Hi guys.

Just the other day, I noticed i'm getting puffs of blue smoke from the exhaust. It only happens when I give the engine a nudge, like just before I pull away in first, or between shifts when I let the RPM rise too quickly. I know a bit about bore wear and suchlike, but the thing that has me puzzled is happening under the bonnet. There seems to be an oil leak, coming somewhere from the TOP of the head. It starts at the joint between the head and the valve cover. It is definately active, there's a fair amount of wet oil on the front side of the head, near the sparkies, and also on the right side (from the front). Is this unusual, or a common occurance?

It just seems like an odd place for a leak to be happening.

Cheers,
Fergus
