I was watching Fast and Loud which is a TV show where they purchase classic cars, fix and sell them. Most often than not, they always find something wrong with the engine and it has to be rebuilt.
So they send the engine to the same engine rebuild shop and it always comes back and immediately fails. For an example, they got the engine rebuilt for a pontiac trans am…and after test driving it, they found out the engine cylinders were scored and there was metal in the oil.
Is it the same in reality? Is there a high chance a rebuilt engine will fail?
