Looking for suggestions, recently changed engine in my 2005 1.3 multijet sx.
After putting everything back together, everything works fine except for the aforementioned problem. Thought leak was coming from the cam driven oil pump, not the case. Now seems to be coming from behind the thermostat, maybee between the head and block? Any suggestions welcome, maybe somebody has experienced this problem before????

Might be better to post a picture, it's quite a crowded area on the 1.3
