Oil filter bypass valve location?

[AdamP]

Hi there,

Today I was doing an oil and filter change on a 2003 Boxster 2.7 I have. When I removed the filter housing there was a spring loaded valve stuck in the end of the cartridge, but I didn't take notice of which end of the cartridge it was inserted into when I removed it. I thought it was in the top of the cartridge, but when I offer the cartridge up the valve doesn't really mate to the pipe that feeds the oil into the filter, so I now think that perhaps it should be the other way around so that the valve is in the closed end of the filter housing (the bottom). But, thought I should check to be sure before I proceed.

Any help will be most appreciated.

Thanks in advance

Adam
