Biohazard

Good thing you are not paying someone to do all the work for you.

This would be unpossible. Daddy's pockets don't go that far down. If I wasn't able to wrench, I wouldn't own this thing.

Solved on the valve seals: The larger ones are for the intake side. They offer better sealing because the intake side is under suction while that valve is open and the cylinder is inhaling. The exhaust side doesn't have to try so hard to keep oil out because as the cylinder is pushing out exhaust, it puts positive pressure around the valve stem. Looks like someone installed intake valve seals on all valves in my motor and, let me tell you, they are so hardened that they feel like black ABS plastic. I'm certain that they seal like crap.
