3.0 Duramax

[1FastBrick]

Wouldn't it be wonderful if these kids who are engineers these days were to design an engine if mechanics were allowed to inspect and sign off on the new design before it could go into production! Needless to say that will NEVER happen. I know back in the day Bill Lear (who designed the Learjet) would go on the maintenance floor and look at the mechanics working on his jets. If he saw the mechanics having issues with the engineering prints that had to work with he would go upstairs and get the engineer who did the work on that drawing. He would drag them down to the main floor and make the engineer show the mechanics how it was supposed to work. Needless to say, 99% of the time the engineer went back to the drawing board to redo drawing he had put out! I'm afraid those days are LONG past us!

I really had high hopes for the 3.0 Duramax, I do think there is a good market out there for an engine like that even with all the EPA mandates coming down. It is just sad that stuff like this shows up on a clean sheet design. I just pray my LMM has a good long life ahead of it. I just freshened it up last summer with a two tone Katzkin leather interior and it looks great! The original SLE cloth had seen better days after all these years. Dean

Your LMM should be just fine with the exception of the Dash...

Yeah, got a couple small cracks but hard to notice. The truck stays garaged all the time. Even when I take it to work it goes into the hanger garage. Got it tuned with a lite boost in power with other mods to kick up the overall reliability. One of the first things I did was to add a lift pump and then at 50k I changed all the fluids to synthetic. I was amazed how much better the Allison tranny ran with the genuine Allison fluid. I will never go back to Dexron 6. Added the S&B 62 gallon fuel tank a few years ago also. The old LMM is a towing machine! Dean

I've believed this all my working life. Doing maintenance for most of that. I've always thought the guys designing something need to be the ones to do the maintenance and repairs during the testing and trials before the main release. Minimumly.

I have a similar issue here with the hotels Indo maintenance in. Every renovation the rooms get darker and darker and guests keep complaining but designers and architects keep specifying lamps and bulbs with less output. Furniture, cabinets, fixtures, etc are also getting cheaper and more difficult to keep in good shape. The owner, architect and construction manager need to spend at least one week in one before signing off on the whole building

I worked a Place were we built prototype and concept cars when I was younger. We wasted so much time and material building to an imaginary print because things were designed in space on a computer. but not everything was fit together or had material thickness added in. The fabrication team always got the blame for being over budget on both time and materials. By the time I left, When something didn't fit, we made the engineer or engineers come down and Physically look at the issue.

Nice!

Been my wife's theory since I've known her.. Typically learn of an issue when I hear it pull in driveway...

Mine too lol. Had to do her front brakes last weekend... Inner pad backing plate exited the caliper bracket (relocated itself to between the rotor and the dust shield and fell out when I removed the rotor) and the piston was way over extended, and the inner half of the rotor was about half the proper thickness... 'It just started making noise a week or two ago'... Between that and all of the rust residue on the wheel and side of the car, it was making noise for MONTHS
