Sunset Porsche out in you neck of the woods has them for $156.

I can't seem to find that AOS at Sunset searching for "AOS" and "air oil separator." (I'm not having much luck searching for parts, obviously.) I will go with factory parts whenever possible. Except, for example, when they want $265.48 for an "air tube," and that's with Sunset's $22.59 discount:

Give Luke and the crew at Sunset a call, they will hook you up at reasonable $.

So, AOS and coolant tank. Anything else in the "must replace" category?

The new rear main seal has been installed. Getting the old seal out required some determined reefing on the sheetrock screws, but it finally popped out. The tool used to seat the new seal worked like a charm. All in all, it was an easy job, as others who've done it can attest.

I intended to include these photos in the previous message, but I clicked "Submit" by mistake and editing doesn't allow uploading photos, even under "Go Advanced." Mutter, mutter... And I thought I had taken a shot with the seal completely out, but I thought wrong. Not much to see, just blackness surrounding the crankshaft.

As I said, this was an easy procedure. Wish they all were that easy. Wish replacing the cam chain wear pads would be that easy. That's the next project on the schedule. Actually, it might not be too bad, as long as I: (1) fully understand the procedure, (2) take it slow and careful — there's no hurry, (3) be meticulous, and (4) take lots of photos. (Photos kinda come in handy when putting things back together, I've found.)

Removal of old RMS:



New RMS, ready to be seated:



Tool in place:



New RMS, seated:



Supposedly, the tool actually seats the new seal in a slightly different place, to avoid wear from the old seal. Not surprisingly, I couldn't detect the difference.

You answered my question before I had a chance to ask. So it does seat in a slightly different depth! Very interesting, as the two I have had apart showed a light line where the seal rides, but not deep enough to feel it. Tough stuff!

See the rubber hose connected to the fuel rail? Note the crimp next to its metal sleeve. The hose got munched when they packed the engine for shipping. Haven't priced a replacement yet. I'm afraid to.

To me that looks more like someone twisted the hose during installation. I can't see how packing would cause that, unless they put a banding strap over it.

What's that hose for? Can't you pull one off your other engine?

That's fuel return at the pressure regulator. It should be easy to pull from the old engine.

That is a fuel line, I think the return.
As suggested by piper... use the old one or:
- has the kink really damaged the line?
- if so a shop that deals in hydraulic equipment may be able to fix it for less than the Porsche part.

Good suggestion, Grant. I'd like to straighten it, but I'd worry that the walls of the line were compromised. A hydraulic equipment shop could probably tell me definitively. I will look over the line on the old engine, as Al and 78F350 recommended. And I'll find out how much a new one costs — but I remember pricing the small plastic tube to the regeneration valve I replaced under the bank 2 intake manifold, and it made my hair stand on end. I ended up splicing in a short length of 5/16" rubber fuel line with hose clamps.

That's exactly what they did — it was under one of two wide nylon ratchet straps, strapped tightly around the engine. The hose is the only casualty. All the other hoses, tubes, wiring looms, and connectors look almost new. I really have no complaint. Whoever pulled the engine took exceptional care to disconnect all hoses, etc., making sure they remained intact, rather than simply cutting them for expediency. Had they done that, I probably would have passed on this engine.
