recently my civic started to blow a white smoke that smells of fuel, the headgasket is not blown. For the first 10 or so seconds at cold and hot startup there is no smoke, then it smokes. It looks like the steam you see on a cold day at cold startup but does not smell of coolant only of exhaust and raw fuel, also at warm idle this steam/smoke occurs aswell driving with wot. I have checked the computer and it says:

coolant temp

TPS

Intake Air Temp

Fuel injector

I am lost as too if i should replace all of these or if one will solve my issue. I am thinking it just may be stuck in warmup cycle?

any positive input is greatly appreatiated.

white smoke is always an indicator of a coolant leak.....blue-oil, black-fuel....

Keep an eye on the coolant level and see if it drops. G/L

You're saying those are the codes you got right? If I were gonna be choosing between those which ones I'd fix first I'd start with injector and TPS.....personally I'd go after all of them though.

coolant level has not dropped and temperature is normal, the Tps... any idea how to remove, i searched with little luck? thanks, j

also coolant leak? i did my HG approx. 1500kms ago, what about the small coolant lines on the intake mani? Should i just take it right off and see if its coming in through one of the ports?

Okay i had a simular issue with the smoke. To me it seemed like white smoke but in fact had a light blue to it. Car drove fine with no issues at all. Only smoked at idel amd wot. ... so i asked a friend and he just seen it and gave it gas. What he told me was "its your rings, if it only smoked during idel it would be you valve seals but sinice it smokes at idel and wot its ur oil rings. They are shot out and needs replacing."
So i bought new rings, rod bearings, and new head gasket. I toook out the pistons and oil was getting through! I changed everthing and no more smoke! Hope this helps bro

solved issue, the idle control valve on the intake manifold ,which has coolant running to it, had a small crack allowing water to seep into the manifold


thanks for all the input
