yes it is, but makes the job exponentially harder, the wiper motor is only four little screws, no need to disconnect it, just unscrew the whole assembly and lift it up and to the side as far as it will go. Personally, I just take it off..but..don't lose that clip! The valve cover will not lift straight up, no room, you will need to rock it side to side, and it will eventually clear and come off while tilting it to the PASS side. If it really will not come off, bump the engine over until the rockers on #6 cylinder are at their lowest point. good luck, gz
