Default New engine, smoking car only at the track

I'm posting for a friend:

My friend has a WRX that he had built to an equivalent STi engine by a well respected shop locally. After going back an forth with the shop for incomplete work (poorly fitted i/c, unbolted exhaust bracket (which made the ECU think the engine was knocking), oil leaky turbo even though it's new, etc) the problem were finally sorted out and it was protuned and everything. Supposedly good to go. He did a proper 1500 mile break in (the tuning shop had a rev limited map during the break in on).

The car works fine on the street and spirited driving.

But at the track (particularly when driving hard), his engine bay had a little bit of smoke like oil was spilling on the hot engine block and was burning off. Also, his exhaust was smoking blueish a bit. His EGT's got up to 1600 and he backed off.

He popped the hood in the paddock and sure enough, small amounts of oil was "steaming off various parts underneath the intercooler. But there was also bluish and greyish smoke coming out of the tail pipe, even at idle.

The next session, he toned it down and under 5200 rpms. The smoke from the tail completely went away. But get on it again, and the smoke would come back, and eventually "go away" if he toned it down.

So it seems that under stress of very high rpms and load, the car developed some kind of leak that would burn away when the car is run under less stressful conditions for awhile.

He's going to ask the shop, but with so many problems experienced before, he's looking for other opinions too. Any ideas of where to look or what can be the problem?
