I checked my Mazda gear box in the plus 4, its mated to the Mazda MZR 2.0 litre unit (supersport engine). I put a small spirit level on gear box casting at 90 degrees to the driveline i.e. across the the car.. viewing from under the bonnet it did appear that the box was cranked over about 10 degrees. I intend to investigate further by jacking the car up on the passenger side and measuring how much oil needs to be added when the unit is level.
Incidentally, i wonder how this engine/gearbox unit sits in the MX5 from which it was lifted, was the gearbox installed level thus tilting the engine 10 degrees past the 12 o clock position
