Bad valve lifter. The lifter no longer can hold oil pressure to push up on the push rod to the rocker arm to push down on the valve.

A worn camshaft will not change the static ignition timing unless the distributor drive gear is worn out. Is it possible that the camshaft is broken? Or is the timing chain or distributor bad?

i have a 95 chevy c1500 v8 200k plus miles. new battery. seems to short out and die, and wont restart. when key is turned on the amp gauge barely moves up. ive tried fumbling with the obvious wires (+ - wires etc) with no change. its done this once before. i let the truck sit for about a month then bought a new batt and problem went away. today while driving it died, with the same symptoms. also ive notice that when driving the blinkers make the amp gauge fluctuate down with every flash. thanks in advance for response 11 Answers
