I am a pilot, so I think I can comment. I had some relatives by marriage killed in a plane crash. He was a non instrument rated pilot, flying in the fog, at night and flew his Cessna 172 into high lines with predictable results. A relative sued Cessna and won. Another relative by marriage was a test pilot for Cessna, he will tell you that lawyers killed the small aircraft industry. Its why airplanes are unaffordable, unless you are a tort attorney.

This is one of the best engine assembly videos I've seen. Inter-cylinder baffles should have been installed after torqueing the cylinders. It's not impossible later, but since the engine is on a stand, it's easier before the intake tubes and drain-back tubes are installed. Also, lube the oil filter gasket, DC4 silicone grease is recommended, before torqueing the filter in place.

They rotated the case before putting in the through bolts. Does that not allow a bearing inside to possibly spin?

Why is it ok here?

That project alone showed the complexities of automotive conversions.The PFM 3200 en.wikipedia.org/wiki/Porsche_PFM_3200 Aircraft engines have set timing, and are optimized to cruise at steady RPMs well below 3000 RPMs limited to the Propeller tip speed breaking the sound barrier. There is no need for a gearbox. All ICE engines function on the same basic principal of burning fuel to create an expanding gas to force a piston down and rotate a crank. You want Simple Reliable Low RPM power at a constant flat power band. Your not accelerating or shifting gears. There have been a lot of advances in the modern Aircaft engine, mostly metallurgy, electronic ignition roller tappets, and a few others. Considering they are Certified and certificated for a specific airframe, there is little demand to go through the costly process of a new STC to replace the original engine with a new design. Cessna build under 200 172's a year. The vast majority of single engine aircraft were built in the 60-70s. Of the 150,000 single engine aircraft registered in the US the average age is over 50 years old. A new single engine airplane is more that 600-700 thousand dollors.

Thanks. The two reasons I CAN think of (maybe) for doing this is that the rings don't usually seal that great until you seat them (a least old ring materials), and maybe it's an attempt to initially keep down total leakage by extending the path through the rings to the crankcase, or maybe to allow the ring gaps to seat initially in different areas for wear?

The two sides of the bearing (crank journal and inner bearing surface) actually ride on a "wedge" of oil so that the surfaces do not touch, called hydrodynamic lubrication. This creates a VERY long lasting bearing, especially one that gets hammered in use like rod and main bearings do, as long as no hard contaminates (metals mostly, inside an engine, from wear or breakage) are introduced and the oil is kept flowing at the proper minimum pressure. I think most of the wear that does occur on this kind of bearing comes during start up, as then the forces are held long enough for the "wedge" to break down, or enough oil to leak out of the joint for contact. Luckily, the loads are comparatively small during cranking, and the engine comes up to idle speed quickly once started. Sometimes roller type bearings are used for this application, but rarely. Non pressure oiled (splash oiled) motors use roller bearings more often, like weed eaters and simple lawn mower engines. Simplified, but hope this helps.

Theyre like realy thick shims rather than bearings. No moving parts ie pins, balls, roller, races or cases.

Tri metal bearings - stack of steel at the bottom, then copper in the middle, then babbit on the bearing surface. Babbit is an older alloy, typically lead or tin based. So they are plain bearings of a softer material that allow the hard steel crankshaft to ride on during start or low rpm. At engine speed, a film of oil is what the crankshaft rides on.

I was wondering why the magneto hold down nuts weren't safety wired. Anyone know?

Mike Burch good question, I was wondering the same thing about much of the hardware on this engine. In school I always heard “ torqued, cotter pinned, safety wired”

@@steveb7310 Yeah, I'm not an aircraft mechanic or anything like that but I thought there were a few short comings in the presentation. As you stated some of the hardware didn't look like what I thought aircraft quality should look like. On another note, have you seen the video here on proper torque technique? It's super informative.

Lock washers and torque. It would be near impossible to safety some of these magneto locations out there

Low volume, high variety (I/O 320,360 ect and all the ADs) make the costs go up. Add in the low demand and high liability and there you have it.

how many running hours will one of these engines last for? I want to make sure my engine is always as good as new, so please estimate the EARLIEST time for a complete overhaul. I don't want to wait for wearing down of parts to below or anywhere NEAR threshold tolerances. Don't want it to be ANYWHERE near worn. thanks in advance guys / gals.

Not the best idea. If you teardown too soon, then most of the clearances will still be within limits and will be re-assembled as such in an overhaul. Then some hundred or so hours later they are out of tolerance on your freshly overhauled engine.
