Brief Description: Manfold pressure, engine vent, ring gear
Fabricated and installed the crankcase vent tube, and added a "whistle hole" for venting just in case the bottom end ices up, as described by some unhappy pilots with blown engine oil seals.
The whistle hole lines up with the blow-by of the heater duct, so it should always be nice and warm.
Added a TS fllightlines hose to the #4 Cyl primer port for the MP gauge.
Started to set up the ring gear for cowl fitting; bolted it in place with temporary bolts. Also check it with the slightly longer fan belt, and now the clearance is good between the prop oil line and the alternator case.
