More likely simply seized because of inadequate flow caused by coke.

Not what the owner's manual says.

Yes, because the manifolds have to come off and at 140,000 miles the studs
will very likely shear. Expect a 'head off and drill out studs' item on the
Committee Member, UK Audi [ur-]quattro Owners Club
ps:Ditto to what Phil said about the studs- The other pricey item is the
exhaust manifold which I opted to replace When I was advised it is "most
always cracked"by the service manager. Price on this item was $1200 and I
bought it for several hundred from another source- only top find my bill
had moved up by the same amount. Total cost for valve job $3k. btw sorry
for the ambiguous meaning of
"being cracked "..by the service manager. Mike Posner
