Cup should replaced, when showing signs of wear on seating surface. It is a good idea to grind spring so it stands straight up. It is also a good idea to lap in the cup to the block seat.


You can also get the Oil relief spring and washer with the cup by ordering ORK-100.

We now also carry an oil relief ball kit.
