an example of today's loudspeaker R&D

Hi guys,

My car engine is having high engine oil lost, around 1 litres for 1500km. When stationary revving can see smoke come out from tailpipe (4-5k rpm). No smoke come out during normal startup every morning. Engine sounds normal. Compression in all cylinders are 155, 150, 155, 150. Leakdown test shows no leakage. Engine sounds normal no tak tak tak sound. Recent dyno shows 160whp (factory rated 204hp). Engine history unknown as i just bought this car.
I suspect maybe the third piston...
