I get that English isn’t your first language and no criticism for that is intended, but whatever you’re trying to convey here is not coming through. Obviously the engine is damaged and the title states overrev, but no real explanation relating the two or much else either. In general the oil pressure needs to be raised for an S1 track engine, but it looks like there is more than that going on given the damage. Given that it is a reman there could be any number of possibilities on what the causes are.

 

My question also. Looks like some other things were going on. Was the peak rev logged?
