well, you could take off the flywheel inspection cover, jam somting in the teeth of the flywheel and hold the engine. Again rope in the cylinder, really the BEST is to use the impact gun till the bolt stops....
My MAC TOOLS (lol) impact gun (while wearing my Snap on hat) worked fine without blocking off the fly wheel or using a rope, but that rope idea isnt a bad one
anyhow. i got it finished then while test driving i noticed a few problems im not used to.
the engine shakes like crazy while waiting at red lights (not that crazy tho) and it misfires once every 2 mins or so while waiting at reds. but the girl that owns it said it did this before... so i mentioned plugs. she said it was done not long ago -by her mechanic who is also her friend. who wanted $700 for parts alone on the timing belt water pump change. i got them for $300.
