1985 chevy Blazer cranks up, runs rough, then

1985 4x4 chevy Blazer cranks up, runs rough, then shuts off. Found a bent push rod, did repairs for that plus replaced timing chain and all other things I could think of, with no luck. Blazer still starts, runs rough and shuts off.

    Yes, compression was checked which led to bent push rod. Engine has around 94,000 miles. Drove car, it was fine. Next time I cranked it up, wouldn't run, backfired thru carb. What am I missing?

Have you checked, cady, fuel tank, is it getting the right amount of gas and air? plugs and wires, go with general mantinence first then step up. i have a 85 s10 blazer that was a lemon off the lot but has over 300000 on it and it has the same prob i fix it tempurary by flipping the lid on the breather upside down so it gets more air

What is causing loud knocking?


If you went off the road and the snow jammed into the engine compartment look for something bent and striking when the engine is on. If you find nothing bent or broken and the noise is coming from inside the engine you may have a bent valve or connecting rod. When an engine is abruptly stopped thing can get damaged. Take a wood shaft like a broom handle and place it near the bottom of the engine when running on the block and place you hand on the end of it and then place your ear on your hand and lesion for a knock. If in the bottom could be a bent connecting rod or also called a piston rod. If noise is in the top more likely and bent valve and the engine may run rough. If you not sure have a mechanic lesion to it. You can consult your repair manual for further test. Good luck.
