AV Engines Revealled!
The latest information I have heard was from a relative doing contract work for Ford Oz. He was part of an engineering team that was evaluating some major changes with the engine configurations, both with the new 6’s and 8's. He wouldn't go into details but he said that the engines would in fact be mounted upside down.
The biggest problem they had was mounting the gearbox to the engine, most of the gearbox had to be rebuilt, much like converting a car from LHD to RHD. They ended up having to cast a new housing for the gearbox and replace most of the mechanism so that the gear lever would point upwards into the cabin instead of down at the road.
Of course, any idiot knows hot air won't fall, so there were extensive modifications to the air intake and piping. This resulted in the engine having to be moved around 32mm rearwards to fit in the new induction unit.
This, in turn, created a shorter drive shaft, however he didn't say how this problem was overcome.
An unexpected benefit from mounting the engine upside down was the shorter dipstick required because of the oil sump being located on top of the engine. This of course means lower production costs.
There were a few problems though, one was the difficulty of draining all the oil from the engine. This was overcome by fitting a removable cap to the top of the head, which is of course on the bottom of the engine. The most serious problem however was that when driving in wet weather, the engine would suck the water into the distributor and also the leads. The problem was alleviated by fitting a plastic cover over the distributor, and also shielding the leads in small plastic pipe.
One of the more interesting problems they encountered was the mounting of the name plate bearing the engine builders signature. On the normal engine this wouldn’t be fitted, but after this configuration was agreed upon it was decided that it would be appropriate to place it on the sump (which is on top of the engine), acknowledging the work that had gone into building this unique driveline.
Does anyone have any other information to back this up?
