      Filter Screen perfect fit, Gasket is useless

      Filter Screen perfect fit, Gasket is useless

      Submitted 2018-04-26

      By TimInSalem

      From Salem, VA

      The Filter (really a screen) is a perfect fit but the pan gasket that is provided is awful. I put permatex ultra grey rtv between the pan and the gasket then assembled to finger tight (ultra grey just starting to ooze out) and let sit for 2+ hours. Then as I torqued to a first step of 40 in-lbs (70 in-lb should be the final torque) following nissan's torquing sequence, the gasket slid out between the bolts. I checked my torque wrench against a friends and it was calibrated correctly. I disassembled cleaned everything and tried it again. Same result. Either this gasket is too thick or too soft. It has wasted a lot of my time. Ended up getting Nissan's gasket. Worked perfect.

      Bottom Line not recommended
