I am losing oil (crankcase, 5/30 w.) At the rate of 1 qt. Per week. It is not using oil but is spraying underneath the car but only on the right side(passenger side) but only while driving. When it is parked there is no leakage. I have checked the most common reasons (valve cover gaskets, oil pan, oil pan drain plug, cam and crankshaft seals) It is like a high pressure oil line has failed while driving (engine pressure--?) And when I stop and check underneath, it is dripping motor oil. I clean it off and the same thing happens next time it is driven. There has got to be a way to pinpoint this perplexing problem but I do not have the expertise to solve this mystery. It has a 3.8 L. Engine and an automatic transmission.
