On a side note to this.. I trimmed 1/2" from the oil dipstick standpipe to account for the engine mount thickness across the oil pan, so that the stock dipstick reads true.

I flew the plane today, and I have a new problem that
has cropped up.  I had some oil discharge from the
crankcase vent tube.

I have never had any oil come out of it before, and up
until a month ago, it was just hanging open.  I did
connect about an 18" piece of tubing to it, and just
have it sticking out above the intake manifold.

Today I made 2 flight, both were short, about twice
around the pattern and landed.

I had oil on the cowling inside and out after both
flights.  The total oil ejected was probably about a
cup, or cup and a half.

After the first time.  The oil was still right up to
the full mark, which is really over full, since the
mounting plate adds a half inch to the oil pan depth.
I am wondering if being overfull was the cause.

Originally there was a tube from the crankcase vent to
a fitting on the side of the filler tube.  It has been
just hanging open since I started flying, and has
never ejected any oil before.

Does anyone have any thoughts as to why this has
suddenly started ?

All temps and oil pressure are normal.
