So I was driving my truck home from work, started kinda hard. Long start and a bit hazy but was cold today. Went home grabbed a buddy. Then back to work to pick my other truck. I gave it a good rip down the highway but nothing got hot or anything. So I start the other truck while I let the diesel idle. When I get back I noticed its hazing heavily white smoke. Which it doesn't do. So I drive home and it's just pouring white smoking and really heavy black/ white mix when I leave in first. Also runs choppy/missing. Smells like raw fuel bad. Soo I'm almost sure an injector let go. They are nearly brand new diesel auto power 5x16 sac's. Seemed to run good since I got them. Although seemed to run a little choppy under load but I kind of wrote that off to sac vs vco and the 295 pop vs the 280 my 5x12 vco's had. But now I'm thinking it was a defect in one. Just looking for opinions. Also apon restart it blows black and white pretty heavily so I'm very sure an injector let go. Cracked maybe

 

Have you cracked lines to soo if the smoke clears while a particular one is cracked.
I would start by pulling them and doing a compression check.

 

I crack the lines to get an idea of which may be the issue but wasn't super definitive. Going to be trying again tomorrow. Why a compression check if Cracking one reduces smoke ?

 

Could also be a failing or failed fuel injector......

 

That's kind of what I'm hoping. But they are brand new, so not to pleased with that. I'm sure dap will make it right if that's the case but kind of an inconvenience for injectors with less then 2000 km on them.

 

First thing you should do is check pump timing it very well could have slipped.

 

Thanks for the help guys, figured out it was bleach in my fuel. Some hater put it in there obviously. Sorry for name dropping dap, injectors were def not the issue. I drained all from the lift pump water separator. Fuel filter was right full, local insurance is likely gonna take care of it. Question if anyone has an idea of how much damage this could do.'only ran for 5 miles if that. Drained injector lines and kinda sucked out the injectors and the ip at the dv. Anything else I should do?

 

Damn!! Now that's F'd up! Somebody obviously doesnt have the GONADS to face you for whatever reason. Time to get a locking fuel cap. Hope it all works out for you.
