The operation was a success but the patient died :-(

28/10-2007

A new oil pump and new bearings were fitted and everything was put back together again. Unfortunately the new pump couldn't master more the one third of the desired pressure. We hoped to the end that it was the old pressure gage that was failing but a check with an external gage showed the same result.
This means the engine have to go to an engine shop capable of giving it a total overhaul. Only good thing is that it isn't driving season.

As a site note you'll find more info on engine oil pressure here
