ok before i break this how does the crankcase vent {the big plastic piece not the hose] come off just twist it which way ? i want to extend the tube after i finish the injectors and adjust the valves also 8- 18 or 10- 20 on the valves?

lefty, loosy. try an oil filter wrench. Tried to loosen mine the other day and could not do it with my hands. I didnt try very hard though.

Yep, what dripley said. I had to really get on mine to get it to twist off. Valves are .01 on intake and .02 on exhaust.
