Without privy to u20 specs, does anyone know what cylinder cranking psi should 
be for a healthy engine? I'm getting around 160 average and all 4 within 5 to 
10 psi of each other. Wet test shows a bump up of about 20 psi. Is this a tired 
engine or just normal wear. Trying to decide whether I should hone the bores 
and install new rings. I have no idea of the mileage.
    Thanks,
                  Tom
