You’re close. It’s actually a combination of both. Example: if a person’s car came from the factory on the tight end of the tolerance distribution, and said person regularly drives the piss out of the car when the engine is cold then there’s a high probability the engine will grenade. I thought the video covered both the tolerance and warm up issues. Apologies if it didn’t.
