Honestly I was surprised when I saw that too haha. The parents seem to think it's water in the fuel

ok based on your pics and this, then you probs need a new turbo. worn bearings will allow oil to seep into the intake and burn in the engine, making the smoke smell of diesel. check to see if there's any play in the turbo shaft and if there is, junk it in favour of a new one.
>water in the fuel
draining the fuel system should have been the first thing they did, surprised it's not been done.
Do both of these things before anything else
Leo Torres
actually you'd be better off unbolting the turbo and running your finger around the inside of both the cold-air side and hot-exhaust side housing. if there's some oil in both and play in the shaft, your turbo is dead.
if your turbo is fine, you could have shot piston rings. increased gas blowby raises crankcase pressures, forcing oil through the breather system, through your PCV valve and into the intake, where it is burned by the engine.
Hunter Ross
Alright, so drain the fuel and if the problem consists, then it's oil making the smoke.
Could the water in the fuel (if it exists) cause the injectors to fail?
Also I've just been told, they took it to a shop not long after it happened to try a compression test, and I guess the shop said they couldn't test it without new injectors (after charging $300)

>if the problem consists, then it's oil making the smoke
burning oil gives you blue smoke that smells of diesel. white smoke is water in the engine. it sounds like you have both problems desu, so if you drain the fuel system you'll probably still have a problem to sort.
>Could the water in the fuel (if it exists) cause the injectors to fail?
honestly not sure. do a leak-back test to see if the injectors are in decent condition.
>I guess the shop said they couldn't test it without new injectors
sounds like bs, but perhaps your brother cracked an injector when he flooded the engine. if it has new injectors then i wouldn't bother testing them.
to drain the tank, siphon off as much diesel as possible with a hand pump, then idle until it dies
Michael Torres
It's got the same old injectors, and how would water work its way into the fuel anyhow?
Recently rookie at this stuff, how does one do a leak-back test?
Nathaniel Flores
Breaking news, apparently my dad thinks the turbo doesn't work anyhow, and that he thinks he recalls the berrings being out and it not spinning. That said. This turbo is aftermarket. Wouldn't it run without the turbo?
Wyatt Martinez
Well, we don't have the old parts to entirely remove the turbo, but would a bad turbo result in the smile at least, not even worried about it running poorly
Nathaniel Perez
damn thats shitty. yeah it would run but badly, especially above 1.5k revs.
google it, you simply connect tubing to the leak-off nipples on the injectors and run the engine for 30 seconds, collecting the diesel that leaks back into bottles. if a bottle fills up really quickly, that injector is dead. water can get into the fuel system if your brother drove deeper than the fuel filler cap

Found this gunk on the radiator cap, any relation?
