Has anyone used oil scraper rings for top ring spacers? cutting the grooves to size is not a problem. Thans

I've had engines come in for rebuild that have had it done previously. No idea how successful it would be on a good bore, the ones I've seen were all on worn out bores and hadn't worked very well
What size bore and ring thickness are they? Might be a thicker ring available that the piston could be machined for.

Rover 3.5 +20 V8 Omega pistons, the top lands wont even take the earlier pre SD1 fatter rings, i see hastings in the US make spacer rings for this very task & say they must go on the top of the piston ring.

We did them on a Peugeot 2.3D engine, appeared to work fine, don't know quite what had happened but the bores were ok on that but the ring lands were worn
