As subject says, I've had a very small oil leak for a while now... A mechanic who did my RWC for my club plates thought it was a leaking timing cover seal, so since I had a vernier duplex timing gear to fit, I replaced the gaskets and also the front timing cover oil seal.
Long story short, still leaked.

You have three choices, the primary gear cover as suggested, a vented A+ timing gear cover, or the mechanical fuel pump apperture.
Get him to chase the oil leak down as well...some head gaskets will let oil dribble out from the rear corner behind the thermostat...it all ends up down the bottom and looks for all the world like a timing cover leak..
I have the A+ timing cover breather joining in a Y piece from the clutch cover breather into the side of the HIF44... so I guess that should be adequate for ventilation control?
Embarrassingly I had not looked at the corner of the head behind the thermostat, as rightly or wrongly I assumed it was still coming from timing cover area. Guess what? Just had a look at the back and it is coming from the said spot!
The head had a new BK450 head gasket on it a while ago. I have not re-torqued the head since changing it
. Do I re-torque it now, or does the head come of again?
Mick, thanks again for your advice on this forum.... it goes to show that a comment you made in 2008, has helped me in 2015!
