Oh I am beyond pissed. I just hope it gets fixed for good. And I know that deleting it will fix the diesel leak because I read that there is a seal that lets diesel into the exhaust during a regen to help burn off the soot and that it's an easy fix. But the coolant issue is my biggest worry. It's not leaving a puddle on the ground. I really hope it's not a head gasket.

You have a 9th injector that is bad, thats what i bet it is. I replaced mine at only 9,500 miles. But I got it replaced under warranty then did a full delete promptly after

I've heard that's what it is, but I just don't understand why inject diesel fuel into the exhaust?

thats fucked up. if deleting fixes the problem maybe you can get them to pay for the deletes.

if head-gasket is gone dont even buy it IMO if you do get them to install ARP headstuds free of charge.

If it is head gasket, which I doubt it is, I wouldn't even have it done unless ARP head studs were being put in.

its for the regen cycle, it will inject fuel to burn off build-up in the dpf and clean it out

^This. And I believe to remove that 9th injector is alongside of doing a CP3 pump conversion.

I've heard some horror stories on the H&S tuners on Duramaxes. Local diesel shop has replaced a broken crank twice on an LML that had an H&S tuner on it.
 
I'm running a hot tune and cp4 is doing just fine. Have never drained the rails and I just took it up to 140 on sunday......

If you have the money, might as well, but it seems to be a few isolated incidents with the cp4

140 is a guess tbh, I messed around with a cts-v wagon when I left HB, Anthony was with me, but it took a good 5 seconds to come down from being pegged

Well I've got an appointment Monday morning at the dealer. To hopefully get everything fixed.

My headlights are ever so lightly hazed. What's the best way to fix this before I clear them?

So I've got the exhaust installed. Mini Maxx installed. Removed steps, def tank, and installed 6" tip.

Still haven't fully removed the EGR. Gonna do that hopefully next weekend.

Also cranked up my torsion bars all the way up but only gained about 3/4".

And here's everything that's came off so far.
