As a few of you may know I have been rebuilding the Willy 3 engine these last few months.
The engine went in and the 1st fire up went well. After switching off to cool down in prep to re torque the head, there was a pool of oil under the car. It appeared to have come from the cambelt side. On closer inspection it was decided that the crank shaft oil seal had failed. So off to Renault for the genuine part and it was fitted pretty soon after. The failed seal on rebuild was part of a gasket set and was pretty poor in comparison to the genuine seal so I was very confident that that was the problem. Anyway......Just fired up the car again and all was well with the running, oil pressure at 5bar on cold 3bar warm on tick over, but oil was dripping off the plastic cambelt casing again. So its all in bits again but I cannot see where the fook its coming from. The camshafts are dry and I cannot see anything obvious. The oil is travelling around the aux belt and alternator and around the inside of the cambelt cover and of course on the cambelt.
I have removed the cambelt casing and intend to start the car up once the bottom pully is back on and watch for oil spraying out from hopefully an obvious place.
I wanted to share this flustration with you guys but also ask if anyone has any ideas on where it could be coming from? If nothing is visable the next stage will be removing all pulleys and the cambelt casing back.
Any help or pointers will be appreciated.
