Break down, engine split oil,

Today my 900 B201 H split oil. The engine compartiment is splited with oil. I could checked the distributor and the oil hatch and the link doesnt come from that places. I also checked the cooled deposit and is free of oil, the car doesnt loose power so I think that the engine cam joint is fine. What do you think could be...
Also last week I feel a sound in idle like the timming chain sound..., but as I said, no loos power. When should I change the timming chain?
Last week in the garage they change the engine mounts, could be something related?

Finally I also could record 2 videos.
