Hopefully just sticky valves and not worn springs.

You allways see people viewing, but you rarely get any answer's, oh well here is a way to tell wether or not my ring's are ok.
I filled known bad cylinder with new oil around 5 pm yesterday, 2 hours later still full to the brim, and 13 hour's later (this morning) I checked it and it only leaked down maybe a centimeter.So rings shoul be in good shape.

I found out where brackets go:
I just brought front head in and had it worked on, machinest called and said head is ready $50.00 so I am asuming that the 80 psi reading was from a leaking head gasket and not a valve prob for that price/Allthough he has done other heads/flywheels/ and sold me clutch's, head gaket kits, and many parts before, so he may have just given me a deal, when I pick head up I will ask what he did to head..
