I am an amateur mechanic, but have done a great deal of very technical work. My only formal training is three years of high school shop classes, everything else I learned under or in a car. The newest thing I have worked on is a 2022 GMC Sierra. Seemed to be pretty much the same as my 2003 Chevy Silverado.
You are definitely correct about foreign (non-USA) makes. My wife had an Audi when we got married. I own a small toolbox of tools specific to her Audi S4 that I will never use again, but that was a 2006, so this issue predates 2013 for the makes that it is true about.
Admittedly, I try to avoid fuel injected vehicles. So I don't go out of my way to work on new things.
- dclowd9901 2y agoYou’re right, I was speaking specifically to euro and Japanese makes (I’m biased toward those makes, so I didn’t even think of qualifying it). I do a lot of auto work, between restoring cars to repairing my own. But modern fuel injection systems run on a razor’s edge of tolerances and often getting to some part requires dismounting a turbo, which is all sorts of pain in the ass, and not something I’d recommend for an amateur.
- calvinmorrison 2y agoYou say that but the new stuff is actually way more tolerant. Once we got electronic fuel, timing and spark in one ECU things totally changed. You want finicky? Deal with a solex carb!
- cout 2y agoI had a vehicle with a mikuni solex carb. It was easier to swap it with a Weber than it was to fix the carb.
- dclowd9901 2y agoHaha fair. I can even think of some like the continuous injection systems on old VWs
- calvinmorrison 2y agoAh dude those bosch CIS systems are hot potato garbage. I mean its a cool concept its just so fiddly. Once we got LH though things got a lot better. But that brings me back memories
- pard68 2y agoYa the cis/kjet thing is something I have always thought was neat and also am glad that the vehicles I buy and work on don't have them!
- calvinmorrison 2y agothey're neat and they're fine-ish usually once running but they're a fricking pain to setup especially since a lot of the OEM you are supposed to have don't exist anymore. Like the book says 'oh plugin this or that' and its just... yeah no sorry The only cool thing is the wiring harnesses and everything are fully analog so like, you have fuel injection mechanically, i mean that in itself is cool. it's just a pain
- pard68 2y agoI wonder how similar it is to a mechanical fuel injected diesel. All my tractors are diesels and they have electric free fuel injection. My tractors are something I always marvel over, besides the starter you don't need any power. I have an old Cat diesel that doesn't even have an electric starter! Uses a small gas engine (called a pony engine) to start the large diesel engine, and the gas engine uses a pull start, very similar to a lawn mower engine.
- calvinmorrison 2y agoDiesels never were carb'd - there's no venturi effect possible without vacuum. There's no spark. It's just totally different. They always have direct injection into the cylinder as far as I know. Maybe in the early 1900's they did manifold injection but I don't think so. It's just a total different concept. How the metering is done (IE How much fuel to meet load) though may have been similar, I am not sure. I 'asked a friend' on this one, since I am really unfamiliar with diesels in general.
- pard68 2y agoYa if imports are your thing you're definitely going to have a few tool chests of one-off tools! I have always stuck to American muscle and diesel tractors. The amazing simplicity of those machines has always attracted me. I love that I can hold a complete understand of the entire vehicle in my head. I'm sure you can even for modern vehicles, but they're not simple at all!
