DieselTechs is a resource for those who are currently employed in the diesel maintenance field. This subreddit's mission is to become the best place for technicians to help each other with such things as:

rare, puzzling, problems that can't be diagnosed properly. e.g.; "anyone ever run into this before?"

advice on resources to help us further our careers. eg; "Can anyone give me advice on ASE certs?"

Help with job hunts. eg; "Our shop can't fill a position, who lives in Oakland?" or "I'm moving to Oakland, anyone know who's hiring?"

This definitely IS the place for medium and heavy duty techs. we want all of you: Marine! Truck! Transit! Coach! Generators! Heavy Equipment! We also encourage questions regarding support systems, too - e.g.; air brakes, outdrives, transmissions, whatever!

SO MANY RULES!?!?! This is to prevent traffic from leaving other, awesome, subs out there! Hey, check some out:

At this time, no restrictions will be placed on who or what will be submitted, but posts should be from a current diesel technician with a question. Once again, there are a lot of other subreddits out there for "check out my rig!" or "Lol, look what this customer did to his turbo!" or "which is better Cummins or Powerstroke?" so please submit them to the appropriate places. Flair and Verification coming soon.
