I was running engine for 3 hours today. I decided to do the test although vibration problem. A friend was telling me: Take a lever and check each mount separately. And i did it.The result was that i could notice nothing suspicious. So i did run the engine. But after 2 hours and 30 min i did insert in gear and went for the ride. I could notice less vibrations when transmission was working. So, definitely there is something wrong.
Here is the video:
