Help with Oil Pressure Relief Install

All,

I am currently trying to find the source of my sp 1600 / 1970 bug's
overheating.
After cleaning the oil pressure relief valve that was stuck, I find
that
when I put it back in, it still sticks somewhat at the top. After some
tapping it will fall out.
Is it supposed to be completly free and easy, or can it have some
resistance ?
Do I need to to more cleaning ?
And finally,
It seems to look just like the control valve, I thought the relief
valve
had a notch in it. Does it, or am I ok here ?

I did read all I could on this subject in the group, but could not
find the answers
to this.
Thanks for the help,

Trey.

It usually sticks a little, but oil pressure will push it down.

The notched type relief valve piston was only used in some engines
(1500sp?) the rest vere all smooth. (all dual relief cases had two
smooth pistons)

Jan,

Thank you so much. It just started dropping like a rock
so I guess it is ok. If I don't overheat I believe it should
not stick again. ( But what are the odds on that one ? )
