Case sealing suggestions : This is how we build all of our engines.
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

From memory that location on my case is a through bolt and nut rather than a stud.

Stud 35 in your previous diagram is at the pulley end of the case. The above pic is at the crankend of the case.
I will have a look when I get home and measure the PL for you, as I did't need to pull that stud when I sent my case to ollies.

All engines need some for of clearance, this is where the very thin layer of oil forms to provide lubrication. Without clearance you either get no oil or the thing wont rotate.

Good eyeballs. I agree... there are some HUGE gaps between the rod and the rod caps. Unless its another optical contusion, something is wrong there. The caps should be tight to the rods. The bearings provide the clearance for proper oiling.

From reading Wayne's rebuild book, in general, the acceptable clearance is between .03mm to .08mm with most coming in at around .05. Of course this is for model years up to 89. Does anyone know if this spec is the same for 964/993?

You guys had me scared for a second. The rod bolts are indeed torqued down. It is an illusion. What you are seeing is the squeezed out ARP lube (black).
