    Head Gaskets

    Last time the Mahle wave stoppers were the preferred HG, when I did my LMM. Now I'm ordering for my LB7 with Fleece cupless heads... Mahle again or GM "C"'s? Thanks :)

    Passing "Smog"

    New Jermany is upping their agenda. I just found out that all diesel trucks will now be inspected annually. Before I throw in my compound 475 kit, I figured I'd reach out to those that may have info on passing in CA for smog. I figure NJ will be there soon enough! For now it will be a visual...

    Valley Charger

    I'm taking a 5min break at work to daydream :) My LB7 has 210k on the clock. Never tuned until I bought it at 200k. I have a compound kit going in once I get the time, and the plan is to stay SBE unless/until something goes boom. Kit is stock/s475. 12mm and 65 overs are waiting to go in...

    LB7 Heads

    I tried to set this up as a poll, but it's too open ended and too many choices, lol. I also tend to snowball projects like a MOFO, so help me reel it in maybe, hehe. I have 200k on the '02. HG's are believed to be original and I have no issues. I will be tearing her down to pull the...

    2002 FE9

    I was going to hold off until I started installing the fun stuff, but what the hell! lol. After deciding I’d had it with the NJ constabulary and their stupid target fixation with d_let_d trucks, I sold my beloved LMM. Some days I think it was for the best and most days I regret it. I bought...

    LB7 Exhaust

    Geez, it's getting tough to find an exhaust for these trucks now! Cat-Back like crazy... except mine never came with a cat, lol. It sure as hell isn't getting one either! XDP is nearby and anything without CARB (yet I'm in NJ) isn't up for sale; that includes things like larger cp3 etc...

    Converter differences X & G

    My truck is going under the knife this week and I chose a local builder with a great rep; I'm stoked! I've asked a couple people here about converter advice, and I have opinions that I really appreciate and value! Since Friday is my day to decide, I'd just like to gather as much info on the...

    lb7 throttle sensitivity

    I've been a busy beaver with this new truck. Tons of time and parts. This week was hydroboost, front wheel bearings, silicone motor mounts, and Fox front shocks. Parts are coming in like Christmas. LOL. At some point I have to get into the electrical code problems - tons of "U" codes... but...

    2002 a/c et al

    I did some forum searching and the last that I saw was Ferman recommending this kit for my ‘02. My compressor is leaking oil badly. https://www.rockauto.com/en/parts/gpd,9611824,a/c+compressor+&+component+kit,17507 Is this still the recommended longest lasting repair part? In a pinch I had...

    More of a re-Intro

    After getting nowhere trying to land the unicorn I want, I snatched up a very nice 2002 LB7 a few days ago. I flat refuse to entertain a new diesel and God help me, I almost bought a gasser 😳. Fortunately I have this stock lb7 now instead. For all her (many) faults, she is a an absolute...

    Lb7 VATS

    I haven’t found the elusive cream puff 1-owner black/black lb7, but I couldn’t stand being without a dmax any longer! I just bought an 02 :). It’s been a new problem each day this week, lol. Last night while driving, the Security light came on. Other than the light, there weren’t any changes...

    Getting back on the horse again

    My stupid busy season is finally over and normal work resumes. So I am going blind looking for a truck to replace my LMM. As much as it hurt to let it go, I've since encountered more people getting fined by NJ and it solidified my decision to cut bait and start over. That said, there's 1...

    Leaking nozzles, fix?

    I jumped in to help a buddy that finished his build and can't get the truck to run. I found several issues and everything is resolved except for injector problems. I had him bring them for testing and 5 came back bad. After talking to him about them, I disassembled and found that he...

    Duck the MANN or throw in the towel?

    After careful deliberation and discussion with a higher power (James, lol), this thread will be monitored by himself and his moderators to be sure that it does not become a bitch-session bashing of EPA/DEP/etc and/or politics and political bashing. Please participate with that in mind, and...

    FU James

    Follow Up James - those rear shocks that you revalved/rebuilt are even better than I thought! I was driving in another Duramax and it struck me just how terrible the rear ride has become on mine. Lo and behold, my caltracs were completely seized on one side and one joint in bad shape on the...

    Holosun HS507C-X2

    Looking to treat my aging eye to an EDC red dot and this checks all of the boxes - though a little chunky. I have a FF3 and an old c-more, and red dots are great. None of my existing ones have a shake awake though, so I’m looking for something different. Any opinions from the collective?? Tnx...

    Head unit

    Time to upgrade again - it’s been 10 years. Lol. I want Apple Car Play :) My setup is pretty modest - focal up front and a homemade 12” sub. I love my Sony’s control over the crossovers, filters, and sub level, so I don’t want to lose that. I could lose cd/dvd I suppose - I still have cd’s in...

    2019 traverse - anyone here a GM tech?

    I’m trying to upgrade my wife’s car to add a heated steering wheel. I installed a new wheel and everything is good so far. Now I’m onto the electronics. Her clock spring connector is the same shape as what the new wheel wants, but there aren’t the two pins on the clock side that the new wheel...

    Lift pump draw straw length

    Soon I’ll be raping a short bed 08 LMM of its AD165 and putting it into a long bed 07 lbz. Knowing the tank sizes are different, might anyone know if the draw straw length will still work, or are the tanks different depths? Thanks! Wally

    Bad ECM?

    I’m trying to help my buddy with a new-to-him LBZ. All good until suddenly both P0090 and P0045 and limp mode. Truck commands and goes full rail pressure on startup. I checked wires from FPR back to ecm and no breaks or knicks. Key on I’m seeing 2.63vdc at FPR. I backprobed at the ECM and found...
