Advice for all you car people!

I am a self taught old school mechanic. I had to learn the hard way. Many times without a service manual or anything in black and white. No factory type tools to do the job either. Just good old engineuty. We could be stumped on lots of things that no shade tree mechanic b4 us ever did other than at the dealerships. The little town I grew up in the line mechanic only worked on Chevies. He also learned on his own. I only got my journeyman’s certificate in 1995 as the Canadian National Railways required that I be a journeyman to work on their trucks and equipment. Kim
