Tompkins, P.E." Subject: Re: Engines-List: Aeroshell 100 Are you using 100 Plus? My understanding is that this is not a problem. The copper is in the oil anti-scuff additive and not coming from your engine.

I have not gotten around to doing oil analysis and I'm not totally convinced of the benefit...Will have to think some more on this as its about the right time to be doing it.

Piston pin bushings, rocker arm bushings, couple of idler gear bushings. Only other place to be concerned would be the rod bearings and if they are down into the copper, idle oil pressure with the oil hot will tell you that story.

I've been using 15w-50 for 15 years and never had anything out of the ordinary occur. I can fly all year long (highs of 115 and lows of 10; desert you know) on the same oil. I've got customers who fly 20 hours a year and customers who fly 200 hours a year. They all use 15w-50. None of them ahve ever had the sludge, rust, corrosion, or varnish problems my hangar neighbors have had using single grade oil. The multi-grade is still the best oil for the engine. -----Original Message----- From: tompkinsl@integra.net Sent: Thu, 3 May 2007 8:25 AM Subject: Re: Engines-List: Aeroshell 100 Are you using 100 Plus?

When I installed the nut, it locked up the whole impulse coupling mechanism. I took some measurements on the new one and compared it to the old one. It had been manufactured wrong. When I tried to return it (to Aircraft Spruce), I was given a run-around for 3 days. They wanted me to talk to someone in the technical department at Unison to see if I'd installed it in the plane wrong. They (Aircraft Spruce ) couldn't believe I found a manufacturing defect BEFORE it was installed. I made 30 phone calls to Unison over two days and never got a reply back. Aircraft Spruce finally just sent me a new mag (I'd already returned the first new mag). I got the second new mag yesterday. It's also F'd U. I called Unison 5 times yesterday without anyone answering my call. I finally got Aircraft Spruce to go through their supplier. Gee, they found out that pretty much all of the mags made since GE took over have been manufactured wrong. In the mean time, the next batch of mags is due in June. I took a bunch of pics showing the defect just in case someone wanted to see it. Sending them now to Aircraft Spruce. ________________________________________________________________________ from AOL at AOL.com. ________________________________ Message 6 _____________________________________ Time: 12:15:55 PM PST US From: "steve korney" Subject: RE: Engines-List: 4371 magneto I would like to see the pictures... s_korney@hotmail.com Best...
