LOTS of smoke and a slight knock

[dereku]

Ok so my truck has been running fine since the last time it broke down 2 weeks ago.

I was driving to work and one I pulled off the highway it seemed a little smokey. I realized I left my glow plugs on, I have a manual switch, I dont think this can be an issue my glow plugs were stuck on for the last 10,000 miles thats why I have a switch. I flipped em off and no change.

By the time I got to the shop it was puking out so much grey black smoke I immediately shut it off. It smells almost like a 2 stroke mixed with diesel it is hard to explain.

I restarted it and there was a slight pinging and then it went away and all the smoke started.

My turbo is newer and the oil level is still dead on full. Could it be an injector issue?

Mine did this when my oil o-ring on the injector was bad.Smoked bad til it got hot and then it stunk terrible.Not too long after it started using oil bad.Hope this isn't your issue.

Mine stay smokey and stinky even after it warmed up. I am thinking the extreme cold maybe caused it to shrink up and crack.

I didnt let my truck warm up as long as I should, only 3 or 4 minutes, I was in a rush so maybe it caused an issue.

any one else with ideas? I am thinking well hoping it is just injector o rings. I am pulling them next week.

I ended up pulling them out and had 1 bad oil o-ring 2 bad fuel o-rings and 1 bad injector.Did the valve covers glow plugs harnesses and all while in there.Good luck man.

hello i have the same problem without the smoke mine clatters loud it sounds realy bad right before it shifts gears

[thew1ld]

Im wondering if low fuel pressure would cause this or maybe a sensor

[dereku]

There could be a ton of problems to cause clattering. Its the smoking that is my issue.

I am going to pull the injectors out on Monday so I will find out if they are bad.

If the orings are bad is it noticeable? I just hope it is not a bad nozzle.
