Out with the old and in with the new. The original aluminum 3.9L V-8 that came out of the Rover would run on ether, but it sounded horrible and most of the EFI wiring harness looked rotten. At the same time the engine and heads look new, and there were several glue-on temperature sensors that engine rebuilders add so you can’t run it super-hot and then bring it back for another when it blows a gasket, indicating a recent engine replacement from a mass rebuilding company. Editor Hazel wants to steal this engine and install it in his Project Why-J 1989 Wrangler to see if it’s toast or not. We’ll let you know.
