| |
| − | This page will give the buyer of an engine that's new to them a list of things that should be checked/confirmed to be within specs '''before''' using the engine. It is intended to be a general guide, not all these things will apply to all engines and the list might not be all-inclusive.
| |
| | | | |
| − | ==Let the buyer beware==
| |
| − | In almost every case of the casual sale of a used engine, the sale is considered to be on an "as-is" basis. So regardless of what might have been said or inferred about the engine condition or specs or what parts an engine may contain, it is the new owner's responsibility to check the entire engine over to be sure it's what it's supposed to be, or if it needs additional work or parts in order to be usable.

| |
| − | • '''[http://www.crankshaftcoalition.com/wiki/Valve_train_points_to_check HERE]''' is a list of valve train points to check, including the valve train geometry. This doesn't require any disassembly other than the valve cover to be removed and should be checked ''before'' tearing the engine down.
