exactly,too much timing,or too little timing,could result in unburnt fuel.

 

More timing with that setup you should be at like 18 maybe 20

 

unburnt fuel=Black..white=water..blue=oil..grey=fuel w/water..water meth usually makes it lighter..how does changing the timing affect how black the smoke is? i would just figure it would change how much black smoke..more or less fuel burned??

 

to a point its black but if your timing is far enough off itll blow white white is raw fuel it doesnt even smell like smoke if its a little off itll get hot and be grey

 

i would say that black is fuel that is not completly burnt,but white is raw unburnt fuel.it'll burn your eyes.and as tater said if it has water in it,it willl have a grey look to it.

 

when you say grey is it "hazing grey?" or is it large amounts of grey? if its just a haze its getting pretty close to complete combustion and just a little bit of incomplete burnt fuel is present... which really isnt a big deal; and even considered normal if you have the fuel turned up. bump the timing as others have said; and as long as you arent losing fluids anywhere i dont think you have much to worry about

 

the high heat is what led me to believe low timing

 

yea i still got stock HG and stock bolts so i heard that any higher than 16* is not a good idea especially since im running 50psi of boost...correct me if im wrong. with water/meth, i run about 1600* egt's.

i may try around 19* timing if u guys think it may help. of course the last time i changed the timing the timing pin broke (I think). so how else would one find TDC without it....

 

well i know white is def not raw fuel..black is raw fuel..black and white equal gray..raw fuel w/water. i just dont get how the timing will affect the color of the smoke..ex: timing is advanced burns the fuel more efficiently, less black smoke..timing is retarded, more black smoke..i dont see how it phisically changes color..ex: black white grey..

 

im confused too. im not sure what this could be. i am not losing coolant or oil. surprisingly i am not losing any oil which is odd but i am currently running dino oil cuz i blew an oil cooler and wanted to run cheap oil in case i got some water in the oil. but i use to use oil about a quart per 2k miles. would a clogged breather do this? i will look if anything is coming out when i get to work tomorrow morning and let ya's know.

i know retarded timing will cause a loss of hp. with the setup stated above the truck made 407hp on motor. timing was right around 6* according to my calculations from my blue point timing kit. it runs alot stronger now at 17*.

Thanks so far guys.
