To again use a legal maxim, "non sequitur"..........

Speaking of misquoting, I never said or implied anything of the sort.

Seriously, seeing two of the most knowledgeable and respected people on the forum at odds is like watching King Kong versus Godzilla. And I'm out of popcorn!

Thanks for the vote of confidence but Jeff is hands down one of, if not the most knowledgeable person on here, and 100 times more knowledgeable than I, especially when it comes to porsches and have a great deal of respect for him. There are, however, times when dealing with laymn like myself and others a little more clarification would help. Not just "get the right part" or "your updated replacement engine is exactly the same as your original engine" and, in this particular case, saying I was wrong for telling you not to use assembly Lube on the flywheel and pressure plate bolt threads.

In the end, we both agreed that you shouldn't use assembly lube on threads where loctite is required, and that's the important takeaway.

Another change in plans. Bank 1's cam chain pads are installed, the cams are back in place, and the cam cover has been bolted on. The engine's ready for transport. I had intended to finish the engine — install bank 2's pads and replace some miscellaneous stuff — before I made the move to my new place. However, the house I've been renting is on the market and the sellers are leaning on me to move out ASAP. This project is difficult enough without people breathing down my neck. I could play hardball and tell them to pound sand until July 9, the move-out date in the notice they sent me a month ago. That would be pointless. From U-Haul, I'm going to rent an auto-hauler trailer for the 986 and a large covered trailer for the new engine (plus my tools and other possessions). The engine will travel strapped to a 4x4 pallet with 4" wheels (which make it relatively easy to move around on level surfaces). Once I get settled at my new digs I shall resume this project, free of pressure from external forces. In the meantime I'll be checking in here.

Just a note about the oil scavenge pump... I don't understand why so many how-to articles and videos insist that preserving the pump's orientation using a marker is a must, when the pump's orientation is cast into the face — 1-3 for bank 1, 4-6 for bank 2. As long as the cast numbers on the left side (inside) correspond to that bank's cylinder numbers, it's impossible to make a mistake and mount it upside down. Here's a photo from Pelican's technical article, although the article makes no mention of the cast numbers (which are hard to see in the photo):

Good observation, except on bank 2 the 4-6 stamp would still be on the right, but inside, correct? If that's the case, then both sides are mounted in the same orientation? Yes, the numbers would make a good reference.

But the instructions should be better than "install the same way you took it out" in the event someone was in there before you and reinstalled it upside-down. For example, does the indented rectangle in the inner circle of the outside cover point up on both? If so, that could be another reference. Or, perhaps more importantly given they evidently come apart, the notch on the INSIDE part that meets the cam (shown in smaller picture facing the installer's thumb) would be the best reference.

There's a thread on this:

Post #4 by RodJ shows a diagram with 1-3 stamp on the inside (towards crank) and the arrows pointing down for bank 1, and the next post says 4-6 towards the crankshaft for bank 2. (so they are actually both oriented the same way)

Not sure why the Pelican article didn't mention the stamp numbers or arrows. Seems to me it would be simplest to say "the arrows are supposed to point down on both banks"

Bank 2's pump is installed upside down in relation to bank 1's, so the number placement is reversed, 4-6 on the left, toward the crankshaft. Note that the rectangular indentation next to the center of the casting is on the top for bank 1, the bottom for bank 2:
