Troubleshooting & FAQ
How do I know if these piston rings will fit my engine?
This aftermarket Piston Ring Kit is designed for specific Volvo Penta gasoline engines, like the AQ145A, and replaces OEM part 275331. Always verify your part number and the required ring dimensions (1.75 × 2.0 × 4.0 mm) against your service manual before ordering.
What are the signs of failing piston rings?
Common symptoms of worn piston rings include excessive oil consumption, noticeable blue or gray smoke from the exhaust, a significant loss of engine power, and poor results from a compression test.
Are these rings a standard size?
Yes, this is a standard (STD) size piston ring kit. It is intended for engine blocks with original cylinder bore dimensions and is not suitable for oversized bores that have been previously machined.
What is the proper orientation for installing these rings?
Most piston rings have a top-side marking (e.g., a dot or letter) that must face upwards toward the piston crown. The exact order and ring gap positioning are critical; always consult your engine's official service manual for detailed instructions.
