Chevrolet Astro

I have a 1999 Chevy Asrto Van AWD with 165000 miles. V6 Vortec 4.3 engine. Local mechanic tells me it has blown a crankshaft bearing. No one thinks it is worth repairing and to replace the engine means is difficult body work because the van body has to be removed from the sub frame to get the engine in and out. All local dealer/ mechanics say it is a lot of labor and not worth it. What do you think? Can I repair or replace the engine for a reasonable cost or not? Thanks, Fred
