The same day that they did the work on t-belt, They also changed some o-rings for the power steering pump as it was noisy due to some air in the lines, Is it possible that when doing that repair, they do some damage to the back main seal of the engine. I did some research on the internet and apparently for some of these services they need to lift up a little bit the engine or transmission which can cause this problem.
Thank you very much for your time
