Piston rods, also known as connecting rods, are primarily found in internal combustion engines, where they connect the pistons to the crankshaft, converting linear motion into rotational motion. They are also used in various hydraulic and pneumatic systems, such as in hydraulic cylinders and actuators, where they transmit force and motion. Additionally, piston rods can be found in machinery and equipment that utilize pistons for movement or pressure generation.

The con rods
Yep!
They are cast and then the ends are machined to accept a bearing and the pin that holds the rod to the piston.
a press
8 dollars each to press new rods on pistons.
Push rods bend when there is no more clearance between valves and that no. 3 piston. There could be a foreign object sitting on top of that piston...or those valves set too tight.
The connecting rod has a "wrist pin" which goes through the side of the piston and through the connecting rod. It is one of the most critical fit parts of an engine.The connecting rod or con rod connects the piston to the crank or crankshaft!!!
I also had the same noise, and replaced the lifters, checked for play etc. After further disassembly it turned out to be from piston slap. On a few pistons the skirts had actually cracked off, but were still held in place due to the shape of the piston and direction of cracks.
connecting rod is provided between crank and the piston,which converts the reciprocating motion of the piston into rotary motion of the crank.
In a Chevy 350 engine, the piston rods should be installed with the wider end, or the big end, connected to the crankshaft and the narrower end, or the small end, attached to the piston. The orientation of the piston rods should ensure that the connecting rod's oil hole aligns with the oil passage in the crankshaft. Additionally, the piston should be installed with the correct orientation, typically marked by a notch or arrow pointing toward the front of the engine. Proper alignment is crucial for optimal engine performance and longevity.
Generally speaking, the crankcase is the lower part of the engine. It's where the crankshaft connects to the piston rods. If you drop the oil pan and look inside, you'll be looking at the crankshaft and the bottoms of the piston connecting rods.
