This is simply a case of the most basic tenets of aircraft maintenance and inspection being ignored, in lieu of shiny polished aluminum, esoteric engine modifications, and operational hubris (or ignorance).
There is NOTHING that will kill you more surely then slop in an elevator tab, and few...
The Soviet Bloc M14P radial aircraft engine uses a Compressed air starter. The reservoir tank charges up in flight after engine start, but if for some reason it fails to start, you can pump it back up by hand. Used to be a guy at the airport that has a Sukhoi with one of these things in it.
This is from 14 CFR part 1: ( I'm assuming a USA registered aircraft )
" Major repair means a repair:
(1) That, if improperly done, might appreciably affect weight, balance, structural strength, performance, powerplant operation, flight characteristics, or other qualities affecting...

Obtain a suitable test club prop.Typically short span, wide chord, and coarse pitch, compared to a "real" propeller. Shroud it. Obtain an electric motor, use the motor to drive the prop so some n rpm. Measure the electric load required to do so.Do the math, and you have the HP needed to drive...
Most of these bolts have a radius under the head. make sure what ever hardened washer you use, has a corresponding radius, or relief to accept it.

Design some sort of augmenter exhaust system to use the velocity of the exhaust gases to extract air from the low pressure side of the engine.

I've seen two failures in the field, both MS21042-4. The bolts were loaded in shear, and the torque putty was still intact. Scarey stuff when the helicopter drive train is full of this stuff.

select the various FAA-H-8083-XX manuals. Very large PDF files.
If you are an AME, you are a mechanic. Not saying it can't be a hoot, (I have a degree in Mechanical Engineering, but have been a mechanic for nearly 40 years,) but STAY IN SCHOOL and...
"Of course the cumulative result of the blowby was a noticeable volume of crankcase fumes out the vent (no PCV)"
I had a similar run out engine (in an econoline van) that I simply vented the crankcase vent (disconnecting the road draft tube) to a 1 gallon clorox jug, loosely filled with teflon...
Piper Aircraft used aluminum wiring in a ton of models, back in the 1970's. Primarily in the larger power wiring, battery to Buss, Ground & starter cables, & so forth. Piper SB836A required inspection & replacement, but apparently it wasn't serious enough to warrant an Airworthiness Directive. I...
