One possible way to tell if the engine is new, is to look at the bolts holding the top and bottom of the can together (there are 38 of them, should be grade 8, sometimes grade 5). If the paint is undisturbed on the bolts and nuts, the engine is probably new. that's because the can has never been opened. Another fairly easy way to test is to get a pressure reading or look for the moisture indicator. If it shows any trace of moisture inside, or if there is no pressure (should be 5 to 7 pounds of dry nitrogen), it has probably been opened, and likely has a swapped engine inside. Likewise, if all 38 bolts are not there, it has definitely been opened. And opened in service means an engine swap!
