A loose, improperly aligned or worn-out oil filter are common causes of car oil leaks. A loose or improperly threaded drain plug could also cause an oil leak to occur.
No, it will not cause oil leaks.
The most common cause for occasional, small oil leaks is a worn seal or damaged gasket. The leaks are most visible when parked but occur constantly.
Oil leaks will not cause an engine to heat or to seize. A lack of oil will cause it to get hot and seize which is caused by not checking the oil level and adding as necessary to keep it full. As long as the engine has the proper amount of oil it will run just fine. The leaks may cause a mess, waste of oil and money, but they will cause no damage to the engine.
crank seal
The most common place for oil leaks is the sump/crankcase cover gasket. A torn gasket will allow oil to escape. A common cause could be a blown head gasket putting too much pressure in the crankcase.
Only if it all leaks out.

I remember the push rod tubes being a source of an oil leak.

To much oil is worse then not enough. If it's way over full then when the engine is running it will cause the oil to go out of the weakest point and that is the engine gaskets.will Cause oil leaks.
Yes, if it leaks oil through and on to the spark plugs, it will foul them and cause a missfire.
