Old Man with a Hat
Instruction video on 440 assembly:
· He sprayed WD-40 on pistons and rings. He does not recommend using engine oil on the rings, because the rings need to seat against the honing pattern in the cylinder bore. Oil can cause glazing.
I have always used oil on the rings during install. Has anyone else heard of using WD40 not oil?
· He says that rings rotate as the engine moves, so it doesn’t matter where the gap is when you initially install them in cylinder bore. However, in relation to each other, compression ring gaps should be 180° apart. The gaps should also be 90° apart from the oil ring and gaps. Thus, the gaps will form an X pattern.
Do rings really rotate as the engine moves, but keep the same position relative to each other?
What do you think on these 2 questions? thanks, Ben
