Welcome to the club, Brian. BTDT 3 times already. The manifold should be
checked for warpage and trued on a mill next time you have it out.

No, but I believe it is available as a spare part from Audi as a
supersession for the crappy OEM mfld.

Ivor sells one (actually it's a header -- five individual *snakes*), and so
does Ned. Both are said to drop the turbo kick-in point down low on the
tach. I rode in both cars, that was FUN!

It's not really neccesary. I easily do it with the head in place, just pull
the intake mfld and the air box out. No need to drain the coolant either.

It's like re-using a condom: save a coupla bux and then worry for 9 months
in a row, have I gotten away with it??? =8)

I would. So easy to do, just take the cam off.

Alas, no, only the head bolts.

Yes, some of the listers did. Mike Z, care to comment?
