I am doing a PI Intake Swap and when I looked down into the intake port, I noticed a lot of debris on the outer part of the valve. It looked almost like oily dirt that kind of has a sparkle when a light hits it. Anoyone have any ideas on how to clean all that out without taking the heads off? I have tried rigging a rubber tube on a shop vac but no luck. Any help is apreceated
Thanks
