Jim, I'm not replacing the cam and crankshaft oil seals this time around
with regard to your advice on that subject. My air pressure line is an
Air-TAC HW 300 PSI (2608) line with 3/8 fittings. It's a fairly fat line.
It spread my original "cheap" 17mm impact socket. Spraying the crank bolt
with PB Blaster, hitting the bolt with a drift and hammer, then using a
new, heavy duty impact socket did the trick (150 psi), whew.
