Why is the oil sump/pan so wide? Looks like an automatic trans pan.cbulen said:Here is a photo of my own ABZ (same V8 that Paul is using).
The red lines show where the jackshaft pretty much needs to run along side of the engine. As you can see, there is some stuff in the way. One thing not shown is the starter, right where the red lines meet the rear of the block (where the ring gear would be). STarter was removed from this engine, but it is also in the way.
There is also that PESKY right side CV joint. It takes up a lot of room.

I'm not an Audi engine designer, so I can only guess.
Audi never intended for the ABZ to be mounted transverse. They also wanted to maximize oil capacity. The ABZ holds about 2 gallons!!! of oil.
They went wide instead of deep then for the oil sump. Makes sense. Most of he Audis sit pretty low. Good enough. i find that most new larger engines hold more oil than years ago. A standard smallblock Chevy/Ford/Dodge held like 5-5.5 quarts I think. I think new Ford Truck V8 hold like 7 or 8 quarts.
