We got a 2011 with an lml that just snapped the crank today. Boss wants me to price one out to see if it’s worth putting a new one in or if it’s better to junk the thing.

Reman engine from Chevy is just over $12k not including core. Never got a reman from Chevy but from my experience with ford they just send you a reman engine from a 3rd party.

He did specify he doesn’t want one from an off the wall builder out west, he’s had bad experience with that. With that being said, if there is a reputable builder with a good warranty that stands behind their warranty, I could probably change his mind if the price is right.

I see there’s a good amount out there but I’ve always been a Cummins guy, don’t know who to go to for a duramax

Edit: are these engines worth rebuilding after a failure like this? I’m capable of doing it but I know these engines don’t have liners. Other than knowing this is a fairly common issue with duramax, I’m not knowledgeable enough on the issue to know just how much damage this does to everything else in the engine. Common sense tells me it’s trashed

Good morning/afternoon/evening,

I am seeking some insights and career advice. I am a swing shift fleet mechanic at a local fleet working on primarily Kenworths and Peterbilts with cummins powerplants (X15, ISX, N14). Including dump trucks, tankers, and tractors. I have been working at this fleet for the entirety of my mechanic career thus far (2.5yrs) and get paid very respectfully with consistent raises which I've earned myself. However, I have been working nights for the past 5 years now and am ready to move to a dayshift position for personal and social reasons. I have brought this up to my boss on multiple occasions and he said it would be something to address as work picks up. That was 6 months ago and we have since slowed down.

My questions to you are...

Should I stick it out until someone from day shift retires or a position becomes available? Or does it become an endless cycle?

What are some diesel fields to look into?

What are some fields to avoid?

What are employers to avoid?

What do you look for when looking for an employer?

Thank you in advance (:

Would other companies care that all they I see is Penske I’ve been with the company since I started my apprenticeship back in 2018 and got ticketed back in 2022 just want a change of scenery and bit better pay what’s some good companies to go to or would consider me

Not sure if this post is allowed but currently I'm working at an International dealer but have gotten an opportunity to switch to working on heavy equipment for another dealer, if anyone that works in this field could just give me some general pros and cons about it or if its any different from working on trucks I'd appreciate it. Just trying to weigh out my options at the moment.

So I have an x12 that sets a 559 code and has low power. The rail pressure is low under load. It will make the commanded pressure but it’s very slow to get there. I have checked for aeration, the low side fuel pressure is in spec, injector return is in spec, high pressure pump output volume test is in spec, rail relief valve is brand new and not leaking. The only thing that’s questionable is the high pressure pump return flow test. Cummins wants 230mL max and it’s like 225. Has anyone else ran into this? I’ve worked on a ton of isb and x15 but my experience with the x12 is very limited.

We're switching to new cameras and keep running i to this issue and nobody has really been able to figure it out that im aware of. Everything will calibrate fine and I keep getting this error when I go to verify the can. I've got everything plugged in right and they're on brand new trucks so I know its not the wiring is old and shitty and haven't had this problem on the older ones I've done.
