2013 Stock with 465,876 with CP4 still going strong. Change your filters and use a fuel additive. Have done this day one and no issues. Will go to CP3 when the motor goes for a rebuild shortly.
Doing a CP3 conversion at 180,000 right now. Haven’t had any issues with the Cp4 but I’m not gonna wait around for them.
I have a 2012 LML Duramax with 322,000 miles. I did the CP3 conversion at about 175,000. Installed a FASS 165 lift pump. I deleted it and has a CAI, programmer(towing tune) and 5 inch turbo back exhaust. I also changed over to Catepillar oil filter, fuel filter and water separator. This thing runs like a champ, no issues. It's my daily driver.
Have a 2016 Duramax with 41,000 miles. Use it mostly to pull our 5th wheel. I procrastinated for several years about the CP3 conversion. I did put an Airdog lift pump on approx. 1 1/2 years ago and always run additive. I have followed all the bad reports about the CP4 and quite frankly it really concerned me. When my extended warranty expired I decided to bite the bullet and do the conversion. Being a retired aircraft mechanic I felt that even though I had never done this conversion before that I would give it a go. In July of 2023 I completed the job using and S&S CP3 kit. This was their latest version with a new block for the 9th injector and a port for the temp. sensor. Per kit instructions I did a regen on the DPF system and so far I have put around 1000 miles and pulled our 5th wheel with no issues. I did this for peace of mind as I dreaded the thought of a complete failure on the road especially pulling the trailer.
I have been doing research about the LML trucks so this helped a lot so thank you
Glad your building this truck, I’m looking forward to learning the entire platform
Just had a BD cp3 conversion installed on my 2016. The truck had 85,000 miles. The cp4 didn’t fail, just wanted to make sure the truck stays reliable.
I needed a new water pump. I have had my cp3 conversion sitting in my office for other 3 years. Since I needed to replace my water pump I decided to go ahead and do my conversion..... 330k miles, original stock cp4 pump, original stock injectors, installed my lift pump about 100k ago. Had zero metal shavings but did have pieces of rubber and plastic on the screen. Blows my mind it was still running without an obvious issue.
I'm at about 230k with mine and no issues (yet). While I know it does get blown out of proportion, it's just that thing that lingers in the back of your mind... when is it gonna fail? Did you use lubricity additive and/or live in a biodiesel state?
Lift pump is a must! I agree 👍 I installed a Air Dog 4G 165gph in my Lmm and have tried to advise my brother in law (lml owner) and another friend who has spent 10,000 on new injectors and 7,000 on new fuel rails on his Lmm and still won't consider a lift pump! Same thing with my brother in law! Tho he's on borrowed time with his CP4!? Great advice Brother! RDS Turbo nice upgrades! 🛠🔧☠️🤘🏻💨💨🏁
2014. 102,000 and I just did the CP3 Conversion. Among some other fun stuff...Finally. Runs much better now! I don't know why I waited so long. Mine was strictly preventative maintenance since I just hit 100,000 miles. Now a couple weeks prior, a relative of my wife had his CP4 on his 2016 self destruct. So, that was the final wake up call and my wife really started worrying so we pulled the trigger.
Awesome! glad to hear it's running great.
Does your buddy with the silver LML have a channel ? I want to see more of his truck
I just bought a lml and want a conversion but havnt gotten around to doing it. But it runs good still with 250000 miles
I just converted mine myself. 2015.5 with 234,000 miles. Took me about 8 total hours of labor, but shops book 12.. saved thousands, and it runs great. Added peace of mind! Used the Lincoln Diesel Specialties kit
How did your FPR look? any metal shavings?
@@JWMontoya I could barely make out 2 or 3 tiny specks on the screen. Good enough to mark my injectors “safe” lol. Thank God! I bought the truck completely stock at 230k just three months ago. Have been running EDT. The intake plenum had 1/4” of soot buildup from the EGR and PCV. I’m going to need to replace that intake with something soon!
