It will depend on how large the issues is. Try new seal, maybe copper seal? before you go KClemente route which is quite possibly permanent repair.

I have recently run into this exact problem as well. wondering if anyone make a full stainless sleeve that can be inserted into the port after you ream it out oversized. much like a sleeved cylinder. If you pressurize the cyl with an air line into the spark plug (make sure valves are seated) you can eliminate any debris and shavings from dropping into the cyl. but you would need a reamer to cut away the worn aluminum in the port. then take a cold sleeve (fit tolerance) and drop it in then the injector should NEVER wear the port ever again.

thoughts? would imagine someone with a lathe could make the sleeves. the reamer would be tricky though.
