my friend has a 4.3 Vortec in a 1994 s10 blazer 4 dr 4wd, the spider injectors went bad and spun the main bearing. he was wondering how hard it is to fix/replace the main bearing.
thanks in advance,
chris

 

ok would it work if I pulled the motor and replaced the oil pump and the bearings if it would drive good enough to trade in. If that would work to fix it.

if your just goin to trade it in then do the oil pump, and if u want go to the auto store and buy some Lube Plate, put that on the bearing and then take it and trade it in asap, or just sell out right as is, because you prob wont get much out of it any way, and workin on it might be a pain in the ***.
