'Michael,
I know of the mod, Tom Goodlett of Alverado, Texas created the Machine
Templet to drill the pistons. I believe Ed Wegner has a set also. And I'm
pretty sure Ed's 440-C5 has the mod. I don't see a problem with doing the
mod. I do not believe in doing the Olds Ring installation. In fact, I'm going
to pick up a spare 440-C5 this Dec. The person that did the overhaul
attempted to get a snug fit with the Olds rings to reduce oil consumption,
well it worked, right up to about 5 hours and it made metal. I will do the
mod to the two engines that I'm going to pick up and overhaul. The rest of
the engine will be stock, with minor clean up on the flow. To me oil is
cheap, if you can't afford the expense, find an airplane with a brand new
shinny flat Lyc. The Ranger was designed to use oil, fact. Two qts an hour is
OK with me. I get a kick out of seeing these young kids with there shinny new
spam cans watching me do an oil change/refill on the flight line. So what if
I start off with a case of oil under the rear seat, it only gets lighter as
the trip continues on.
As for documentation, I would be careful doing the logbooks. What the FAA
does not know will not hurt them, but you did not see me write this.
Take care,
Give my best to your Dad. Any word on Carl's PT. Marshall Freidman is in love
with his 24W46 that he got from the estate. Just going thru the dial mode on
the Aeromatic.
