    Oil Leak

    I just got the Busa engine back together and it runs fine, actually feels strong but I've notices an oil leak now.

    I've attached a pic showing where it appears to be coming from.

    Can anyone tell me what this is. It's a small hole just under the LH exhaust outlet. Each outlet has one of these holes but this is the only one that appears to be leaking.
    It's not pissing out it's about a drop every 20 - 30 seconds when it is warm and running.

    Does it have a welsh plug in it?

    Can you see in the holes?

    I'd have to take the exhaust off to look in, I'll see if I can get a pic with my camera on the phone.
    I suppose if I poked a pic in there and into one of the others it would tell me if the others are blocked off or not too.


    I can't see or take a pic without getting the exhaust off but I did poke a piece of wire about 50mm into the hole of the one that's leaking and also the far RH one that is not leaking. Are they some kind of drain hole for the purpose of getting rid of oil that builds up in there somewhere ?
