What is the best way to find an engine serial number without using the data plate?

Can I bypass the oil cooler on my aircraft engine in colder temperatures?
Question for our engines expert: I have an RV-6 with a Lycoming O-360 and in winter, even with the louvres of the oil cooler closed, my oil temperature may only reach about 150°-160°. Can I install a shut-off valve to prevent oil flow through the cooler in cold weather, or does oil need to flow through it to keep oil pressure from getting too high?
Why is my engine running differently than most others?
I have had help from two different aircraft mechanics and they shake their heads. The don’t understand it. What is it with my engine that makes it run differently from most other engines? Have I overlooked something? Expert advice is needed.
Glass panel’s warnings worry aircraft owner
The old panel never yelled at me or gave me warnings, so to see the CHT hit 400 and then go yellow is unsettling.
Is a bad temperature gauge to blame for fluctuating oil temperatures?
I have a Cessna 172R and the oil temperature fluctuates from minimum to maximum constantly until shutdown.
What timing should I use in my engine?
Read this very carefully before taking any action: Remember, you’ll be taking more horsepower out of your engine with the increased compression ratio, therefore you’ve got to increase the engine fuel flow amount to support the additional horsepower. Failure to do this could result in severe damage to the engine and possibly cause engine failure.
Still hunting for why my engine won’t hold its RPMs
My 800 hour Since Major Over Haul (SMOH) Lycoming O-540-C4B5 engine won’t hold its RPMs. We’ve done several things to find the problem, but we’re still hunting.
Ask Paul: Finding the correct oil cooler inlet on my airplane’s engine
“I do not understand the the oil routing to allow the thermostatic valve, located in the filter adapter, to control the oil flow to or from the oil cooler, from ports not located on or near the thermostatic by pass valve.”
Ask Paul: Adding insult to injury
If an engine conversion to 8.5:1 compression ratio pistons was not approved by Lycoming, the conversion to 9.5:1 in your engine is adding insult to injury.
