Flames out exhaust

I was driving my truck coming home, boost was less than normal and the turbo was making a lot of noise through the air intake, it sounded obstructed (was making a loud noise, possible clogged air-filter).
Power became poor, steadily decreased, lost boost, fire from underneath the truck coming out of the down-pipe (no exhaust on truck). Black soot and flames all over the side of the truck. Finally popped and self-extinguished. At least one of the cylinders is hydrolocked, cranks over half a revolution and then the starter won't crank it anymore.

Bad injector?
Turbo screwed up?

What am I looking at money wise and labor wise?

Guess labor wise, you'll be pulling off the intake and turbo, checking it. Might as well pull the heads, no point in not. Yea, you could pull GPs and injectors but if it esploded then just do it. Pull cab just to make it easy, you're gonna be in there good. So . . . a lot.

Be careful during disassembly and document your findings. If you pull injectors you are going to dump fuel into the cylinders. Maybe pull plugs first to find the wet cylinder(s) and go from there. I hope you find something silly and inexpensive........or as inexpensive as a 6.0 can be.

No way I am pulling the heads. If it comes to that I will find someone to pull the cab and let me work on the engine.

I'll pull the glow plugs and find the flooded cylinder and replace that injector, check the air filter and turbo out.

This truck has been a pain in the ***.
Deleting the EGR was a huge task despite what people say.

The truck has been sitting for a while, I tried starting it and it started up and idled fine. Engine oil is LOW.

I think the turbo seal popped and caused the engine to suck oil.
Checked codes.
No injector codes.. only EGR codes (EGR is DELETED) so those are expected.

Yep.. that's what it is.. there's oil leaking out of the downpipe, a considerable amount. TURBO SEALS... big relief.

A leaking turbo seal wouldn't cause the engine to hydro lock though. Are you sure it's oil in the exhaust and not fuel mixed with soot? When it started did it smoke like crazy and have a knocking noise to it?
