Just wondering what the holes are for on the front and back of the yb rocker cover? The front one is between the pulleys and the other is on the back edge where the rocker touches the head.

Surely oil will find it's way out of these and was wondering if there are any bungs needed as I didnt get them in my engine rebuild kit.

Cheers

 

just little breather holes
theres not that much oil in top end of engine
dont block them, just leave them open
they're supposed to be like that

 

they don't need bungs, they just vent the dry middle area within the rocker cover where the plug leads go through.

 

Thanks fellas, thought I'd check first

 

As said vent holes to keep area around plug/leads vented so moisture doesn't build there.
