will solve my problem!

Maybe you have an oil leak and the oil are left on the exhuast so when you start the car, the oil start to burn. It is common for the car this age and especially Toyota or Lexus. My friend has a 97 Camry and after 60000k, it start to smoke when the car is cold. It is the same another friend 1994 GS300 with 135000k. The dealer said it is normal!!!

Smoke from burned oil is usually bluish.
Smoke from burned oil leaking from valve cover gasket onto exhaust system while the engine is running will leave the engine compartment with a strong oily odor.
