What the AI looks for in Automotive Replacement Engine Piston Liners

Wet vs dry liner: Replace like with like. Wet liners touch coolant and seal with O-rings, while dry liners press into the block bore. The two designs install and seal in different ways and are not interchangeable.
Liner protrusion (wet/flanged liners): After installation, measure liner height above the deck and keep it within the engine maker's specified range, consistent across all cylinders. Wrong or uneven protrusion leads to head gasket failure and coolant leaks.
Interference fit (dry sleeves): Machine the block bore to the sleeve maker's specified interference, then bore and hone the sleeve to the final piston size after installation. Too little interference lets the sleeve move or drop, and too much can distort or crack the block.
Flange style and wall thickness: Match the flanged or flangeless design and the outside diameter to the block counterbore and the intended final bore. The final bore size and how the liner is located both depend on these dimensions.

Reusing old liner O-rings or seals.
Installing dry sleeves without a machine shop able to bore the block and finish the sleeve.
Skipping the protrusion check on wet liners.

Yes, single-cylinder sleeving is a common repair, though the sleeved bore must be finished to the same size as the others.
