I will do that...
The tube I refer to i the one letting oil back in and it's placed a little bit further to the rear and a bit higher.
I added a picture to show. You see it on the arrows.
I suspect a dry hose since it seems strange that a hard fitting can start leaking all of a sudden. But it be because I removed the intake and exhaust manifolds to change gaskets, and had to remove the oil filter. The tube or fitting might have gotten a bend that made something break. Will check on saturday. Thanks
