Aah.. I get it..
You know, having seen inside many motors in my time, I will tell you that especially concerning modern engines, that they are incredibly reliable and strong.. There is a misconception that running an engine hard destroys it, the reality is that the machine is designed to do it. It has been designed to rev to whatever it revs to. Most engines have rev limiters fitted and as long as the oil is at operating temp and it has good oil and a full radiator, it will do the mileage. I remember a good few years ago, we had a crazy mate who had a 1600 citigolf. This thing was always at the red line. He drove it like an absolute maniac. We had been building a bigger motor for the car and when it was ready, because we built as he had cash, the original motor which had been ringed, had 60 000 kilos on it. We fitted the new engine and out of curiosity, stripped the original one. I have never seen such a clean engine inside.. Rings were nice and free in their grooves, piston measured correct, ring gaps were like new, even the sump area was like new. The exhaust valves had a thin layer of carbon on them and the inlets were shiny like new ones. The tops of the pistons were so to say, discolored with carbon..
Compared to many engines that I have opened which had been driven gently, this was by far a better sight than the nursed ones..
Just for interest sake..
