What's the big end wear limit on a S7 de Luxe engine?
Please don't say 3 thou.
I saw someone quote the max allowable oil clearance on the big ends is between 1 and 2.5 thou. So I'm screwed if that's the case. I'll need oversized bearing shells and the crank will need turned down.
The pressure bypass check valve looks good. I tore into that, and saw that it was clear from blockages. There was something that looked like a hair in there, but it didn't seem to be up in the ball... just wrapped up in the spring. It seems to hold pressure in reverse, so I'm calling it good.
