List of fasteners to replace during top-end?
 

I'm sure someone out there has a list or spreadsheet with the specs on the non-porsche specific fasteners that one would replace during a top end overhaul. If not I can start one.

The ones that are particularly nasty on my car would be

Engine Tin
Timing chain Cover
Exhaust
Valve covers (sometimes you get these with the gaskets)
Misc engine accessory

McMaster-Carr part numbers also accepted...

Majority are M6 & M8 yellow cad nut washers, spring washers and nylocs.

You are doing head studs, right??

Subd, I need a set of hardware for my engine tin.

The engine tin hardware is refered to in PET as "combination screw" "locking screw" and "hexagon head bolt". I grabbed one of the more typical fasteners and tried to thread it onto some M6 nuts I had laying around and it was clearly some sort of locking / deformed thread. Anyone know what the deal with these is?

Which engine are you doing? My engine tin used almost exclusively 10mm long M6 x 1.0 HHCS.

3.2 g50

hhcs?

The locking, somewhat ovaled threads are stover nuts.

Sorry: HHCS = Hex Head Cap Screw

My reference to fasteners above was for a 2.7.

But what is it called when its a bolt not nut?

McMaster has "metric self locking..." ie 96755A329

on some of the engine tin I replaced with socket head, easier to get to and looks cleaner IMO, can find a OSH.
