Its smooth metal against one gasket that comes on the oil filter..

I guess its an O ring, but can it stick onto the car?

I do all my own oil changes this was done back in November now all of the sudden on 1-29-07 I notice in my rear view mirror a cloud of smoke behind me on the highway I pull over get out look under and oil is just pouring out that night I replaced the oil filter and oil just started it the next mourning ran 10min and checked and it looked even worse it was almost spraying out....



The almost 1000dollar repair was on another vehical 2000 Windstar alot harder to get TO the parts were cheap, labor was expenive. 185bucks fuel pump and all new coolant hoses 12 to 13 bucks
