Wierd noise from my valver???

[dalla]

Hi guys

Today i was driving in my valver. I was in second gear, and wasn't driving very fast (around 30 km/h). The as i pressed the clutch, there was this big klonk. Now it sounds like the engine is lying on the subframe. There is also quite a lot of vibration in the car. Other than that it runs fine. I've checked the engine mounts, but couldn't see any breakage.
Have any of you tried anything similar? What could it be?
And what engine mounts is most likely to break.

check the one under the battery tray, other than that bog bone mount

If the gearbox lying on the subframe?
