I will know better when I remove the valve cover. When I initially put the gaskets on, the leak was minimal. The second attempt was torque to 90 in/lbs. They leaked so bad I was afraid the oil was going to hit the headers and set the car on fire before I got the car home (I was 1 hr away). I even stopped and got a loan of a socket and ratchet thinking the covers were loose, but the nuts were still tight. By tomorrow evening I will have it apart, and adjusted in wait for a sunny day to test the change
