Backfiring?
Smokestack did something like this the other day. Smokestack is a spring chicken (69K miles on the odo) and well-cared for. It sounded like backfiring as in a gasser but had no feel to it.
Never in the history of my diesel world has this happened to any truck I know.
What was that?
What causes it?
Should I care?
Smokestack got a new tank of fuel and a Diesel Treat chaser a day or so later. Nothing since.

Yes, I was in traffic.
But no, I don't think anyone else was close enough to have this *not* be Smokestack. But I got all paranoid, so I can't be sure.
No, I'm not important enough to be a shot at.

A meth lab in Oregon. I thought this was a 420 state, not a tweaker state.

Did you hear it or feel it? Intake or exhaust back fire? Does smokestack have stacks, and if so, has it been raining?

I had S60 Detroit back fire once when trying to start it cold and gelled. Blew both ends off a new muffler. The thinking was unburnt fuel in the exhaust got ignited by slowly burning fuel pushed out an exhaust valve.

No, I didn't feel it. That was the weird part, along with the fact that no diesel in the history of my world has ever "backfired." Given your stories, I think some flames and explosions would accompany those if it happened in a diesel.
I have concluded than I'm an idiot. But perhaps an idiot important enough to be shot at.... and that I can get meth in sleepy little Oregon.
A very educational thread. Thanks!

They can backfire. My 96 did 3 times. The pins going into the valve cover plug didn't lock in place with a new plug. They would randomly make contact which would cause the injector to fire out of time.
Believe me I thought was too when I heard it.
