Neil,
Before you do anything else, put the car in 4th gear instead of 1st, then
give it another go. There's a whole more 'winding up' of the drive train
per turn of the motor in 4th, yes? That should decrease the 'springlike
tension' you're feeling. Hopefully this will take up enough slack to get
the nut turned before you run into the fender with your breaker bar and
cheater.
As far as the 'popping' noises, the motor puts a lot more horsepower
through the drive train than you or I could ever hope to, doesn't it? I'd
climb under and have an assistant make the clunk just so I could see what it
is, but I doubt you're hurting anything.

Hi all,
A real quick message as I have no time to look at Email - off to NZ for Xmas
tomorrow. Merry Xmas and Happy New Year to everyone! :)
I finally sourced a 1 5/16" socket and a 3/4-1/2 Adapter (not easy to find
here!) to undo this crankshaft/harmonic balancer bolt. Someone recommended I
loosen this whilst the engine is still in the car. Ok - with a metre pipe
extension on a breaker bar, when I turn the bar there is considerable spring
like tension coming from the crank - with the car in first - the gearbox
doesn't sound too healthy at all. If I apply a lot of force there's a clunk
or two from the box (well back that way anyways), making me wonder how
healthy it is to put so much stress on the box. I haven't tried with all my
might to loosen the bolt because of this 'spring' like tension I'm feeling -
I figured I'd ask before I stuffed something! <G>. I'm turning the bolt
anti-clockwise, I've whacked back the locking plate. I also seem to run out
of purchase because the shaft is turning and not locking, if you catch my
drift, the pipe under full tension gets close to the fender not leaving me
much if any room to loosen the bolt.. All of the pistons are out of the car
btw so less friction going on here.
Am I doing something wrong? <G> Whoops I mean, what aren't I doing wrong.
<VBG>
Xmas Cheers,
Neil.
