Is the big nut (on the front crankshaft that secures the timing chain) held by Loctite?

In other words, would heating the big nut with a propane torch help in loosening it?

its held by torque, im thinking upwards of #300. long breaker bar (4 foot) and locking the flywheel is in order.

Yes, 300lb of torque could be considered loctite.

I believe Winfred has used the starter motor and a breaker bar braced against something to crack it. Sounds uhm...........winfred ;)

Well, two euro car mechanics of good repute here in town have told me they use the starter motor trick, for 20+ years, without ill effects. Still, it worries me.

would freak me out also but the starter motors generate quite the torque.

Is there anything I cannot remove with this setup?
