I changed my oil and filter this last week. I had bought several filters at one time years ago so I thought I was ready to go. I really can not believe these filter manufacturers would sell these car specific kits WITHOUT putting those two tiny O-Rings into the kit... it has the copper washer for the drain plug.... the oring for the top of the filter canister... but NOT these orings.
I am dealing with a Honda brakes and transmission at the same time... so I went to the Van's in Austin ( taken over by CarQuest) and it has a Carpack in the same building.
They could not find a number for these rings.... so had to find it by size ( thanks to the forum I had that written down ) ... they had them... but they are black. I would be worried about a generic oring from Ace Hardware.... but am hoping a 'car place' when asked for an oil oring would only have the proper type rubber orings to give to customers... but the statement about green or brown worries me.... is Viton not available in Black ?
I hope more discussion and information will be forthcoming in this thread.
