Considering I do all heads thru my shop this way (with routine attention paid
to cleanliness of all open fuel lines/ports - that's not unique any specific
car), never had a problem.  In this instance your *opinion* of poor technique
saves a LOT of time and carries little risk in practice.  Breaking bolts in
heads carries more risk.   That air fan bracket above the CPR is the first of
the most common.

Cutting corners isn't necessary, but neither is removing IM/EM's and CPR,
turbo, FI's, air fan bracket or airbox.  A LOT of work is not prioritizing
old audis repairs in terms of "in car" removal vs risk of drill and retap.
What's with the driveshaft shield?

Whatever.  That really isn't a concern is it? At least I never thought so.

Nope, and it can be done solo, btdt all the time.

Phil, some would consider peer "review" of procedures as something to be
thankful for (damn man, you do it *all* the time, goes around comes...), and
the purpose of these lists.  Your procedure really makes this R&R more
complicated than necessary.  I can easily envision *your* method as a
"working" one Phil, not the point.  I just wouldn't recommend it, nor at all
propose it's the best way to skin the cat.  I look at the procedure you
posted, and find many things that indicate that you have a 'set' way of doing
things.  Proposing it's "Best" or carries less risk (opinion), comes from a
mindset of not trying to do a routine procedure better.   Put the priority on
age and it's affects, not standard rules of fuel system cleanliness would be
my first advice.

My "methods" aren't mine alone, they are a culmination of many others' btdt
over the years.  Looking at your documented procedure, the question "Why"
comes up too many times.  I can certainly can see the end result being the
same, if that's what you want to hear.

Let's face it, the older the cars get, the more we need better ways.
