2011-2016 LML Duramax Buyers Guide

[@Justin-tq9pv]

I had a 2011 LML that started with 280,000 km on it. Used it for a hotshot running Indiana to western Canada. Deleted it the day I got it, cp4 killed my wallet at 315,000km, head gaskets popped around the 330-340,000km mark, turbo blew from a fluke accident where my oil filter literally broke off while driving in Sask when it was -40 out. Trans & crank held together the entire time I owned it though. Sold it with 681,000 km on it. All in all I’d say it was a good truck

I just saw a LML I was interested in, started researching and came across your video. Thanks so much 🙏

[@higherlifts420]

My 2015 and 2016 were the best trucks I ever had. Just delete it and you'll barely have any issues

[@mscar8024]

Ironic isn't it? Govt vehicles get the DEF delete straight from the factory, but you? Sucks to be you.

What about maintaining? changing oil w filter every 10k miles. What else and how frequently

[@Iwant0ut]

Super helpful video! Just curious on if the broken cranks are from the trucks being tuned way past stock power or if stock lmls are breaking cranks aswell?

[@dirtydieselcustom]

We have seen it more on tuned trucks for sure, incorrect timing on the fuel injectors can over-stress the crank. We sometimes see it on stock trucks too but it is less common than tuned trucks. Cheers

Trying to find a new truck I don’t even want one anymore

[@jamesgrose4819]

300,000 miles on a 2016. Ehhhh,

[@kalebsherwood3484]

You should do an lmm guide

[@shitaki13]

Are you going to do a LMM buyers guide?

[@dirtydieselcustom]

We should have one soon, I'm doing research at the moment. Cheers

They are great trucks... Just be ready for a $10,000 repair...Thanks for talking me out of a LML.

CP.3 conversion eliminates all the worries of that. Also, if you’re lucky and live in an area where you can delete emissions without any fines then it’s basically a solid motor. Only things left to maintain would be your DEF system. But unless you live in a place with freezing temps you have little to worry about. I live in hawaii, bought an LML Chevy from a friend and converted to CP.3 ASAP. It’s been a reliable since then, plan to do the emission delete soon since Hawaii doesn’t have emission BS. Even without the delete tho i haven’t had any problems with the DEF system yet. The warm climate here probably helps

[@Christafa-ss3lu]

@@_N4VE_ I passed on the 2015 and bought a 2019. Replacing the CP4 to a CP3 is over my head. I'm no diesel mechanic so I'm hoping the L5P holds up.

[@_N4VE_]

@@Christafa-ss3lu I hear a lot of good things about the L5P so you should be alright. A lot of my friends have a one and love it and tell me that deleting emissions on those motors makes it even more efficient! If you live in an area without strict emissions laws i’d highly recommend finding a shop willing to delete!

[@Christafa-ss3lu]

@@_N4VE_ I hope it works out. Ive been told it can be done. But the expense is concerning.

[@_N4VE_]

@@Christafa-ss3lu yah deletes will cost you a good chunk, basically paying for the labor and installing the new exhaust pipes and a retune. Based on the shop prices vary. Well worth it for longevity and reliability tho! MPG even goes up based on your tune
