Do I really need my engine replaced?

My Daisy, an 02 MT with around 210000. Cant take inclines without losing power, rpm drop randomly and frequently, sometimes shutting off altogether? Dealership tried to sell me a fuel pump assembly after the fuel pump was replaced. One shop couldn't figure the low compression issue though after cleaning out every part where oil could flow, repaired a slight leak in the gasket. And the last shop is saying engine replacement since compression was lost in one cylinder and there appears to be damage in that and another cylinder caused by bad rings.

Honestly a new engine is quite costly. I asked about a rebuild or fixing the bad parts; was told that that work would equate engine replacement seeing that machine shop and such along with honing the engine would be required. Easier to drop new engine with everything machined and ready to go.

Can I have some input please? I dont want to let go of more money to have another issue later.
 
used engines can be had for about 600 bucks, and another 400 for the install. so you are looking at $1000 bucks, i say if everything else in the car is good. replace the engine, and drive it for another 100k. a used comparable car will cost you a lot more.

I have about 220k, good compression. if my engines dies, i think i would spend the 1k to replace the engine
 
If you have loss of compression, and you have that many miles on your car, and you have noticeable loss in power, then it sounds like you need a rebuilt engine or a replacement engine. Regarding the rpm drops and shutting off, that might be related to other things, idle air control valve, exhaust gas recirculation valve, leaking vacuum tube or something else.

Engine rebuild is a labor intensive job. The engine would need to be completely torn down to replace the piston rings on the cylinders.
If you do buy a rebuilt/remanufactured engine, you have to pay a core charge until you return the old engine. You could buy it without a core charge, but then you pay more upfront.
