After approx 26 years my oil pan on the 70 Z28 has a few drips and started only about 1 year ago. Pretty darn good on cork. So, I do not want to pull the engine.... can but don't want to! I know most of all the particulars but need so opinions.... always good to have others views. So, I'm thinking about using my bottle jack and a small piece of wood and use the balancer as my jacking point. I worry about mashing or damaging a main bearing? Damage to crank.... would any of you been down this road before with the balancer as a jacking point? What say you?
