Hi all, merry Christmas! I was wondering if any of you might be able to help with a missing part which it appears is NLA.

According to the parts catalogue, a small seal 605169 sits at the bottom of the inside of the oil filter holder beneath the oil filter cartridge RTC3183. I don’t have one in my car, and I have 3 genuine oil filter kits RTC3183 but they only include the top seal.

Any ideas what I might do? Is it really necessary, or doesn’t it matter if it is MIA? Does anyone have one on hand that could measure the dimensions for me, so I can see if I can find something appropriate?

Cheers, Matt
