So it is and only lost a little more than 2 liters and nothing showing on the dip stick which scared the .... out of me. Checked engine and traced the oil leakage back to the top of the engine. Removed plastic coil cover on top engine and noticed oil pooling 1/2 way along the length of the upper cylinder head looking at it from the passenger/exhaust side. This oil made its way leaking down backside of engine,trans.,and exhaust making it appear like a major loss of fluid. Cleaned the oil and ckecked the spark plug wells of number 5 & 6 which were empty and clean. Topped up oil and restarted engine and observed oil ozzing from an upper cylinder head center bolt,the one beside the 5th coil. What are the possibilities? Hairline crack, gasket,warpped uppercylinder head. Has anyone seen anything like this. Is it a cause of what you all call pourous blocks.
Thanks for your time Dieter.
