Fuel Problem

1992 Lexus replaced engine (80,000 miles) everything was fine but all of a sudden it started poaring white smoke out the exhaust and using alot of fuel. Went 40 miles and car used $10.00 of gas. When sitting idle, white smoke is coming from exhaust with a raw fuel smell. Replaced one fuel injector, spark plug has to much fuel on it. What would cause this to happen? Engine is running smoothly but dumping fuel.

You severly blew a head gasket & the car went in limp mode.
Have a compression, or cylinder leak-down test done on each cylinder.


Be sure to write down the results of each cylinder.
