You are not going to like the answer. But the only sure fire way to to tear down the engine at the very least pull apart the top end that is, the cam and lifetrs and with the oil pan droped you can push it back thru the block and it should fall out. After that the only other way to fix it, is to get a pump block off plate put it on and go with a electric pump.
Gonna have to pull the head and find out what's wrong. Could be a bent valve.
That engine is pushrod, it is the GM 3100 if I'm not mistaken. What are symptoms because bent valves are unlikely.
A bent engine piston is a reference to the piston rod. The piston cannot be bent, but the piston rod can be bent.
yes definitely, bent 4 exhaust valves on my 98, and she was locked up
To remove a bent fuel push rod from a 350 engine, first, ensure the engine is cooled down and disconnected from the battery. Then, remove the necessary components, such as the intake manifold and any associated parts, to access the push rod. Carefully extract the bent push rod, and inspect the lifter and related components for damage. Replace the bent rod with a new one, reassemble the engine, and ensure everything is properly aligned and secured.
NO it is an interference motor 180,000 broke timing chain, bent #3 exhaust valve, luckily it must have stopped quickly as no more were bent.
Yes it does if the belt breaks you will most likely need a new engine, because the valves will be bent up.
A bent hammer
Cracked or warped heads, motor block, Bent valves, blown head and/or header gaskets worst case locking up the engine.
To replace a bent push rod in an engine, first, ensure the engine is cool and disconnect the battery. Remove the valve cover to access the push rods, then carefully take out the bent push rod, noting its orientation. Install the new push rod in the same position, reassemble any components, and ensure everything is torqued to the manufacturer's specifications before reconnecting the battery and testing the engine.
it did in mine it bent 2 valves and i end it up replacing the head on it
The year and engine size would help but you may have a bent valve or bent pushrod for # 4 cylinder if that is the only cylinder that has 0 for compression.
