Thanks for that info - I will look forward to that page you offered to e-mail me. I think that will help me figure it out.

I did not add any of those washers in there, because I was thinking they were for a different engine. Yeah, the bottom of this filter has a larger hole than the top. Actually, it will only go one way due to this. I slid the filter down into the canister and I just then simply put the cover back on- then put the bolt on and tightened it. I still have those washers though - I think there were three in the package, but I have no idea which to use. Without them, everything seemed to fit securely - if not- I can simply remove the cover and place the washer on top there if necessary.

I think it must have an anti-drainback because as mentioned - the old filter I removed the first time was holding in oil, but this cheap one that I installed 1000 miles ago was not holding in oil when I removed today. I think that was my problem all along - causing the noise at first startup of the morning (I do not recall it doing it before) and the knock today when I started it without oil in the canister.

Thanks again.
