Wanna know your thoughts.

I have a 1987 F-250 6.9. Recently I removed the engine from the truck to install all new gaskets, freeze out plugs, ARP head studs, 7.3l IDI Factory Turbo Injectors and a 7.3l Factory Turbo IP. All this to put a Banks Sidewinder Turbo on in the Spring. Turned it over for the first time about 3 Days ago and it is smoking black smoke, just a haze really, at idle. Is this bad? I don't even have a load on the truck and it is not hot. Understanding EGTs are a huge factor in life and performace of a Diesel. This is my first diesel and after all the work I really don't want to ruin anything. I plan on hooking up a pyro. Just didn't get it yet, still finishing assembly. I didn't know if anyone has done this or not. Please advise! What should the max egt's run? Will getting to much fuel pressure make fuel go in the oil? Will I be able to drive with out the turbo kit on? Should I install Turbo and wait to drive? Anything will help. Thanks.

Even if the pump is maxed out, you shouldnt be smoking black at idle.

I would suspect a timing issue.

Its not solid black just a haze really. I would think if the timing was off it would not run. If timing is off can this be a problem? I know alot of guys with Cummins and the Advance Timing all the time in the 12v. I am pretty sure the Timing is OK. Took off Front Timing cover and lined up "o" marks on the cam and crank gear. Then lined up "y" marks on the cam gear and the injection pump gear. If that is wrong pleas let me know.

Nothing wrong with a little advanced timing, not alot though as with more timing comes increased cylinder pressure. Advanced timing could cause some black haze at idle. Retarded timing will usually give you a bluish looking color smoke, like if your motor were burning some oil and it will usually run like crap. I'm basing my knowledge off of a Cummins though, but the principle should still be the same though. Somebody correct me if I'm off on this though.