I’m thinking of going with there kit.
@@davidblevins9513 do it!
I converted my 2015 at 125K before it failed
This is off to pick of that video but would you say it’s worth replacing the Down pipe of a deleted 2019 L5p?
I did do a cp3 co conversion on my 2013 lml. Should i still get a lift pump?
Which cp3 pump did you go with? I was looking at S&S. They have different models. If you’re deleting I’m assuming there’s no need to pay extra for the pre tuned pump, your tuner should take care of that right?
Just bought a 2016 with 145000 miles. I don't know what previous owners did but i run edt every tank and no lift pump yet no delete or tune yet
I have a 2004.5 lly just did new head gaskets now im not getting the high pressure. I put a air dog lift pump. So.e reason im not getting fuel pressure any advice ? Truck was apart for few months.
does the CP4 fuel pressure regulator go back on a CP3 conversion or does ie use a different regulator ?
I have a 2012 lml currently at 215,000 miles... Should I do the CP3 conversion????
I have a 2016 LML with 110,000 miles. When should I start to worry about CP4 failure?
LML with 183k with a fass (install at 30k)
Original cp4
Runs like a champ
Mine 2016 with no egr or def setup and i still have cp4 with fass added and got over 225k miles but never able get cp3 conversion yet cause of cost and bills from credit cards had replace steering with HD cognito setup cause of ball joints were going out and i got turbo boost code p2263 nearly every day unless its cold out and a rarely p128e code pops in a blue moon with p2263 code fer under boost and cant figure out whats issue fer bout year and only thing not did was change turbo cause hate when it goes in limp mode uphill but i would like get rds 64 9blade setup
Gives me hope 😂
My 16 has 145000 on it. I’ve had a fass on it since I bought it in 2019 with 55,000 on it. I’ve always ran an additive whether it be hotshots or diesel power service.
great way to take care of the CP4 pump
Im definitely terrified to try ry a cp3 conversion by myself. Its the only ride i have so I can't screw it up 😂
It was nerve-wracking for sure! Truck was down for a total of 2 days. Completed with all common hand tools. Just make sure you have 19mm, 22mm, and a 24mm wrenches and some type of small universal/wobble extension for the 10mm y-bridge nuts. I used a large adjustable for the 24mm. Lincoln Diesel Specialties pump+ gasket kit. New Y-bridge gaskets definitely needed for proper sealing.
2011 lml 150,000 cp4. I'm interested in doing a lift pump though just to. Just out of curiosity if you're familiar with it does installing a lift pump set off a check engine light and do you have to unplug the electrical if there is some on the CP4
It does not throw a code what so ever. I’ve done a video on lift pump installs.
This is the lift pump we sell a lot of: jwmotorsportsco.com/collections/airdog-lift-pump/products/airdog-ii-4g-df-165-a6sabc409-duramax-lift-pump
Which kit are u using?Which one do u recommend?
I used Exergy Sportsman with HSP conversion kit
i think my cp3 failed. ficm good 2004.5 lly had banks ecotune, banks ram air intake. crank no start. fuse check pass, no codes but still showing check engine light. any thoughts sirs or ma'ams?
How do you know your FICM is good? Read the codes on the truck first
Iam still driving 6.6 Duramax with the CP4 and it’s still running great with 260.000 kilometres it’s never let me down yet, 😅where’s the wood
I have a 16. 130,000 miles hadn’t did anything to it. Cause hadn’t found anyone locally to take a look at the thing.
If you have the space and tools to work on it yourself. You're more than welcome to
2013 285k tows everyday all day weight loss no lift pump living on edge!
One of my friends has a lml with 700,000 on an no problem with cp4 .
So the 17 duramax doesn’t have a cp4 pump wat exactly does it have?
lp5 have the hp4
I did one on my 2015 at 90k miles
How did your FPR look?
Yooooooo
