Renault billancourt 4CV 58mm +30thou 16segment piston rings

[Prinsljn1972]

Hi I am looking for an oil scraper ring for a billancourt engine, this is the four segment piston variant, the ring I am after is 3.5mm high x 2.2mm width it is the 3rd ring from the top. Got the 6 slots not the 8 slots.
Happy to buy a full set if I cannot find the individual ring.

Thanks
Kobus

Hello and welcome to the forum, could you provide an engine number please?
The only engine with 4 piston rings is he 680 engine (747 cc) but the bore is 54,5 mm (not 58 mm as in your topic description) and two different pistonring sets.
The other engine is the 800 engine (845 cc) with bore 58 mm but only with 3 piston rings.

Aaahh the Billancourt 670 type rear installed engines. You will need MR 93 and look for the correct engine type in your Dauphine, as some types have convex piston rings
