I'm looking to replace the O-Rings on my 2009 G37's VCT Solenoids. I can't seem to find any OEM part number, it looks like I'd have to buy the solenoid which I don't need. Anyone know the size of the O-Ring? I'm going to pull the solenoid again to check it but it is 19mm-ish but I don't know the width.

I had an ugly oil seepage for the last few years and just cleaned everything up and replaced the VCT cover gaskets and coolant neck to timing cover gasket. My VCT Solenoids O-Rings aren't flat but are pretty close and I really don't want to clean up an oily mess again.

 

O-Ring p/n: 22131-ED000. Be warned, most US outlets will charge roughly $10 ea. (Cheaper overseas but with tariff crap and ridiculous shipping...)
