Engine is out of the car for a transmission "refresh" :-) --- thought I would post pictures of some of the "While You Are There" type work.
Meanwhile I have the frunk carpet at home and will be sewing a new binding to the carpet to make it more of an "RS carpet" --- never thought I would have gone to Jo-Ann Fabrics for parts for the Porsche! (Vinyl fabric to make the binding) .... I will have to learn how to sew....

Reason: added breather area picture
In your last photo, right corner of the tray, there appears to be a round seal, and within that seal, is the varioram rubber air manifold, which becomes collapsed over time.
The DIY fix is to push (5/16" spring, I think) into the collapsed area for support and flow free air passage; buying a new one will eventually collapse, whereas the spring won't.

Don't forget the age related hydraulic adjuster cartridges, by 60 or 70K you may be back visiting the valve covers if you leave them out of your planning. I replaced the mat on my car at 80K and 10K later the edge of the OE replacement mat began to crack. I would look into one of those non foam rubber mats that will probably have a longer life and are not as thick allowing for better access when servicing the intake or the idle valve. I bet adding a foil mat between the rear cabin window deck cover and the body in conjunction with a thin mat in the engine compartment would be just as effective as the OEM solution.

Thanks. The lifters I have considered but not done anything about - they are currently very quiet. I wonder - is this a purely age related item?
Regarding the mat -- I am using Appbiz's "ultimate: pad and crossing fingers that it will not disintegrate as quickly as the OE pad --- I found the information below from Pelican somewhere I think -

I would argue this. These are not paper gaskets, which one of your links actually refer to. 574 is fine for those, but a silicone I-ring grease or Curil T are more appropriate in my belief for a thick seal used on 993 covers. 574 is pretty old technology, and not the best sealant for many applications.

Ah, I see. No doubt I am not well educated on this.
Have your views on Loctite 574 changed since a few years ago? Very likely technology has changed since then and I have been blissfully unaware ....
A thin coat of Loctite 574 worked fine for me. I pretty much went by Henry Schmidt's (Supertec) list of sealants that is used on his 911 motors. He builds some pretty nice little jewels. This is his list, if you haven't seen it:
Outer case halves perimeter : Threebond 1104
Bearing web surfaces: Loctite 574
#8 Bearing O-Ring: Threebond 1211
Case Thru Bolts: Dow Corning 55 on Green Viton O-Rings
Flywheel Seal: dry
Front pulley Seal: dry
Intermediate Shaft Cover to Case: o-ring Dow 55, gasket style 574
Oil Breather Cover to Case: Loctite 574
Cylinders to Case: Curil T
Cam Towers to Cylinder Heads: Threebond 1104 Cam Chain Housings to Case: gaskets Loctite 574
Cam Chain Housings to Cam Towers: gasket Loctite 574
Cam Chain Housing Cover to Cam Chain Housing: Gasket Loctite574
Gaskets: Thin coat of Loctite 574
The Loctite Hysol is a perfect epoxy for sealing galley plugs and tensioner pins.
On late 3.0 & 3.2 cases it also seals the exposed oil tranfer tube in front of the cooler.
If you can't find 1104 use 1194 and Dow 55 can be replaced with 111

Those places were either paper gaskets or metal to metal seals, and a 3.2L engine.
Apples to oranges when talking about the chain cover seals on a 993.
These seals we are talking about are more "3 dimensional" and one side of the seal is almost pointed. The seal is what is doing the work, and a Curil T or something like Dow 55 would make more sense. I'm not saying you will have leaks, but I don't think 574 is the right stuff.
Got it thanks. The part that wasnt clear to me was that that old thread was about changing gaskets on the chain cover for 993s. And, in that 993 thread, there was a lift of information from an even older thread about 911s.
