Some OEM motor mounts like for BMW's have oil in them to reduce (NVH) noise, vibration,harshness. They are not serviceable, if they leak.. they should need replacing.
To change Volvo oil filled 940 engine mount, push a container under the oil drain plug. Unscrew drain unplug and remove the cap from the oil filler hole at the top of the engine. Unscrew oil filter to drain. Then change oil.
Not to my knowledge.
It is on the driver side of the engine block ,in front of the engine mount. It is on the driver side of the engine block ,in front of the engine mount.
If you have over filled your engine oil, it will not "leak" unless you have completely filled the engine with oil and is pouring out where you put it in. However overfilling even as much as little as 1 quart can lead to catostophic engine damage as the crankshaft will spin into the oil in the pan causing it to foam and cause oil circulation problems throughout the engine leading to overheating and engine siezing.
You probably spilled some oil on or near the engine, making it burn when the engine heats up.
Drain it out and put the correct amount in
Oil leaks can be hard to find. Wash the engine good. Keep the oil filled, and look daily for signs of oil, even underneath the engine to see where the leak is.
Remove the drain plug under the engine and remove oil until it is at the proper level. Running the engine with too much oil can cause damage.

It is on the radiator side of the engine, above the oil pan, behind the engine mount bracket.
