blueish smoke

[SKnapp]

I noticed today on my brothers 93 that when he stood on it hard it was blowing blue smoke. could this be a faulty injector?

 

[therabbittree]

was it fully warmed up?. . and what injectors is he running ?. . the pods might do that normally. . the truck will probably blow some blue when its not warm too. . and of course it could be a fuel injector . . hopefully its not oil. . does he let it run idling for along periods of time ie 10mins and more?. .

let us

know more infor

thanks

hi it was driven a few miles before i saw it. stock injectors, he did coment that the truck runs awful cool. doesn't blow much heat even going down road. i had a 92 before my 97 and it was never like that.

 

[therabbittree]

maybe its just a thermostat. . cold running will get some blue smoke etc...

thanks for the input i will have him change it out.

I've always thought the following:



Blue smoke = oil

White smoke = coolant

Black smoke = diesel

 

[therabbittree]

That is relative. the blue can be fuel or oil . the white could be cold temps, a blown turbo or a headgasket ha. . and black is fuel for sure.

later
