when you say cam seal, are you refering to the cam end plug that is on the distributor side of the engine that you can see on the outside of the engine? If so you don't have to remove the camshaft, when i did it mine was spewing oil on my trany so I removed the valve cover and took of just that very outside cam holder an torqued back to spec. the local acura dealership assured me i didn't need to loosen all of them and torque in pattern. Just remember to use a very thin layer of ultra black all around that seal. It might feel loose just let it dry. I did mine in the evening when i didn't plan on going anywhere.
