Oil pressure relief valve, crush washer change Options

[TheCabinetmaker]

I've never had one leak before, but this one does. The gasket kit came with a flat aluminum washer that I used. Yesterday, while looking in my gasket box for a distributor shaft seal for my car, I found a oil valve crush type washer. My Q is: Is there oil in the relief valve cavity or does it drain back to the bottom of the case? Do I have to drain the oil to change the washer?

Thanks.

Thanks Brant. It just barely seeps so I'm gonna wait till his 500 mile oil change and do it then. I actually found three of the alum crush washers, but my local parts guy told me there are three different ones. Alum crush, copper crush, and solid alum. He said they are different thicknesses wich affects the tension of the spring. He can get all three. Hey wait a minute! You have a six. Are they the same?

Btw, Are you gonna do the vintage at Hallett this year?
