what size are the lower exh manifold bolts? i cant get them off with the 13 or 15mm sockets i have, but yet i dont have a 14mm.

Also, is it normal to have greenish brown sludge in the valve cover and covering the entire head? No? i didnt think so... it might be time for a swap.

 

When I was doing my swap I could almost swear that I used nothing but 10,12,14, and 17 mm sockets for the entire thing.. so try a 14, honda must like that size.
