    Bad parts counter experiences

    I always take the time to look up part numbers before I go to a parts store. I found the time it takes for me to look up the numbers pays off in time saved at the parts house. As you pointed out, 25 seconds on the internet avoids the painful 20 questions routine at the store. Although, it...

    Bad parts counter experiences

    +1 I'd love to hear some stupid customer stories.

    Bad parts counter experiences

    The problem I'm seeing is that parts houses are just another job for people. They just ask the questions the computer tells them to ask, and if it's not in the computer system, it must not exist. Went to an O'Reilly for an axle seal for a duramax that was leaking really bad (would have gone...

    What I'm reading is "when I hit the 4>5 shift (60-70 mph), the trans limps and the truck slows down"

    RIP Cruze Diesel?

    Purely speculation, but it may be the "Medium Diesel". Matches the bill - all aluminum, 1.6L, etc.

    RIP Cruze Diesel?

    Looks like they are going with a 1.6L diesel allowing for B20. I'll try to dig up more information on it, but this press release mentions it for 2017.

    RIP Cruze Diesel?

    Is it going to be a GM design or another VM Motori? Sounds promising.

    RIP Cruze Diesel?

    I was browsing GM's engine selection for 2016 and noticed a lack of 2.0L diesel. I checked on Chevrolet's website and noticed that there is no longer a Diesel trim level or diesel engine mentioned. Anybody have information on this? Any speculation as to why (emissions or cost-prohibitive...

    Transfer case

    1) GM recommends (and I run) Dexron III Oil (GM P/N 12346143) or equivalent Dex 3 from your preferred name brand 2) 2.0 quarts Torque the drain plug and fill plug to 15 ft-lbs. If you strip the head of either of the plugs, replace them with aluminum plugs (like they are from the factory) to...

    New duramax rods iv been working on

    Being a numbers guy, (and given my background in this field) I'm happy to see some documentation appearing. This is a different format than I'm used to seeing in the US steel industry, but most of the information is there. I'm assuming the hardness is Brinell, judging from the range. As others...

    No fuel to filter head after rebuild

    This sounds like your fuel pressure regulator is getting sticky. They do this after a while on the LB7s. It actually causes a noticeable fluctuation in idle. If you have a way to watch your commanded versus actual fuel pressure you will notice it doing a sine wave from too little to too much as...

    Things You Find When Digging Through The Garage

    I actually had a previous owner mail me parts they found in their garage over a year after selling the vehicle to me. Hey, free parts.

    LB7: Upper Oil Pan Oil leak?

    If it is leaking above your oil filter (and especially from the back), it probably isn't the oil pan. I've seen a leaking turbo oil drain drip down the back of the valley, which then typically can run down the driver's side of the block (there's a valley drain hole back there - see the attached...

    Allison 5sp: Build 2.0

    This right here has me worried. My truck isn't liking the 3-4 shift every couple of times it goes through that range. Other times it flares the shifts. I had assumed it was something a built transmission does because it's been doing it since I started making some power ~1000 miles after the...

    Service 4wd issues

    My V2 has read all the 4x4 codes I've run across, so there may be a U1000 (Class 2 data bus issue) code indicating a communication problem between modules and the front axle, transfer case, etc. Check to see if you have any U1000-series codes as well as check for U1300, U1301, or U1302 codes...

    New Diesel Fanatic Need's Help

    Depending on the power you're putting out, that may be why the transmission is shifting terribly. They aren't intended to behave well under power levels higher than stock. After a built transmission (depending on the level of the build) you can put down stupid amounts of power. Even a mildly...

    Non mechanical savvy, desperate for advice

    Do you mind sharing the dealer? The cheapest I've ever been quoted was $8,500 (+tax) for a LB7.

    New to Efi Live

    There are several methods of getting an EFI Live tune on your truck. Unlike other "tuners" (Edge, Hypertech, etc.), EFI Live is a software program that allows the tuner (taking about a person/profession this time) to alter the tables and parameters that define how your engine runs. This becomes...
