does the tightness of the bottom pulley bolt affect the front oil seal?

i ask as since undoing the bolt then bolting up a 36-1 teeth trigger wheel there is now oil dripping from this area?

 

Must just be coincidence mate, the crank has a step in it which the bottom cam belt pulley rests against, so it shouldnt affect it.



the only thing i can think of is if you've had something in there levering the bottom cam pulley off and damaged the seal?

 

i never touched the pulley itself,just removed the bolt and put the trigger wheel on and boleted it back up?
going to take it appart tomorrow and have me a look mate

 

Its probably got the original seal in there anyway

Think yourself lucky its not the one the flywheel side
