On preflight I noticed a little oil seeping around the bolt on the
pilot's front cylinder (Superior Milleniums). This is on a '67 C150
w/ the Continental O200. I grabbed the bolt and turned it @ 2 1/2
times until it was finger tight against the cylinder.

Partner and I have grounded the plane. The gents hanging out at the
FBO say, put a wrench on her and fly the darn thing. We'd prefer to
stay safe, legal and alive.

Anyone else experience this and what am I in for? Thanks folks.
