      Waste-gate solenoid or vacuum leak around waste-gate solenoid lines. I had mine fail and if I kept leaning into it, boost would soar. Not good.

        Last I saw these symptoms and the cause reported, it was a split Si boost pipe near to the fmic where oil had pooled. Check your compressor blades.

        ....had another found their smic plastic was cracked.

            I could be remembering/thinking it wrong. Intermittent leaks? I thought if the leak was in boost control side ....oh n/m, I’m wrong
