<VV> Parking brake thanks, exhaust tube question

[Jim McLott]

FIRST:   Find yourself a big wooden dowel that's a snug fit in the 
tube and about a foot or so long, drive it home...   the dowel will 
allow you to rock the tube back and forth a tad to loosen it, 
whereupon the vise grips clamped onto the tube will grip it tight 
without crushing it and allow you to yank it out of the head.    It 
also gives a large screwdriver something to pry against so as to help 
convince the tube to come out.

An appropriate sized socket can also be used in place of the dowel.  And
a squirt of PB Blaster where the tube is inserted into the head won't
hurt, either.  Worked for me.

Drive the replacement tube in with a hammer and a block of wood. 
Make sure the depression on the side in in the correct direction.

Coat the inside of the hole in the head with a thin coat of anti-seize.
Then get some Freon spray used to temporarily cool electronic
components, available at Radio Shack.  Spray the end of the tube until
the tube is so cold it's painful to hold.  It should then tap into place
easily.  Again, worked for me.

After you've put new o-rings on the pushrod tube and finished installing
everything but the valve cover, you'll need to adjust the valve.  When
you get to that point, we'll be happy to give advice on how best to do
that.  Just ask us!
