1. How do you press the rods off and new pistons on ?
2. How much torque do I use when attaching the rod and bearing back on the crank? (Is there anything else I should know here as well)
3. Do I need new bearings?
4. If the cylinders look in good shape do I have to hone them?
5. Is it even wise to attempt a rebuild without experience?
Engine had less than 80,000 miles on it before valve seat fell and killed everything.
Thats about it. I have worked on cars doing various things over the years. But have never attempted a rebuild.

the same direction they originally did.
