Not to mention you have then gone from being an innocent owner of the unidentified engine to fraudulently modifying it by putting a knowingly incorrect number onto the engine, which could then land you in trouble should the real identity even become known. The number you put on has to match the manufacturers database which will be used to confirm identity and valuation so a Post code won't work. It would have had a number at some point which begs the question why has it not now ?
I'd sooner run with no numbers than a fake one. Yes I understand your points regarding getting paid out but at what cost ? In the end your just putting up premiums for everybody else and providing an outlet for stolen engines. Simply remove markings and put your post code on it then it's yours, right ?
Let me make it clear though I do not believe the engine in this thread is in any way suspicious. I trust the seller from previous dealings I've had. Stickers can and do fall off. This is a general comment.
