Knocking engine replacement planning

I got a Knocking Engine I'm planning to replace in my Elantra '09. Dealer said to ignore it as long as the noise got lower once the engine is at operating temp. Well, 20kmiles later... it's getting worse. Sounds like someone hitting the engine block with a hammer. Still pulls strong and no oil consumption noticed, but really annoying and would most likely be unsellable as it is now.

I don't think "open surgery" would be cost effective at this point and I'm more looking into dropping a lower mileage, salvage yard engine in it instead.

(Also, here in Canada, we didn't get the 10yr/100kmiles powertrain warranty... just 5yr/60kmiles)

Service manual says the engine cradle needs to be dropped for this, and the A/C purged/refilled... and that makes the swap more difficult/costlier than it should, IMO. (A/C refill in Canada is Certified Shop only, and comes with heavy price tag) Has someone here experienced or seen info about doing it from the top, just moving the A/C pump away from engine?

Thanks for any ideas

2009GLS is an unknown quantity at this point
Sure, you could, but also you must remove the hood/bonnet.

In order to accomplish it you may need to remove the radiator fan as well. Keep in mind the engine gets wider down towards the bottom.
