Buying Engine overhaul package by OE number
An overhaul component set, and this shelf holds a piston ring set in 79.5 mm for the Renault Clio and Megane K4J and K4M engines. It is a set of rings for one engine size, not a complete overhaul kit.
The category carries 1 reference. Rings are matched by the bore diameter, the ring width and the engine code, and fitting the wrong set gives high oil consumption or poor compression. The bore must be measured and honed before fitting, and the ring end gap set to the spec. A ring set fitted into a worn or out of round bore will not seal.
Frequently asked questions
Is this a full overhaul kit?
No. It is a piston ring set for the K4J and K4M engines at 79.5 mm.
Do I need to hone the bores?
Yes. New rings need a cross hatch to seat, and the bore must be measured first.
How do I set the ring gap?
To the maker spec, measured in the bore. Too tight a gap breaks the ring.
