Hi i am in the middle of doing the longest oil change of my life! I can't get the screw top off the canister holder for the oil filter, its a 2001 so its the element replacement type as oppose to screw on. When i am trying to turn the nut to get the top part off the whole thing is turning at the block, i have been going at this now for 2 hours and all it does it turn at the block end the cap itself isnt budging any ideas i am pulling my hair out!!!!!!!!!
