In a heavy duty engine one would look for blue smoke comming out of the exhaust pipe on trucks without a diesel particulate filter. another sign would be excessive blow-by causing the engine to run hotter than before. low power and low engine oil level could also be tell tale signs. but the biggest giveaway is if your oil sample comes back showing excessive chromium and iron in the oil.
Blue smoke out the tailpipe--lots of it. If its a blown ring seal, then the oil is being "blown" into the air cleaner, burned up and out the exhaust. Also, the engine oil level will be next to nothing.
A blown piston ring is a major mechanical problem. The easiest way to determine this is by checking on a bluish tint of the exhaust smoke.
There are o-ring seals at every line connection.
Bad valve? Broken piston ring? It could be a broken valve, but you would have other signs if that were the problem. Most likely it is nothing more than valve stem seals being bad.
You mean a piston ring. It seals the gap between the piston and the chamber in your engine

The Chevrolet 350 stock "O" ring valve seals attach to the valves not the heads but, yes the head assembly has valve seals.
Poor piston ring sealing in diesel generators can be caused by damage or misapplication. If a diesel generator is left running under a low load it can cause poor piston sealing as well.
some animals are ring seals, polar bears, harp seals, leopard seal and some others.

yes, you can use the umbrella seals. I just replaced my umbrella seals on my valves with new ones. My head gasket kit came with the o-ring seals though, I heard the umbrella seals were more preferred. I haven't had a issue since I replaced them.
