Thanks, but the rope my wife ties around my neck is to short.Finally did some airplane stuff today. Most of 2020 was devoted to correcting and upgrading wiring in the house, shop and shed. Then installing the wife's solar electric system. I got that all signed off before Christmas and then rehung my gas heater in the shop. I had to take it down for the solar system because the old vent went through the roof where the solar panels mounted.
So I have heat in the shop again! I finished exhuming my big work bench this morning(I haven't seen the top of it in a while) and got my engine on the hoist and drained the oil today. Tomorrow I will start disassembling the little VW. I am going to do a complete teardown and inspection. I need to have Pops fly out here to supervise! I have room in the hanger for the SSSC, extra bedrooms and plenty of food. Nothing to stop him!
Just realized something. My 8 was a QB and I remember what a job it was running plumbing in the gear towers. The skin was on the fuse so had to work thru those little holes. No hide left on wrists...yours is of course no problem.Fab'ing up fuel and brake lines before riveting fwd fuselage skins on.
For those "professionals" that look down on all us poor hobbyist for using too many clecos, I'd like to point out the skillfully placed lower forward baggage bulkhead....
Very good chance that the rod on that piston is bent.I got most of the VW disassembled today. The timing gear and the rods are still on the crank but everything else is apart. The main and cam bearings are speckled with embedded metal chips and the main journals are rough. To be expected because the original builder stuck a valve in the engine while running it in his driveway. The head of the valve broke off and the piston hammered the valve stem through the top of the head into the rocker box. He got a new piston and cylinder and different heads and bolted it back together. He told me about this and gave me pictures of the damage when I bought the plane. My mistake was that it never once entered my simple mind that somebody would blow up an engine, stick new parts on it and not at least change the oil. He kept running it with the dirty oil and I bought it and flew it a couple hours before I changed the oil. It was full of metal particles. The screen caught the big chunks but there were plenty of smaller pieces that went through the screen. It didn't have an oil filter on it when I bought it. I have since put an oil filter on it and everything inside is pretty clean today so the oil filter did its job.
It turned out that I don't have a broken ring. It looks like the scratches in the bore were caused by metal chips embedded in the piston, probably from the broken valve. There are pits in the piston between the first and second rings that match the location of the scratches. I didn't find any chips in the pits so I guess they escaped somehow. You can tell by the appearance of the top ring that it is not worn in to the cylinder wall. The second ring is. Maybe the crankcase was pressurized because the rings never fully seated.
