[V8] Rebuilding options

[pashamad at aol.com]

Yes, Sean, I'm still there keeping an eye on all of the arguments about rebuild options.
As you know, I've successfully rebuilt two PT and ABH (now yours) practically with TotalSeal
rings and stainless steel mesh under the valley cover - Steve B. is absolutely right:

My theory as to why a rebuilt motor resolves the problem is that the tighter
rings/valve seals reduce the amount of blow by gasses, which leads to less
oil vapor to build up in the recovery system.  I have a pad of brass wool
which I was planning to drop into the recovery system on the PT I have
sitting in the garage (that engine that came from #2).

And I have originally led foot (head?) too!
Now I'm trying to make S8 to consume some oil (unsuccessfully - for now!).
If anyone interested in torque specs and drawings for ARP rod bolts - I can send as attachment 
in PDF.

Ladies and Gentlemen
Here is the deal Audi used CHEAP rings in the V8 engines.  Here is one of
he main issues with Alumisil blocks.  Silicon bores are abrasive, think
bout it silicon is tougher then iron and wears stuff out.  The stock rings
o the best of my knowledge are plasma coated Iron rings (CHEAP) the plasma
oating is required to prevent premature wear.  What happens in abused and
igh mileage engines is this coating wears 
and you start getting excessive
ing wear.  The only solution to this is new rings.  My suggestion is
hromoly rings with a low friction coating if you would like.
Here is a picture of my 4.2L ABH code engine as the PO rebuild it.  (if your
eading this Pasha thank you for the fine work ;-) )

The rings are available and out there.  Heads are also a known issue on the
ewer and older VAG motors.  I plan to rebuild a 4.2L ABZ code engine with
ew rings, new guides, new seals, etc.  The smoking issues is a know issue
nd is not limited to Audi engines.  There are other alumisil engines that
ave the same problem.  Also honing this is an option find any one that does
44/968/928 Porsche stuff same exact technology (trust me BTDT) most should
e able to help you out.
As for torque specs I can't help you there at the moment, but I'd guess use
hatever a 2.7tt uses for the rod bolts, the mains I can't help.
