ok guys this has been bugging me for awhile the engine was rebuilt 2400 miles ago ever since i rebuilt it it blows smoke like crazy at warm up. it only does it when warming up. i notice if i plug the truck in at night it isnt near as bad. i noticed on the 90* days it isnt as bad as the 60* days. the truck drives perfectly normal and has plenty of power. dont have a clue what is going on also i did have the engine overboard like .1000 for oil would that have an effect on this?

 

Very likely your injectors


Wait until winter....

 

i know they smoked in the winter but it wasnt this bad last summer i know that for a fact, could it be because there is only 2400 miles on the engine?

its a pure white color smoke till it gets warmer then it turns to a blue shade then its gone. i have noticed if i let it idle at 2k when warming up once the water temp hits about 190 and the thermostat opens it is completely gone

 

Hmm, might get better when you get some more miles on it.

 

its bugging the hell out of me. its thick *** smoke for the first few mintues then i clears up. everytime i start the truck i let it idle at 1700-2k rpm till i drive it

 

how come i cant get video to load

 

I would look at my timing's effect on cold starts and evaluate my injectors. Generally blue / gray smoke is normally fuel smoke!

 

ok i held a lazer heat gun to the truck on the exhaust ports and the #3 exhaust port is on average 60* colder then the rest ao my guess is that the #3 injector is gunna need rebuilding

 

i replaced the injectors last night and the only difference they made were a power loss the smoke is still the same, any other thoughts

 

Weak compression??
