Ok, I hope someone can help with this. I took my car out of the garage after sitting for about the last year. I have venom injectors,walbro, bigger to4e turbo,.... and more. I wasn't even on the gas much and it started puffing out white smoke, pulled over and I have fuel dumping down my exhaust. Any ideas, I heard that the venom injectors were bad, could that be it?

^ Correct. All depends on the temperature. For example Toyota service documentation specifically states white smoke is an indication of turbocharger problems. And how do you think air show performers generate that white smoke? It's done by injecting oil into the exhaust. These days it's an environment friendly formulation but prior to that run-of-the-mill motor oil was used...

I just thought they always were on the verge of engine failure but somehow would stay in the air.:sarcasm:

with that much fuel that I have going into the exhaust, can't the white smoke come from the fuel? Could it also, have anything to do with a valve thats stuck open. Is there any way to check the valves without tearing the motor apart? Keep in mind that this is a brand new built motor as well as a new Boss TO4E 61 turbo, so I have a hard time thinking that that is what is causing this, but ????

If you wanna check the valves and how they're seating with out tearing the motor down i would suggest performing a leak down test.

It has to be the fuel though, I can see it sitting in the muffler at times and it is somking white. I have no contaminents in the oil or coolant and both levels are staying fine. Just loosing fuel. I am going t o try the leak down test today. I have tryed swapping out t he computer, checked the injectors, swapped out the afm, and checked all fuel pump and injector sensors. Also the safcII seems to be reading normal and I checked all connections for it. I just think its weird that it's not throughing any codes????

If you can see it what does it smell like if its fuel you would really be able to smell it. And it would run very rough if an injector is dumping fuel into the cylinder, How does it run? My brother had a Venom fail and it dumped so much fuel it contaminated the oil.

Coolant burns white, oil burns blue, black smoke is too much fuel.

:thumbup:

Too much fuel can also give a gray/dark gray apperance.


You can see it pooling in your muffler, any wicked fireballs?? What does your WB have to say?

You sure its not coolant in your muffler...white smoke too eh?

water is a byproduct of the combustion process... its normal to have some liquid/vapor water in the exhaust.
the other explanation is that your burning coolant

I think it's my injectors. It is definatly fuel-it smells like it, evaporates pretty fast and the smoke coud be considered a gray. I am going to purchase a new set of injectors, swap out the plugs and change the oil and try again. Any recomendations as to which injectors to choose (550cc) that will use my existing wire plugs?

Venoms use the factory clips, Venoms are just bored out factory injectors Ive had great results from PTE injectors same plug as RCs you can get em of ebay for around 350$ Ive had two sets 680s and 550s,I flow tested both and the results on both were great.
Ive also used RCs which are also great injectors.

Heres the seller Ive used
