Engine noise?

Normally a shop doesn't do individual parts on an engine unless it is under warranty and that is what the company requires. That is because in most cases you need to remove the engine prior to being able to take it apart to get to the bad parts. So rather than spending the time to take it all apart, and fix say a bad bearing, they will simply put in a reman engine that has a warranty on it so that the shop isn't on the hook if they replace the bearings but the metal going through the system also has damaged the cams, lifters and now those fail. Plus, in most cases it is faster and cheaper overall than trying to rebuild the existing engine unless it's a very minor problem. Consider that you are paying $100.00 hour. For labor to the shop. They removed the engine. Spend an hour taking it apart and then determine that there is a bad bearing, that means the crank will probably need to be turned, so now you are paying for that machine work at a third-party shop. While the engine is apart it should really be rebuilt so that means you also send the block out to have it either bored or honed depending on the wear, and the valves should be done so the head goes as well. Or they could pull it into a bay, remove the engine one day, bolt in the fully rebuilt engine the next day and you get a car back with essentially a new engine with a warranty three days after they start on it. VS about a month doing it the other way because most machine shops are booked pretty far out these days.

So yes, I would say to replace the engine.
