It sure is light years easier to drill the studs out on the bench, but since
it is principally DOable on the car it is still a lot faster.
And cheaper too:
1. You don't need a new head gasket set
1a. Don't need a new valve cover gasket
1b. Dont need new head bolts(very expensive! and you DO have to replace
them, they stretch)
2. you don't need to drain the water
3. No need to replace oil and filter afterwards (since you will not open up
3a. No need to retime the engine.
4. No need to disconnect all that assorted stuff (accel and cruise cable,
hoses, jacks and plugs, no need to remove injectors or fuel lines etc. etc.
Most importantly, "if it's not broke, don't fix it". I heard that Audi uses
some unique assembly tech @ the plant, it has something to do with a dynamic
balancing of the entire engine as the assy, I forget exactly. In short,
people who routinely rebuild those engines say that once you had the head
off the engine is not likely to rich that astounding mileage Audis are known
I have done the head job once (blew the gasket) and did just the mfld 3
times - my vote is: do it on the car.
Unless you have some problems with the head also, then do the head and all
