im workin on a pontiac trans sport van,

just put new fender on it, new bumper, new axles, etc.. was in a wreck.

everything works now and it runs strong but smokes... what would be the cause of this? should i change all the oil out and put a new filter on?

any help appreciated, also the battery seems dead but i jumped it and it came right on, shold i just let the engine run for a while?

 

smokes on start up only, or still while running?

what color is the smoke?

 

if it smokes all the time your burning oil or your piston rings are screwed.

 

it smokes when i start it but i notice every once in a while while its running a little comes out, it has sat for a long time tho

oh and i forget i think its similar to the smoke in ur sig - just not from peelin

 

if it smokes on start up its most likely valve seals or valve guides

and the smoke in my sig looks more bluish, therefore its oil and not just carbon or anything else

so its either what I said or Pdubinator, but like he stated its more if its doing it all the time


do a compression test, and a leak down. that will be able to differentiate much better than our guesses online, and what color the smoke might look ya know what i mean

 

yea thanks man i was just tryin to get a quick answer on it, you guys helped me out if i have any other questions ill post it here
