The Cessna  C182 is one of the best certified light planes in the world.
It will lift everything you can stuff in it and fly
1100 mile range with 90 gallons of gas. It can land  or crash at less
than 60 MPH which
makes it very safe. Low fatality rate on accidents.

It has been sitting for awhile with the re-manufactured 2000 TBO
Continental new engine with only 50 hours on it.
The old 1500 hour engine crankshaft had a mass of
cracks. It could have failed at any moment. The new engine
is 2000 hour TBO with double counter weights on the crankshaft.
I would average only about 500 hours on an exhaust valve and then
I would have to replace it.

The previous engine only had one counter weight. Nobody
has ever cracked a Mazda rotary e-shaft no matter what.
The Mazda rotary has the same .47 BSFC as the O-470 230 HP
six cylinder engine in the C182. The Continental engine weighs about 450
pounds.

The Mazda with cast iron end housings is about 325 pounds fire wall forward.

I am hooking up a an electric pre-oiler to the main oil gallery and
inspecting the cylinder walls
with a camera that fits in a spark plug hole. The walls are in fine shape.

You have to take good care of these things as a new one is $30,000 and up.

I had the idea of using the pre oiler pump to drain some oil out
of the engine pan. I did not want to pre oil pump a few gallons in and
over fill the engine.

It did not work. The pump did not suck well.
Typical of pumps in general. It is why Chevy put a vertical shaft in the engines
with the oil pump in the bottom of the oil pan. The Mazda pumps
are a bit on the high side  as well. I had a lot of trouble with the TTC oil
pump and never got it to my complete  satisfaction. Pumps
just don't like to suck.

So I had to take the bottom of the C182 cowl off to get to
the oil pan drain. Pain in the ass. Last time I took
the  lower cowl off I forgot what a pain in the ass it was.
I am surprised Cessna did not put a hose on it with the
drain fitting below the cowl. I can't do that as the airplane
is certified.  I could break the law and do it If I were
going to keep it.
