[Spits] Timing chain cover nut

[Nolan]

Use a 3/4" drive breaker bar.  A 1/2" flexes so much that it doesn't do 
nearly as good a job at removing the nut.

Don't try to use the parking brake or such, there's way to much flex and 
wrap up.  You won't get the nut off this way.

I tend to use the starter motor myself when removing crankshaft nuts.  Put 
the socket and breaker bar on the nut, positioning the handle of the breaker 
bar against a frame rail or such.  Bump the starter motor.  The nut spins 
off.

If that gives you the heebe-jeebes, Rotate the engine until the #1 cylinder 
is on the bottom of the power stroke (1/2 revolution past TDC, with the 
distributor rotor pointing at the #1 cylinder wire.  Stuff rope down the 
cylinder via the sparkplug hole.  Rotate the crankshaft backwards via the 
nut.  The piston will push up against the rope, locking the engine, letting 
you pull hard, breaking the nut free.
