Air cleaner is unhooked, the turbo turns free. There is no shut down flap. Checked exhaust pipes and muffler for blockage. Could you tell me what the setting would be if I went back to the 9G85 injector? Thanks for the input.
I'm betting after those injectors were bottomed out they dribbled pretty badly. I had 1 dribbler in a 3406 cat that smoked the whole yard up at idle.My 92 manual shows using the 1.600 timing tool with the 9290 injector .
As for the black smoke check the emergency shutdown flap at the blower intake , clogged air filter , collapsed air intake duct ,& turbo failure ( with the engine off make sure the turbo spins free by hand ). Black smoke is a sign you aint gettin enough air .

I have seen the key sheared on the crank gear.
My manual don't show the 8 V 92 TA using the 9 G 85 injector . However the 9290 seems to be the common injector in that series .
Let me take some time this evening & scan in the tune up spec charts that show all the combinations as I don't want to miss speak & steer ya wrong .
My manual is a 1981 vintage .
As far as plunger travel it may be the plunger travel on the OP's injectors Bottoms at a higher point than a standard Injector. The cams may be the standard lift.Is the crank gear keyed on a 92? Seem to recall all the 53-71 series engines had the gear that drives the cams at the rear of the crank were held on with I believe 6 3/8 fin bolts with one offset to be sure it is installed correctly. Plus I don't see how even if the cam was out of time with the crank it would effect the travel on an injector.
Don't know what the problem is but sounds like there is either a mistake in the way the injector is being adjusted, there is an error of some kind in the injectors themselves or the cam has too much lift on the injector lobe.
Not sure if there is a spec. in the manual on the lift of the cam lobes for the valves or the injector. I don't see any such spec's listed in my old V71 book.
Ok , opened up my newer 92 manual ( 1988) and sure enough around the mid 1980's we start to see the 9G series injectors .
Top scan is the blown up off the same page so we can see it better . Yellow lines are injector , horse power , & timing .
TD25, Thanks for the help and taking the time to look these numbers up. I am glad you found the 9290's were speced out to the 1.600 range. However the 9G series injectors show 1.456. And unless the 9G injector has more travel I will never be able to set it to that specs.
