In a last few days I started noticing quite a bit of water condensation on my oil tank cap.

Attached is a picture of how much water was there after only about 15 minutes engine run on the ground ( including full run-up)

Is it possible that the to oil breather tube is somehow blocked or should I look for some other culprit ?

Thats common after a ground run. Go fly it at cruise power for 30 minutes to get the oil temp up over the boiling point of water and it will be vented out as steam.
