94 Sable, bad connecting rod bearing

My 94 Sable is making a clanking noise for the past few months. A mechanic told me it was a worn bearing at one of the connecting rods. He also said that I would probably be better off buying another car because this repair
is expensive. How long may it last? I know a weel bearing could go making noise for months even years.
In the manual, it says a connecting rod or its bearing can be replaced by removing the cylinder heat and oil pan with the engine in place. I have done it before on a smaller car, the cylinder head only. In this case, would this repair be difficult? If the car could make it for a few more months and I decided to do the repair myself, I would wait for the Spring when it is warmer.
Thank you

If its making much noise it will probably seize or spin on the crank in a few days.

You might have been able to fix it like this if you caught it very early but I doubt it. What happens is the bearing gets loose and ruins the crank journal it runs on. I don't think you can replace the crank with the engine in the car.

Yeah, if it's a rod bearing I doubt if it could go on for months. It might just be a bad lifter or loose rocker.

Until it locks up at 50mph, you pull thru a couple of lanes and take that nice family out that were waiting at the bus stop.....

Your welcome
