[Vwdiesel] Quantum problems"head removal"

[Erik Lane]

Unless, of course, the book calls for there to be lube on the bolts
and tells you the numbers to use with lubed bolts, which it sounds
like this one did. All of the Bentleys that I have looked at called
for lubed head bolts. (Though that's not more than 5-6 manuals that
I've dealt with - I've been pretty content to stick with early to mid
eighties cars.)

As far as the question about using torque wrenches I've never seen it
said that they could be damaged if you use them to loosen stuff, or in
other words tighten a left-hand thread. In fact the clickers are made
to be able to be reversed and the beam torque wrenches have scales on
*both* sides of the bar to read in both directions. In the clickers if
you look at how they're made I don't see a single reason why it
matters which direction they're used.

The block should be identical. Yes, you would have to change mounts
and oil pan, possibly also oil pump, but that would be good to have
new, anyway. Also change most of the accessory brackets if it came
with any of those. I've used a dasher block in both a vanagon and a
jetta with no issues. They're all pretty much interchangeable. (With
exceptions for turbos.)
