okay im pretty sure i have bad head gaskets or injector cups. i am looking to my brothers for HELP!!! so every time i start my truck cold after sitting over night or extended periods i start to get a rough idle like a lopey idle then i start to puff white smoke at idle this all happens about 15 seconds after i start it. then i go to drive away and i pour white smoke pretty good out the pipe for about 2 miles then it goes away and doesnt come back. i am losing coolant about a quart a week, but my oil is not going up and doesnt smell like fuel. also noticed that in the morning my upper radiator hose is rock rard with pressure and when i take my expansion tank cap off it lets pressue out, after sitting over night. wierd thing is my gas mileage is going up, go figure.

everybody says engine's run the best right before they blow.... :eek:

hope you get the problem fixed economically as possible. keep us posted.

I would do a tear down and replace the head gaskets.

Mine did the same thing. Diagnosed with 3 of 8 injectors bad.

Headgasket? Injector cup?

Jason86,

Take it for a short ride after it has sat all night...pull over and shut down. Slowly open the coolant reservoir...if you get a huge hissing sound...probably your headgaskets. Mine acted the very same way when my headgasket went....but I noticed coolant reservoir was always low besides the smoke first thing.

When my injects went...she smoked anytime decelerating and at a stop. It never went away like the headgasket...once the motor warmed up.

Good Luck,

Wayne
