I once broke down a mile from home. The fuel line was clogged. I used a sports drink bottle as a temporary fuel tank. I zip tied it under the hood to the fender and cut the fuel line and inserted it into the bottle. I drove home and fixed it correctly.
I welded a cam plug in the end of the camshaft on a small diesel motor in a tractor after taking off the front cover. I attached the ground clamp directly to the cam to prevent arching across the cam bearings. That engine is still running strong.
My grandpa tells stories in the model t days that would make the safety guys heads explode. They could not afford antifreeze so they used some sort of alcohol.
When it was cold out, they would take a pan of hot coals from the fire place and put it under the engine to warm it up before hand cranking.
His model t needed crank and rod bearings frequently. They used strips of pig leather as bearings.
