The semi-deep sumps do seem quite a good compromise.
And yes Ruairidh, I've only ever tried dropping my engine in 'avec gearbox'.
On leaks, I think mine (from the sump) are mostly due to inaccurately drilled fixing holes, which I mean to address later but haven't got around to yet. I have noticed that driving style affects the rate of oil loss considerably. A fast run from Bedford up to Newcastle on the A1 (with a lengthy detour into Co. Durham) darn near emptied my deep sump and nearly caused the wetting of pants when I checked it. This prompted me to invest a lot of money in a gallon of 20w/50 to keep me going through my touring holiday, but 3000 miles of quiet country roads later I still hadn't opened it.
Yes Bob - I'm running a 3 bearing engine and like to think the extra stiffness is a good thing.
I'd hazard that water retention is a factor in the early demise of A7 rear roller mains. Acid attack > rust > wear.
Running at the wrong oil temperature affects the viscosity / flow of the oil, on which robust lubrication depends. I've also read that 'cold' oil may account for 3 or 4% reduction in engine efficiency.
