I've stripped and cleaned the PRV. It looks good as new.
Timing side bush:
I set my internal callipers to lightly touch inside the timing side bush. As I said yesterday the bush feels consistent all around. I measured the callipers with my brand new 1 to 2" micrometer and found a measurement of 1.3750". The crankshaft journal measures 1.3732". I make the difference 1.8 Thou.
I did not detect any appreciable ovality in the crank journal.
Big end journals, measured North to South and West to East:
Timing side, N/S, 1.4495", W/E, 1.4492"
Drive side, N/S, 1.4498", W/E, 1.4498"
What do you think about all this?
