Add a little flavor to the broken CV Joint on the front driveshaft I've been working on getting resolved. Driving on the highway the other day, went to pass and give it some gas ... got some odd hesitation on from the trans (holding 10th ... not really wanting to kick down). Pushed a little harder, and got a "low oil pressure" warning on the dash - along w/ some odd turbo boost pressure readings (fluctuating mid-high range). Pulled off immediately, shut her down, checked the oil level and looked for a telltale blood trail. Nothing seemed off ... restarted and the pressure was in the green, no CEL or continued pressure warnings. Headed right home. Similar event - stopped again - all looked normal. Trying to merge back on, got a stutter and a CEL. Code reader showed misfire on cyl. 6. Also showed oil pressure was mid-40s at part throttle on live data. Just got to the mechanic and they found the driver's side valve cover cracked (laterally) across the entire width. Best they can surmise is that's causing a vacuum leak, which would cause the trans/motor to go into a "protect" mode, which is causing the trans to limit hard downshifts. The coil pack on 6 was bad, so that's the misfire. The oil pressure sender/sensor likely bad too... no pressure warnings on live data or since. So new valve cover/gasket and new coil pack to get me going again... oil pressure sender/sensor is back-ordered from Ford, so gotta white-knuckle it and see if the problem crops up again while cruising. Fahhk - man. Never heard of a valve cover cracking under normal useage - and at 69k miles. Had to drive down there and see it to believe it. Anyone dealt w/ this?
