Wow, Im not sure 300 bucks will get the engine pulled. Much depends on
the condition of the crank. If it needs turning (probably will), plus
the cost of a gasket kit, seals, and labor, you are looking at way
more than 300 bucks. Id get estimates from a few mechanics before I
take it in.
If you can do the labor yourself, 300 bucks might get it done. Theres
not that much to a bottom end, make sure each rod/main cap goes back
to the same place, use a litle STP on the new bearings, torque
everything down. Oh...just for kicks, Id replace the oil pump, you
never know, that could be the weak spot that led to bearing
failure...and take the crank to your local parts house have them check
its tolerances, and turn if need be. Then they can match up your
bearings.
=2E..now back when I was a teenager, I replaced my mains/rod bearings in
my old 67 Chevy truck, lying on my back, in the gravel, with the motor
still in the truck. (straight six) Of course these days, there not
that kind of room underneath one....
