blass001 Posted February 17, 2011 Share Posted February 17, 2011 Hi everyone! I have a 90' legacy with a ej22 engine. Lately i noticed that white smoke is coming out the exhaust. Is not noticeable when you run it but when stopped is a abnormal amount of smoke. is obvious at night. I change the motor oil to Amsoil to see if it helped, since white smoke usually means that is mixing oil and gas. Same problem so far no improvement. If anyone can help tell me the different options of what the problem could be and if possible how to fix it?? Thank you Quote Link to comment Share on other sites More sharing options...
MilesFox Posted February 17, 2011 Share Posted February 17, 2011 Automatic trans? sometimes when a modulator fails, it will suck ATF thru the vacuum causing a thick white smoke. Quote Link to comment Share on other sites More sharing options...
Rooster2 Posted February 17, 2011 Share Posted February 17, 2011 White smoke could indicate that a head gasket is bad, allowing coolant to enter the combustion chamber, and exit as steam from the exhaust. Check your radiator to see if the water/coolant is a little low. Don't think that the white smoke is oil and gas. If that were to occur, the color would be darker, and more blueish in color.

SoobrDad02 Posted February 18, 2011 Share Posted February 18, 2011 If you can let it idle in park and get a whiff of the smoke, you'll be able to tell if it's coolant by the slightly sweet smell. Quote Link to comment Share on other sites More sharing options...
