d15b8, if i gun it in first or second, smoke comes out the exhaust, looks to be blueish/white

 

Blue smoke = burning oil, White smoke = burning coolant.

 

and black smoke means burning fuel

 

running rich i mean, 2 much fuel

 

White = coolant
Blueish= oil
black = rich or soot of carbon buildup in exhaust pipes (from running rich at one point)

 

dont forget the sweet smell also means coolant. 90% of the time the white smoke will leave a sweet scent.

 

how do u prevent from running rich or stopped from running rich?

 

depends on WHY its running rich in the first place. if its due to o2 sensor, you should replace the o2. if its ignition problem where its not igniting your fuel right, fix your ignition problem. if its larger injectors, get it tuned. etc etc etc etc

 

o ok ok.....i did have my check engine light on and it was reading o2 sensor but then after about 3-4 days it reset and the check engine light went off. so it might b the o2. but y would the computer reset wit out me reseting it by hand

 

I have the same issue with my car. The car was re-built but I did not know there was extensive work to be done.

P&P head and stock block that was rebuilt. The car burns about a quart every 900 miles or so.. There is noticeable black carbon/oil deposits shooting out of the exhaust and stuck on the back of my car.

Would that be because oil is passing through the engine due to egg shaped cylinder walls?

Sorry to jack the thread, having some issues as well....

BUMP!!!

 

yes sir.. you should do a compression/leak down test. check your numbers to really see what is going on. the smoke signs is just to let you know whatsup

 

who should do the check??
