Well, I'm definately not going to try and track one down, I'll leave my w@nker of a landlord with the oil stains to sort out

 

its more about the land for your children and there childrens children ect ect

its also why some garages aint yet turned into flats,,,, they got soo much crap and oil over the years in the ground that they cant build on without digging everything up and starting again proper ( which is good for me as one of them places is the garage thats doing the bodywork on my car and lets me use hes ramps pmsl )

there is some aerodynamics in the design though ill admit,,, but its to STOP it ripping off at speed rather than a air defuser

 

If it's just to stop oil dripping on the driveway then it's a **** poor design as it's full of holes, especially large under the sump and plug. Mine always marks it's spot

Any ideas what the gearbox cover is for then??????
