I fabricated and installed the crank case vent tube. I may add a catch can at some point. See how much blowby I get. I then worked on an oil leak on the bottom of the engine. The other day I noticed some drops of oil on the chrome domed nuts on the sump plate. I drained the oil and pulled off the oil cooler .. then removed that plate, cleaned it all up and put it back on. This time I used the stock self locking nuts instead of the domed ones. I then spent some time with one of the guys at the airport on how to do the fiberglass work to cover the countersunk rivets on the cowling. He's going to take me thru the process on one of the hinge areas ... then I'll do the rest myself. I haven't worked with fiberglass before.
