Quick question for those who have personally experienced this situation: my friends 2800 coupe, after swapping what we thought was a good motor, has oil smoking out the tail pipe. I talked with 2 of the best authorities on these situations, Terry and Don, and both of them agree that it is odd to have good compression numbers (155-165), and smoke still coming out. The motor has now run for 2.5 hours. The oil rings may not be sealing. This engine apparently sat for many years. So far the plan is to soak the pistons in carb cleaner or atf for a few days. Any other suggestions worth pursuing, please let me know.
