    Subject: Re: Detonation
    Do you have a oil filter on this engine? Here is the reason I ask. A number of years ago when I had a HS6 260hp engine on my CJ, the Chinese exhaust stack burnt off near one end. In doing so, it melted the "rabbit ears" of the alternate air into the carb. Being at an airshow Dough over night-ed one to me, so I could fly home. There as I was repairing the rabbit ears, I noticed gobs of solidified melted aluminum on the intake screen at the carb throat. That's when I realized that molten aluminum had been ingested into the engine. (It ran just fine by the way) I than opened the oil filter (10 micron) and found it filled with silvery aluminum sand. We than did a compression check which turned out normal (mid 70s). I drained all the oil, put on a new filter, and test ran the engine. I opened up the filter and found some aluminum sand again but nothing like the first time. Again I drained the oil and new filter and again test ran the engine. This time NO aluminum at all. All this time oil pressures and temps were normal. Lucky? I guess so. I flew another 100 hours on that engine before going to the M14P. These engine are very tough. One cylinder on my M14 came from the factory, with the wrong ring in place of the oil ring. It ran 438 hours! before the piston lands failed. I think Brain might be correct, you may have gotten some FOD from someplace during the cylinder change. From what you describe, it may be steel material of some kind. Question - were you able to account for ALL the piston rings or their parts, during disassembly? Also, have you checked the check valves on the cylinder for the start air line? If you did get some kind of FOD though the induction system you might bore scope the super charger. You should be able to check for possible blade damage by removing on of the intake tubes. Good luck. Jim "Pappy" Goolsby In a message dated 6/16/2011 10:53:03 P.M.

There was some pitting on what had been brand new chrome top pistons. When I pull the plugs again sometime next week I'll try to get pix off the bore scope. Did not buy the one that would do photos. Need to read my earlier post on this saga. What you don't see in the plug picture is what the element looks like on the Surface under 10 power magnification. It looks like it got hit with with #8 bird shot. Mottled or copper kettle appearance would be another description I don't think man's hands with a screw driver but or a wrench would make that appearance. Not unless they beat the element down with a meat tenderizer mallet could it look that way. Come to think of it, the inside of the #1 cylinder sleeve looked that way too. Instead of the expected smooth silver appearance it was speckled on the inside. Sounds like FOD that came through the induction system. Time to tear down the engine. -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 _brian@lloyd.com_ (mailto:brian@lloyd.com) +1.767.617.1365 (Dominica) +1.931.492.6776 (USA) (+1.931.4.WB6RQN) (http://www.matronics.com/Navigator?Yak-List) (http://www.matronics.com/contribution)

    Exactly. I just had that 3weeks ago. New g meter, no more noise. Or you over "G'd" the airplane so hard that it broke. Of course we would be talking abo ut you instead of to you. I'm glad it's a bad unit. If the meter works, the c annon plug will fix it. Bill On Jun 17, 2011, at 2:40 PM, "George Coy" <george.coy@gmail.com> wrote: > It is coming from the front G-Meter.
