Speaking of frozen engine parts, here's a true story:
In 1975 I bought a 1969 MGB that was in terrible shape. Friends and family told me I'd wasted my money, somewhere around $300 if I remember correctly.
One of the problems was that the pistons were rusted in place. I took off the engine head and skillfully freed the pistons by sticking one end of a couple feet of 2 x 4 into each cylinder and pounding on the other end of the 2 x 4 with a sledge hammer. The section of 2 x 4 was about 3 feet long, long enough to stick out above the open hood.
When all 4 pistons were unfrozen, I made a reasonable effort to remove as many wood splinters as I could from the cylinders. Then I bought and installed a new head gasket, adjusted the valves, etc.
Never could understand why that car burnt so much oil. I got about 20 miles per quart. I'd buy "recycled" oil from the Arco station in 5 quart jugs.
That was only one of the problems with that car. I had to tear up the battery compartment, which was inside the car under the nearly non-existent "back seat" in order to install a 12 volt battery because I sure as heck wasn't going to pay the ludicrous price for the twin 6-volt MGB batteries.
Straightened a bent distributor shaft with elbow grease.
Then, some lousy slob behind the counter at an MG parts store convinces me that the manual transmission could use SAE 50, when the Chilton manual that I'd read said that 80 weight oil was needed.
All that creative low-cost work I did to get the car on the road, and the transmission ended up destroying itself because it had the wrong oil in it. 41 years later I still can't forgive that guy behind the counter.
As long as I'm bashing people who chose to sell me what they had when they didn't have what I needed, shoe salespeople from 1967 to 1980 also incur my wrath. All that time, they'd sell me size 13 and tell me that's what size my feet were. No, my feet were bigger than that but 13 was the largest size they had.
Try to imagine wearing shoes 2 sizes too small for almost a decade and a half, then think of the relief upon realization that you weren't going to take it no more! My, I sure acquired a far rosier outlook on life after I measured my own foots and managed to get a pair in my size via mail order. (Retailers just didn't have anything over 13.)
Whew! Guess I was feeling chatty!
