Connecting Rod Bearings?

I have a serious question for the experts. My car is a 1986.5 w/ 7mge engine and 5sp. manual trans., 80,000 miles.

I have some symptoms of bad connecting rod bearings.
1. 3-5 second knocking noise at startup. Knocking under load between 2500 and 3500 rpm.
2. Slightly low oil pressure.
3. metal shavings in the bottom of the oil pan.
4. using correct grade gas, car has new plugs, wires, distributor cap, timing is correct, no smoking from exhaust.
5. From what I can tell the rest of the engine is in good shape (good compression, idles well)

Can the connecting rod bearings can be replaced without pulling or lifting the engine, and how hard is this to do?

I don't have the money or resources to replace the engine but I do like this car and would like to keep it running well without spending a lot of money.

What are your thoughts?
