Yeah Right...You are the tuning expert.....

The meare addition of a marine gasket will not cause the truck to smoke white,sorry.

Explain to me what compression he lost by the addition of the marine gasket?.If the job was correctly and the head was torqued properly when a compression check was done then you would have the same amount of ft lbs of pressure on your compression gauge.A compression gauge does not read or determine what your compression ratio is,it just simply tells you if you have the proper pressure in the cylinder.If the cylinder is sealed then no matter what thickness of material the gasket is the compression reading(pressure) will remain the same.

 

not burning oil, coolant temp. is fine, not blue or grey smoke, and not losing compression...just white smoke when i let off throttle going downhill and usually when cold or 10-15 min after start-up.

 

leaky injector? i know i said i was backing out of this one... but; if the integrity of the fuel system is ok it sounds like a faulty injector

 

replaced injectors all is better.....thats for all the info guys!
