I just installed 30# injectors and my new pcm from madwolf and i'm getting a little white smoke. I wasn't getting this prior to the new injectors or pcm. car runs fine, no misses etc.. exhaust doesn't have a sweet smell to it. also it is kinda chilly out but anyone have any ideas why it I would have white smoke after the injector swap?

 

white sweet smelling smoke is coolant, unless you have puddles of coolant on your intake that drained into the engine with the injectors out i cant see how the 2 are related.

 

I couldn't tell ya, I just checked my oil and it looks fine, not milky. The smoke doesn't smell sweet at all. it's not thick or billowing or lingers. argh, I hate this.

 

Were the injectors new or used? Maybe they were treated with some cleaning chemical on the tips to prevent build up. Like when you go into a service for injector cleaner how all the smoke comes out the exhaust after they install that chemical treatment.

did you drop a can of seafoam in there?


black smoke is fuel, the one i would expect to see if you installed injectors that are too big.

 

not yet anyway, but I did find that the pcv tube on the passenger side valve cover was disconected and there is an exhaust leak before the 02 sensor. I connected the tube back and it only smokes a very little now.
