I went to change my oil and the cover for the filter will not come off. I have applied so much force that the 26mm socket slips on the "nut". I started with a multi point socket (my first mistake, but it should have come off with that). I then got the low profile 6 point socket like you should have and tried that and it will slip off as well. I am a pretty strong guy and for the life of me I cannot get it off. Yes, I am turning to the left, lol. I am probably gonna have to JB Weld the socket to the top of the cover so it will not slip. I already have another one on order. I wonder if anyone else has seen this??
