Why do you jack up the rear with the jack forward of the sump cover (for the older 911s that have a cover)? That puts a bending load on the engine/transmission assembly. I'm pretty sure the assembly can withstand this load, but why? If I want both rear wheels up, but don't need the fronts up, I jack from the rear of the assembly, just forward of the motor mount. Or from the rear motor mount. This means the load path goes up to the chassis through a minimum lengthwise distance, and minimizes it. Besides, it is quicker and easier to locate the jack.

I don't bother with a hockey puck, being willing to accept the odd scrapes and gouges, but nothing wrong with a puck as long as you are extra careful about fore/aft movement until you get the jack stands in place.

Though none of my 911s have had the oil line from the scavenge side run across the back, the way the stock system had it from somewhere in the 2.7 era.

When I've replaced broken exhaust rockers or springs at the track, I've jacked the side involved way way up, jack stands fore and aft, and gotten to work on the affected side. A rag on the exhaust header deals with the few oil drops. I've done the same when checking lash, since the engine is dead cold and oil has had some time to accumulate, and there are those pockets which are a bit below the return tubes. But sounds like one can get away with less mess. The Rothsport one way valve ought to prevent the oil level in the sump from rising above the return tubes.

Lifting the whole side (jack stands up front under the front of the A arms) keeps the oil from pooling forward in the cam carrier spaces.
