Hello All. I'm new to this forum, and need a little info, if I may. I have a 2001 Pathfinder that I need to replace the engine in. There was a slight knock, and I pulled the oil pan off to investigate the cause, and the bearings were worn. When I took it apart, one of the journals was worn more than Nissan allows, so I just bought a JDM engine since it seemed cheaper in the long run than all of the parts I would have had to replace. The business I bought this from has an A+ rating with the BBB, by the way. It looks pretty clean, except I noticed it has quite a bit of what appears to be aluminum oxide on it, and I started to wonder if JDM engines are exported if the vehicle has been flooded, and what my engine came out of (the serial # is 806014A VQ35). There are a bunch of parts I need to change over. When I took the valve covers off, the heads looked very clean, which I'm very happy about. The dipstick looked clean, too. I hope the rest of the internals are the same. I also need to figure out if the compression is the same. Thanks in advance for any help you can provide.
