I am going to be doing my valve seals this weekend and I was wondering what size compressor I need to use for the air fitting thing. (I dont know the correct name, the thingy that plugs into the spark plug hole and keeps the valves from dropping into the cylinder.) I have a little home compressor, but it probably maxes out at 50 psi. Thanks for any help...

 

I just use a compression gauge hose (screw in type) and take the valve core out of it.

It doesn't take much, all it's really doing is keepoing the valve from falling in. If you do one cylinder at a time, and turn the crank so that the piston comes up to TDC of the cylinder you're working on, You won't drop the valve anyway ( at least not past the point of no return!). You'll be OK.
