In regards to value on a RV what would the difference of a RV with 400 hours on a brand new engine and one with 400 on a 1st run overhaul?
Is the TBO the same on a Overhaul as with a new engine?
Things to look for on a 400 hour overhauled 200hp IO 360?
An overhauled engine done by a FLY by NIGHT outfit could be ready for another overhaul at 400 hours.
Or less... I bought an RV7 with a 200hr overhauled IO-360 A1A and at the first oil change (25 hrs) I discovered metal shavings in the oil. This led to a complete teardown for a metal contamination inspection. When the crank was magnafluxed, it revealed a crack. After further research, it turns that prior to the overhaul the parts were inspected by an automotive shop, and the overhaul was done by a homebuilder who failed to safety wire a couple of bolts in the accessory case. Now I get to buy a new engine because my wife has no interest in flying behind an overhauled engine.
Moral of the story, if you are going to buy an overhauled engine, do some seriously thorough research before hand. Obviously I didn't![]()
You should school yourself on definitions of "overhaul" versus new or "remanufactured. Legally, an overhaul is merely an engine that is inspected to service limits. On some parts there is a big difference between new limits and service limits. It's possible to measure out a high time engine and reassemble with almost no new parts and still call it an overhaul. This gives you virtually the same engine you had before you started. An "overhaul" in no way guarantees an engine that will give TBO service. Some "new" engines don't make it either but your odds are way better if your parts start out within new tolerance limits.
