Yeah the KA uses a rubber gasket set (2 peice). You will need a new one sooner or later, as they all harden. Mine started to harden and I noticed it durring the last time I swapped cams so I got a new one.
After that you can take the thing on and off for quite a while, just as long as you dont forget to rtv the lobes upon reinstall of course

The tech / employee price is about 19$ from a nissan dealership, or like 35 over the counter
