    Thank you Chago for your personal service on my motor! Your expertise is phenomenal and I…read moreappreciate you explaining details to me.

    Been working with these guys since the end of August 2019. He is how we met…read more We started home back to LA, after spending the 4th of July in Alabama. On the way home, we threw a rod. We limped the truck back to our property in Alabama and picked up a rental. Once back in LA, my dad and me looked all over for a replacement engine. 6.6L Duramax for a Chevy 2500. We talked with at 15 folks about getting an engine. Some were pulled out of their trucks after being in accident's or other strange things. A few of the remanufactured shops we contacted, had prices through the roof. Some of the prices for a used engine were down right scary. I told my dad, why pay for a used engine, that we have no idea of the history on. So we looked more at getting a remanufactured engine. A lot of the places had scary prices, that would make you not want to deal with them. Just by luck, I found MTZ on Craigslist. My dad liked the price, so we ordered a remanufactured engine and asked for it to be sent to Alabama. The engine arrived on time. We brought one of our friends from LA to help with the install, but he ran out of time before he is could finish. Dad and me tried to figure out how to finish hooking up the motor, but at some point it was above my echelon of repair skills. We decided to send it to the local dealership, figured they would be able to get it completed. The guy from the dealership got the truck hooked back up and started, but ran into some coolant leaking issues. He believed that it was a blown head gasket and could fix it, if I gave him my first born, left kidney and right testicle. Toooo much money for the job, so I took it to another shop to have them run a diagnosis and trouble shoot the issue. The new mechanic said the same thing, blown head gasket. It's been months and now to hear this is heartbreaking. Dad calls MTZ upset and ready to do legal work against them, they say bring us the motor. The motor had zero road miles on it, just start and running for a few minutes in the different shops. After the motor is pulled and loaded up, I head back to Houston to have it checked to see what happened and if it was damaged, or pick up a replacement. As soon as I get to the shop, they off load the motor and in front of me, remove both heads. Well come to find out, the head gaskets were still good. Come to find out, on the back of the motor, the back plates did not make a complete seal. Since it did not seal, water was leaking it the exhaust and the oil(wish I would have known that, before driving all the way back down to Houston). I gotta say, these guys went out of their way to work on a problem, they did not create. Speaking with the owner, he expressed how in this business. They can make mistakes and will honor anything they did wrong and try to fix it. But in my case, even though they didn't have to be cool about a problem they didn't create, they were down to troubleshoot and ensure, the product I'd be taking back to Alabama was good to go. I will be heading back to Alabama in the next few minutes, with a motor that was disassembled cleaned and reassembled with another new head gasket installed. I'm giving five Stars for the customer service part right now. But my truck should be running in the next week, and I will do an update. But from the warm and fuzzy feeling I'm getting from watching these guys work, I believe it will be just as good next week.
