I had met jorge when he worked at another machine shop in fontana, he was always very helpfull and a very knowledgable person, i found out this was his shop and i called him one day because i needed the injector tubes changed on one of my engines(water in diesel). so as i was speaking to him he asks me to explain my problem and he tells me that he can do it but i would be wasting my money..obviously i disnt want to hear this i just needed the job done..so i kind of acted rude towards him and he always managed to keep his cool..long story short i call another shop to do my injector cups and no questions asked and withing 2 hours they arrive at my shop and preform the job. forward 3 hours later the truck is assembled again and we ran it on idle for and hour and beleive it or not….still getting water in diesel!!! so i call jorge back and these where his exact words lol “ i tried explaining to you but you kept yelling over me on the phone…its simple change your fuel doser” so i did. and beleive it or not problem solved..a problem that not even my mechanic could pinpoint out! i have since apologized to jorge for my rudeness and we are on great terms now…this guy does heads and other things amazingly but beleive me when i say this, his strong point is his knowledge in diesel engines, i have taken several heads to him to preform work and let me tell you he has by far the cleanest and best work in california hands down! but the thing i like about this shop the most is that no matter what, their one phone call away from helping you out in any situation you come across!! they have 5 stars from me any day!
