There are so many tools I’d like to have but like John I’m not 40 anymore. Kim
My dad, my brother and I share the oddball stuff like this, tools that are handy, but have a limited number of uses. In this case, my dad's had the same one he bought in the 80s working at the dealer. It's easier to justify buying an oddball when the number of potential users is 3x as much.
I might get hammered, but that's fine with me. I don't make a living wrenching on other people's motors, only mine. That said I have a bunch of Harbor Freight tools that have served me and my friends well. Pilot bearing removal tools, bore scopes, bearing tools, front end tools, yada, yada, yada. I know it's cheap Chinese junk, but when it's raining or snowing, I whip 'em out instead of having to make a tool run.
Here’s one of those Dorman screw-in copper plugs disassembled and the instructions on how to install, for those that want to know. 7/8” hex to hold the plug, 1/2” hex to tighten the acorn nut.
Those are cool! Ive never had a plug blow out, they just rust out from water as coolant. My 351C '57 Ford was a leaker and it finally became a large leaker. When I uses a screwdriver to pry what was left out in the parking lot, it was very thin. Brass is the way to go but proper coolant would have prevented that on my part. It was a junk yard core short block so who knows what condition those were in when I bought it...for $100 pulled! Yeah, 1993. Harbor Freight, home of the disposeable tool! Hard Line bender worked 2x, broke the handle on the 3rd bend (in a vice) took it back and got a new one. Have not had to use it since.
The block heater idea is a good one. They clamp in secure.
