Engine Problem after Engine Swap
 

So here's what happened. I got an Rx7 NA, got into an accident and body is damaged beyond repair, but engine still good. Brought another Rx7, body in a lot better condition almost no rust but engine blew after couple months.

So I did an engine swap, and it went well except engine doesn't sound right when running and I smell some fuel from exhaust. Maybe fuel leak?? I posted an video, not the best but hope u can hear the sound. So, while swapping the engine, one of the plug from the engine harness broke off, dunno where it plugs into or what the plug is for. just hoping its an diagnosis plug, and the oil pressure gauge not working (u can see in the video), maybe a connection here??

Anyone have any advice on what I should do? I'm stuck and can't think of what the problem is. Also any suggestion of rotary expert shop in Chicago/Matteson area?? (just in case)

Thanks

On the upside, it does sounds like the Millennium Falcon...My apologies that this isn't helpful.

We will need pictures of the plug to figure out what it is.

The oil pressure gauge is probably just an unconnected oil pressure sender. You can find it near the oil filter, its screwed into the rear housing .

The engine, to me, sounds like it may be running on one rotor? Verify spark/fuel/compression for both rotors.

And if your looking for a shop, Shook Motorsports in Rockford.
