HI guys really need some help here I'm going nuts here. , I'm trying to rebuild a 2.2 Alfa motor here in Australia
Just seeing if anyone knows the radial depth for the first compression ring as we only have z22se here and they are too thin at 2.7 mm. Looks like it needs to be 3.5mm
Thanks guys

I have measured a few and they are the same size, but I guess it depends on where the engine is made and if GM decided to use a slightly different piston ring on one engine.
