Having problems with your 1993 Chevrolet S-10 Blazer ?

I have a 1993 chevy blazer 201000 miles. It is the 4.3l CPI Vortec engine. The car has been running great even though its a beater, I recently replaced the pcv valve, fixed the leaky oil cooler lines, put an aftermarket air filter in because the old one wouldn't fit with the new oil cooler lines to the radiator. I flushed the radiator, tranny fluid, gave it an oil change,changed the fuel filter (which had pressure), changed plugs, wires, cap rotor, ignition coil, S-Belt, added some lucas fuel

Answers :

First remove the plugs and try to turn the engine by hand(slowly), if the engine locks stop, remove valve covers and check each valve keeper, i think you may have dropped one , if not a nut or washer may have found its way into the piston chamber
