: I've done a couple of these recently
: (and
: another waiting ). Both were stubborn
: due to a number of stuck studs mostly
: on the manifold side.
: For success you MUST get the studs out,
: one by one. Trying to pull or force
: the head off, even with just a few
: remaining studs, is very
: difficult/impossible in my experience.
: Locking two nuts together should get
: most of them.
: Penetrating oil down the sides (proper
: stuff, NOT WD40!), wiggling the studs
: to help the penetration, will help.
: Time and patience also help. I also
: found belting the top of the stud with
: a big hammer while trying to undo it
: shifted a couple.
:
: For the really stubborn ones I welded
: nuts on the top and kept repeating the
: procedures above. On one I got down to
: the last stud and snapped it off flush.
: Managed to rotate the whole head and
: unscrew the stud that way - not a trick
: you can use with the engine in the car!
:
: Most stubborn ones are due to rust but
: I did get one or two with hard-cooked
: carbon deposits.
:
: Patience..... and good luck!

: Methinks the C4 idea is starting to
: look
: better and better:
:
: 1) Arrange for a safe place, clean up
: the surrounding area.
: 2) Start posting like mad, announcing
: when the live event will take place
: (building the Buzz).
: 3) Get some good quality video
: equipment to record things, including
: slow motion.
: 4) Make sure everything is safe (think
: Myth Busters). Webcast the event.
: 5) Post the results on YouTube, etc.
: 6) Use the money earned by millions of
: hits, to finance the purchase of the
: best rebuilt motor you can find.
:
: (it could work)

: Sorry, Scott and Jim, the compressed
: air idea won't work. As soonas there
: is the tiniest crack in the seal, there
: will be a big hiss and the pressure
: will be lost.
:
: No, I haven't tried that idea, but I
: DID try the oil-in-the-bore one. Put
: the plug back in, hit the starter.
: WHAM! A small ooze of oil out from the
: side of the gasket, and
: surprise-surprise a bent conrod.
:
: The cord in the bore methods does work,
: but don't use the starter! Use a long
: bar on a socket on the crank pulley
: bolt.
:
: Going back to earlier posts, weld a nut
: onto the stud - the heat may help, so
: really get it hot'n'glowing. Then
: when it's cooled, wiggle the fabricated
: bolt, to and fro. Try it daily between
: application so your favourite releasing
: agent. Patience will win!

: You know, Scott - that's not a bad
: idea.
: If we gut an old set of spark plugs and
: then silicon in some schrader valves
: (say, for a motorcycle wheel, or any
: other design that positively won't blow
: out (and kill us) under 100+ psi), ...
: viola! The just blip in some air from
: the old compressor. You're right - the
: total pressure applied could easily
: exceed the weight of the block. Once
: the "lock" is broken, if
: necessary, we can resort to the
: "lower the engine" technique
: to tippy-tap it the rest of the way off
: the studs. Nice.
:
: Still doesn't beat lifting the whole
: friggin' car off the ground though!
: That takes the cake. However, I do
: want the video of the C4 removal
: technique in action.
:
: Good idea on the air pressure - I have
: to remember that one for the next time.

: Ciao - Jim

: 100 psi will be 540 lbs of force per
: cylinder - much better than talking!

: SO is this head off yet? Don't make
: me come out there !!!
:
: WE are all assuming YOU have the right
: tools and have used tricks like Muratic
: acid down the studs or if lifted from
: the deck heating the studs with a torch
: and touching with a candle (wax is get
: into the threads)
:
: REALLY need an update as to how you are
: proceeding. Are you removing the
: studs, prying up (with acid method) and
: down up and down.
:
: You may not get them out even with a
: breaker bar and a cheater pipe ! You
: may have to lift over and then heat and
: removed (double nut technique)
:
: It is usually the manifold sides that
: get coked up. I'm sure you got the
: rocket pedalistal off already
