Technical O ring for fiat 500 pcv valve assembly

[Dannyg1987]

Hi all. We've had a bit of oil under the car recently on the sump and gearbox but neither are leaking. We've changed the rubber seal that goes into the air intake underneath the air filter, but I've read that underneath the air filter, there is a pcv valve air/oil separator with an o ring that is prone to fault, given the car is 13 years old it's possibly this and I could replace it. I just can't find the o ring suitable for it if any one knows? I'll put a picture up if it helps. I've only seen o rings available in the USA, none uk based unless its probably a fiat dealership.

Any help is much appreciated.

Depending if suitable dimensions etc. but O ring kits with a variety of sizes are available on eBay.
I needed two small specific O rings for the oil cooler housing on a Doblo1.6MJ and ordered them from a Fiat Dealership, two weeks later they arrived in a Fiat sealed plastic bag marked PRC (Peoples Republic Of China) at a cost of around £37, so not impressed.
Subsequently I bought a O ring making kit from Loctite, at first a bit sceptical but it has paid for it's self many times over, plus different thickness and even square section of a suitable oil grade etc. are readily available online in lengths so you cut a correct measured length, follow the instructions and job done!.
