If the engine mounts are really bad, the engine is pretty easy to shake by hand. The driver side mount on my E36 was completely shot, I could put my mitt on the bracket and rock the entire engine up and down. The hydraulic fluid was everywhere. This was discovered shortly after buying the car, a few days after the fan contacted the shroud and exploded everywhere, destroying the radiator, etc.

If your car has a clutch fan, check engine mounts once in a while, so the fan isn't moving around breaking everything. I would never get rid of the clutch fan.

I did the OE mounts by corteco on the X5 and the E36. Lifetime replacement. I'm not sure in what part of the world they are made. But I'm sure they will outlast the oil pan gasket and the front differential o-rings. It's more of a while you're in there for the oil pan I think.
