04 rx8 6 speed, car starts great and idles high (maf most likely, previous owner installed a k&n air filter with no screens in front of the sensor) once it reaches about 150 f itll start to smoke blue pretty moderately, ive tried revving it up to possibly clear some excess oil in the housing, but afterwards it idles pretty horribly, dropping to 500 then back up to 8/900. Again I think that may be the maf but I'm not sure. I also notice that the engine bay had a decent amount of smoke coming from itas well.

The car sat for over a year, a car lot i work for had someone do work on the car and after that they couldn't start it (they were flooding it every time they tried to start it).


l I've searched the forms for hours and cant find an issue like mine, ive also looked on google to no avail.

 

sounds like worn seals in your engine causing oil to leak into places it shouldnt

 

Or coolant. Mine stops when warm.

 

no

white = coolant
blue = oil
black = rich/unburnt fuel

 

well put sonicsdaman. You forgot red flames = cool.

 

sometimes my flames are blue

 

I was afraid that might be the response I got. Do y'all think it's time to rebuild the engine?

 

get a comp test to be sure. however we all know rennys are all blowed up pos. just put a fresh engine in every oil change or swap it for an isuzu v6

 

 

What if a car puts out blue smoke instead of white only when cold?
