My question is, how long does it take to melt a forged piston at 25 psi lean?
I know it depends on how lean, how much timing advance, ambient temperature and
a half dozen other things, but if you get on it, it slips past 15 psi and flies
up to ~23 psi and you let off right away, is the chance o

Marc,
The combination of the smoke, oil consumption, and the oil blowing
into the airbox does not sound good...especially when you speak of boost
being "pegged" on the 20 lb gauge.
I had a similar symptom on a 90 TI Daytona, which ended up being a
piston with the upper ring land melted off...no

Perhaps its sucking oil past the valve guides/seals?
A leakdown test could help confirm this by filling the chamber with air and
using a stethoscope to listen for wh

What's the point of a forged piston then? They wear out way faster, you
say they can't take abuse.. What's the point???

Yeah, but if a piston is melted, then wouldn't I have a bunch of blow by
shooting out of the oil filler cap, pu

Why do you say that?

You can frag a forged piston real quick if you are boosting out of tune
enough.

I'd run a vacuum line straight from the manifold to the wastegate can
until you figure out the problem with boost control. 25psi on a 2bar
map is BAD. Did you put forged pistons in there? The way your boost is
rocketing even under low throttle, it sounds like you've blown a line
off somewhere in th
The really odd thing with the smoke problem is that it just started last
week - 1700 miles on the new engine. So it's not like the vacuum lines were
put back on wrong, etc, it just suddenly started. It doesn't smell like oil
smoke, but I have to assume it is, since the oil consumption is quite high
