When building my Rocket I made a plenum to assist with cooling. To provide access to the dipstick I put a cone around it, and then attached some scat to the plenum directly above the cone. When installing the plenum the scat is compressed down around the cone - this maintains the seal around the dipstick so the plenum does not lose pressure.
Now I want to install the CPI electronic ignition, and want to put the coil packs inside the plenum. However one plug boot interferes with scat.
My question is: Regardless of the electronic ignition, is there a better way to provide access to the dipstick when using a plenum? How have others done this?
Here is the top of my engine with the plenum off - the CPI coilpack is roughly in position:
Here is the bottom of my plenum with the scat attached:
