re: How many of you baws actually work on your own cars?

I do everything except for alignments, changing tires, transmissions and the few other things that require special tools where the cost to buy the tool is greater than the repair cost at a shop. I buy cars that need a few minor things, fix them and drive them for a few years until something better comes along. Ive never had a car note either.

I'm currently learning (thanks to youtube and my brother-in-law). I've done smaller stuff like headlights, alternator, and belts. My BIL and I are about to do a lot of work on my engine changing lifters, gaskets, camshaft and some other things to get rid of that garbage AFM system GM put in their trucks. But I still pay other people to do my oil changes

I do some things, oil changes (unless I get coupons for cheaper than I can do myself, which happens a lot anymore), brakes, and a few other things. I'm not a teardown and rebuild person.

I take care of the things that don't require special equipment to detect failure of parts like electronics and such. If it's a simply remove, replace, it's in my wheelhouse.

Fluid changes, water pumps, leaky gaskets, brake jobs, body and fender work, timing chains, exhaust.

Things that need multimeters or other diagnostic equipment to determine if good before replacing is out my wheelhouse. Once you buy some of these expensive parts, you own them whether you need them or not and that gets $$$$$ real fast.

Younger days I'd change my own oil, filters, plugs and other diy car stuff.

Now I'm afraid to open the hood
