I recently purchased an 89 aftermarket turbo truck to replace our 6.9 bullnose; placed in it my good starter from the 6.9 (it would fire immediately), 1000cca batteries, 2/0 cold weld crimp'd cables, R&D 90cc pump and stage 1 injectors.
It cranks hard and fast, but requires 20+ seconds to fire and billows white smoke.
Per, "icanfixall" in below thread, I'm today going to pull the timing gear and verify timing by moving to tdc and setting the timing gear. I suspect the issue could be due to a previous owner placing the timing 180* out.

My R&D pump and injectors have around 10k miles on them, I'm doubting they are causing any issue.
The truck also has a lot of oil pooling inside the turbo (ATS kit) air filter flange, possibly blowby?
the immediate previous owner attempted to get it back on the road by resealing the cooling system and replacing the water pump, it could have had an old cooler in there that didn't hold pressure and popped the headgasket, maybe worse. When I purchased the truck it had the original IP and injectors, all wretchedly out of spec.
I suspect the truck has been driven into the dirt and there could be massive amounts of carbon built up in the piston walls preventing the rings from making a good seal, I also want to seafoam the fuel filter and run it for a couple minutes, then let it sit overnight and see what happens.
Am I on the right track here, guys? Anything else I should immediately do? I won't have access to a proper compression tester until at least the weekend to verify if the head gasket/otherwise is good.
Cheers and tia,
Robert
