    The metal built up on the ring is from the transfer to the cylinder wall.. its not bad... a hone will take it out.. melted aluminum scraped off the wall by the ring... most of the "melting" is low on the skirt.. I'm sure its not a mixture issue.. the top of the piston is fine along with the head and valves.. plugs all look good. this is a service bulletin from ford about oil pumps http://www.oldcarmanualproject.com/manuals/Ford/1932/pages/p_%2067_jpg.htm Jeff Read this topic online here: http://forums.matronics.com/viewtopic.php?p=404363#404363

    I was thinking a lot about oil pressure too, but was thinking about my tractors that do that a lot as well... but then... air plane usage means you're using all the horsepower available, all the time (unlike my tractor in "retirement" mowing mode). The weakest point is going to go first, and that must have been that cylinder. Water cooled engines run less piston/cylinder clearance than air cooled, it must've just got hot enough to interfere. You mentioned it wasn't getting quite up to rpm prior to the failure, must've been the start of the event. Happy to hear you can merely hone the cylinder to get it back to good. What kind of cylinder hone do you use, a parallel rack and pinon stone, exanding parallel stone or ball? I'd recommend the first, which will enlarge the cylinder more, but maintain perfect round. The increased clearance won't hurt a bit. Most manuals don't recommend reboring until your in excess of 0.008 clearance if the cylinder is within taper and out of round specs (which are FAR less). I'm thinking more might be better running these in airplanes. Probably do need more oil pressure, especially if Ford recommended it for cars back then. Water temp wouldn't likely have showed the problem very obviously. Glad to see you found a likely smoking gun. Read this topic online here: http://forums.matronics.com/viewtopic.php?p=404372#404372

    Subject: Continental Conn Rod Bolts
    From: "tkreiner" <tkreiner@gmail.com>
    If you have a small Continental, i.e., an A or C series engine, even an O-200, this may be of interest to you. We're offering this to the Piet list members first, EAA 302 members second (my EAA Chapter), and plan to list any remaining items on eBay after OSH. Continental P/N 530213 is the replacement Conn Rod Bolt for all of the above referenced engines (also used on some engines that are quite a bit larger and generally not used on a Piet.) My IA has recommended that because I don't know the history of my engine... it would be very wise to replace these. About half the bolts are packed in the paper/foil US procurement bags, and are NOS items from Fed Surplus. New, unused, unwrapped. The other half are in single bags, and/or unbagged, as we've opened a few to see what was inside. After a net search, we've found that the sellers with the $12 item cost generally don't have stock... and the most available parts are around $16 each. Since the sealed bags hold 10 pieces, we're offering them for $100., which is only $10. per bolt. The loose bolts will also be the same cost. I will be prepared to bring these to Brodhead, to save on shipping costs, if you're interested. Supply is limited, so if you need any, PM me ASAP. -------- Tom Kreiner Read this topic online here: http://forums.matronics.com/viewtopic.php?p=404399#404399

    Subject: Re: A engine out
    (preamble),I'm no expert but, i have seen a lot of blown-up engines. the piston in your motor has damage consistent with preignition. the pinking,detonation,causes the ring land to collapse. trapping the ring. typically,when you have a bore that is too tight, the seizure is more symmetrical than yours.often these are referred to as having seized "four square" as the damage starts at the sides of the thrust faces. did the damage point at the exhaust valve in the block? if not then you should check the rod for straitness . you should anyway, along with whether or not the rod is centered and not side loaded anyway there is a lot of inspection to undertake before reassembly. thats my two cents worth.just glad you didnt get hurt!.

    Subject: Re: A engine out
    From: "Pietflyer1977" <rob@stoinoff.com>
    I had the exact same thing happen to my Model A. Looked just the same. The other 3 pistons were all in the beginning stages and were not far behind the first one. After getting apart I found that the piston to wall clearance on a A is only .002. And seamed way to tight to me. I had all my cylinders honed out to .004 for more clearance due to running hard for a period of time. But after thinking about it for a long time because I never really knew that caused it, it was really bugging me. And I got to thinking one night that with all the trouble I have on a daily basis with China made parts in my business I wonder it something is up with the new China made pistons? ( that is all you can buy these days ) Maybe the alloy is not right and these pistons are not expanding etc. at the correct rates? My opinion is that something is up with the new pistons ( maybe not ) but I just don't know. Haven't ran mine again yet but if I was you I would search high and low to find some NOS parts to rebuild your engine. Hope you don't have any more trouble and would like to hear progress reports of how it's going. Read this topic online here: http://forums.matronics.com/viewtopic.php?p=404430#404430

    Subject: Re: Wings ready for primer and paint
    From: Ken Bickers <bickers.ken@gmail.com>
    Chuck, here is another picture of one of the wings while still in the rotator stand. The vertical post of the rotator stand is one inch wide, which offers a way to get a rough measure of the depth of the airfoil. Also the under-camber of the Pietenpol airfoil is very apparent.

    I'll be there in my Piet. I think Shad is planning to go too. For sure I'll be there Saturday. If I get very ambitious I'll take my son over Friday and we'll camp out. A few years ago there were 6 Piets there! If the weather is good there is usually a decent turnout. Good grassroots kind of flying! Keep in mind Frank Pavliga keeps both of his beautiful Piets there too, the Rudolph Piet and Sky Gypsy. Also he has the one and only flying Waco Nine there. It is beautiful! If you can make it, come and look for the green Piet and introduce yourself. Don Emch NX899DE Read this topic online here: http://forums.matronics.com/viewtopic.php?p=404439#404439
