Dean and I reassembled the oil pressure manifold and used the correct Permatex sealant for the threads. After the last engine run the manifold was leaking because I had used Permatex gasket sealer which did not seal properly. Next, we installed the skylight. We used Butyl tape to seal the window in the back, and over the ribs. We used stainless 8-32 bolts on the back of the window and aluminum rivets on the ribs. Looks great.
