Have them remove and clean the oil pickup and its screen and remove most of the crap from the pan. Put in a good oil, perhaps Rotella Synthetic 5W40, good for gassers but marketed for Diesels*. Walmart has this for $12.88 a gallon. New oil filter and get a can of oil addative that claims to free up sticking rings**. It will be around 10 ounces and will be watery when you shake that can. It is a solvent. Put that in and run for a few days, new oil and filter, then the AutoRX. You might get their special on 3 bottles. Keep doing the AutoRX and maybe some more solvent. By the time you are done you will have run around $100 through the engine. Its worth a try if the alternative is a new-used engine. I would not spend money on it that would double its book value! After that run Mobil 1 0W40.
* This oil has more friction modifiers that will help the engine get through the transition period.
** Add immediately, not later that day
Run the AutoRX for the duration suggested for the first bottle, and longer on the subsequent bottles.
If the above does not work, you have the satisfaction that you did explore that option.
There will be a bill for pulling the pan. So you are not off the hook yet. For a bit more the can pull a couple of rod caps and bearing caps and tell you and show you if the bearings are trashed. If that has happend, not much can be done short of a rebuild. If the crank journals are bad (the steel side), it might not be worth rebuilding. That is where a used engine makes sense.
