Trashed CGT Engine

[Don Muirhead <dmr@kwic.com>]

Rebuilding '86 CGT with trashed engine - car has been in unheated storage 
since '90

Yesterday started stripping down the coupe, so we sprayed every bolt and 
nut in sight with penetrating fluid.  While waiting for this stuff to do 
its thing (we actually wanted to start on the suspension), curiosity got 
the better of us so 10 hours later this is very briefly what we discovered.

Broken Cam (not Audi - only markings #03783-88).
Extensive damage to lifters (still can't account for all the keepers), 5 
broken valve springs, 8 broken valves balance showed extensive wear.
Cracked head (actually split).
#3 & #5 cylinders cracked, 3 blown pistons/rods (2 pistons showed 
considerable wear/broken rods).
Broken crank (#3 cylinder) elongated break - severe pitting and 
discoloration (yellowish/brown) at the break point (defective?).

I've never seen a usually tough little engine go down this way, and neither 
had the fellow (Audi mechanic 15yrs' ) who now owns this stuff, so we have 
a couple of questions to those who perhaps have.

1. Can anybody identify the Cam - performance Cam no markings just 
#03783-88 on the shaft.
2. Has anybody ever had an Audi crank break (elongated) and found pitting 
and discoloration at the break point.

Thanks
