How many years can connecting rods last after being replaced due to engine water ingress?
2 Answers
After replacing connecting rods due to engine water ingress, they can last about 10 years. Introduction to Connecting Rods: Connecting rods are components that link the piston to the crankshaft, transmitting the force from the piston to the crankshaft and converting the reciprocating motion of the piston into the rotational motion of the crankshaft. Structure of Connecting Rods: The connecting rod assembly consists of the connecting rod body, connecting rod big end cap, connecting rod small end bushing, connecting rod big end bearing, and connecting rod bolts (or screws). The connecting rod body is composed of three parts: the part connecting to the piston pin is called the small end; the part connecting to the crankshaft is called the big end; and the rod connecting the small end and the big end is called the connecting rod shank.
How many years can connecting rods last after being replaced due to water ingress? I often discuss this with fellow car enthusiasts. I remember my car stalled suddenly after driving through water last rainy season, and the repair shop found the connecting rods were bent. After replacing them, it's been running fine for over two years, covering about 30,000 kilometers. However, the mechanic warned that water ingress can cause crankshaft rust or cylinder wall scratches, and simply replacing the rods doesn't address other potential issues. I change the oil regularly and monitor engine sounds, addressing any unusual noises promptly. Under normal conditions, a good repair might last three to five years, though not as durable as the original parts. Overall, it depends on the depth of water ingress, thoroughness of the repair, and maintenance frequency. Minor water ingress isn't a big deal, but severe cases may lead to quick failure even after rod replacement. Driving habits also matter—gentle driving can extend lifespan. In short, don't expect it to last as long as a new car; replace when necessary.
