I had to take both of mine off and retorque/overtorque them. I used the gaskets that came with the kit. One right after I put them on and one a few days later. They always seemed to ooze a little bit of oil until I replaced the gaskets with rubber ones. Once I put the rubber ones on they sealed and never leaked, with the proper torque. My anti drainback filters leaked down too, so it took a lond time to get oil pressure. After my cam broke and I replaced the engine and put on new filters, I had oil pressure in a second and a half. Now I am happy and would recommend them to everyone.
