I need a piston rod for a 99 grand am how much should i pay????

check oil level if low add oil ---if oil milky in color like chocolate milk possible internal damage from --blown head gasket-damaged head --the knock from engine usually means that damage to a piston rod has occurred [rod knock] and knock usually doesnt throw an engine code and usually fatal to engine will need a mechanic to diagnose how bad or what extent the noise is with engine

There is no way to repair push rods. If they are bent they need to be replaced. However, the hundred-dollar question is "Why were they bent?" The only thing that will normally bend a push rod is if the pistons hit the valves and compressed and bent the rods. If the push rods are bent, you should go the extra distance to inspect the valves/pistons for damage as well.

Shawn, any codes there, please reply.

remove engine from car and install on an engine stand, remove head and oil pan, disconnect lowe rod bearing cap and remove piston through the top, measure crank with a micrometer to get proper bearing size, install rod onto piston and install using ring compressor then install on crank shaft, lube well, reassemble engine and install in car

This is for a 3.3L motor
Hope this helps, it it does please leave feedback and vote Thank You and Good Luck

when u bent the push rod u might have bent the valve in the head ,by puting the longer push rod where it didnt belong it kept the valve open when the piston came up and the force of the piston on the valve bent the push rod,you will have to remove the head,hope this helps

You probably messed up a rod or caused piston damage your going to need more than a head gasket usauly when you over heat a car you causing the pistonts to expand more then they need to causing scouring and exsisive piston ware by the sound of it and the year your better off replacing the whole motor or completely rebuilding the old one wich will cost more then a use motor! good luck!

Likely you need more than one (not rod, but rod bearings) In most cases you get knocking noise and low oil pressure as symptoms. If caught early you can do this in-car otherwise engine needs crankshaft and all bearings as well as new pump and system flush.

Knocking noise is generally from the engine. What is your oil pressure? If pressure is low and oil is reasonably full, refrain from driving it till the cause is determined. Noise can also come from the transmission or transfer case but more likely it's from the engine.It can come from sticking valve lifters (moderately bad to potentially serious) connecting rod or main crank bearings (always serious) or piston slap (annoying, expensive but not terribly serious unless very bad) Piston wristpins can also knock but are very rare in todays pistons. Either way, this is not an item to ignore.
