I have a 2007 RX350 with a serious oil leak. I have read and replaced the VVTi cooling line and still leaking. Notice after looking while engine running that the oil appears to be coming from the top of the oil pan lip on the engine not through the gasket. Can not imagine that this much oil could be working through the pan screw. Your thoughts. I guess I will remove the oil pan and hope this is the case, not a crack in the block.
