oil leak

Pete has given you the best advice on that cam plug. Better to seal it that to try and replace it. Since you have confirmed the cam plug, there is no need to replace the rear main seal of the rear main carrier gasket. Good luck.
 
I've done as John Zibell suggested and taken the engine and gearbox to my dealers to replace the gasket and seals.

As a precaution while the bikes striped I've had the rear crank seal, flange gasket, gearbox input seal and a new clutch fitted. (As the old one is over half worn)

The problem now is the cam end Welch plug which was leaking. We have a new plug but we are unsure how to fit it. My dealer is new to Guzzi and this is their first Breva engine they've worked on. They've contacted Guzzi and are waiting a reply. If anybody can give us some advice or tips it would be much appreciated. What tool is used?? to "bash the plug".

Take a look at Pete's post above. If the plug hasn't been removed, it is best to just clean the area then seal the old plug with epoxy. If you have removed the old plug, then you are in for a devil of a time as Pete said.
 
I got the engine and gearbox back from the dealers with a new crank seal, flange gasket and gearbox input shaft seal fitted. I've left the old welch plug in place as pete roper recomended and covered it with "JB Weld", an epoxy filler. If it works or not its not realy a problem as the leak was so small and knowing what I know now I would have left well alone, still its better to be safe than sorry. I also put a new clutch in while I'd got the bike apart, the old one was about half worn, I think not bad for 35000 miles.

It took me a day and a half to put it all back to gether on my own. I borrowed a engine hoist which I hung the frame from and lowered it onto the engine, much easyer than when we took it apart without one. I must say the whole job was quite straight forward and I would have no hesitation in doing it again. In fact I throughly enjoyed it, I must get myself a project bike.

One tool I did have to go out and buy during the job was a 14mm Hex key socket for the swingarm spindle.

I've done about 700 miles since the rebuild and all's well.

I thank you all for your help and advice, ride hard and be safe,

Bronco.
