4.3 rebuilt engine for 2000 S/10

[1976gmc20]

Advice please!

My disabled friend down in Colorado has a nice 2000 S/10 that the V-6 engine apparently has a bad crankshaft(?) that is making it impossible to keep in time and he said it was "rattling" when he got it to the shop.

The shop is quoting $3800 for an engine and $1200 for labor.

I'm seeing a GM remanufactured engine from jegs for just under $2700

He is in Pueblo.

I'm going to call the shop myself in the morning!

It sounds to me more like a bad timing chain and sprockets, unless that has done more serious damage inside the engine.

The shop says that the crank bearings (and journals?) are worn out so that the crank is working back and forth longitudinally and causing the CPS to lose signal.

About $5700 parts and labor

I don't see how that would be possible. The engine would have already self destructed if the crank moved far enough to lose signal.

Thanks for the reply.

I don't know what to do? He is 750 miles away and besides $500 gas round trip I got hurt about a month ago and there is no way I can sit and drive that far right now. Not that I could even actually fix it, but maybe I could find another shop and help him tow it.
