At a shop a complete engine rebuild is about 40 hours of labor. It's a very big job. You might not need a rebuild. Where is it leaking from? You may be better off diagnosing the leak(s) and replacing the offending gaskets. HTH. -Jim

An engine rebuild is NOT something a beginner should tackle. There are many items that need to be measured to a tolerance of .001". Cylinder taper must be calculated or measured, cylinder size, crankshaft rod, journals, crankshaft main journals, crankshaft run-out, crankshaft end play and valve guides / stems must all be looked at. I would either buy a rebuilt of look for a good used engine if I were you. Perhaps someone you know or a relative has the knowledge to help you.

Is the vehicle itself in good shape? The truck is 35 years old, if in good shape I'd invest in a remanufactured engine from a reputable company who does remans. If the rest of the vehicle is not in so good a shape just find a used engine.
