Installed Sniffle Valve, Oil Drain and Air Intakes

I installed the sniffle valve in the aft port in the intake manifold (the upper brass fitting).  This is a check valve that opens when on the ground to allow excess fuel or water that leaks into the engine manual to drain out of the bottom of the engine and onto the ground.  I also drained the preservative oil out of the engine and installed the quick drain plug into the sump and safety wired it.

I then mixed up some proseal and attached the air vents to the side of the fuselage.  I drilled a couple of holes for alignment purposes.  I’ll fill these in later with some filler.  A lot of builders pop rivet these on, but proseal is tenacious stuff and will hold these quite well.  This is the left side.

…and this is the right.
