Did you ever make any progress on this, Peril?
I am wondering if my Abarth might be suffering the same thing. Part number given is certainly correct although I can't find one for love nor money.
I'm wondering what makes up the internals of the valve and if I can fabricate my own (3D printer...) at this rate.
How have you got on?
Yes...and no. I visited my friendly FIAT parts department, only to be told that the PCV valve is '...no longer available...'. Sadly Stilos are now of an age where the manufacturer is no longer producing certain slow-moving parts.

It's not the kind of part any dealer would keep in stock.

You'll be surprised...!!
Anyway, all dealers can look into inventory/stock anywhere, even NLA parts...!!
It all depends on the willingness of that particular dealer, I found many parts, sometimes long NLA at different dealers that way, along the years...

Well I've scoured the entire world (not even joking) and I cannot find a supplier which has these in stock. Ordered from a couple of places only to be notified later not in stock. bummer.
The way I see it that gives me three options....
1. leave it, continue to drink oil like the Russians do vodka. Long term this will kill the car though.
2. Fit a restrictor in the valve's vac line. Some engines simply have this restrictor vs having a valve in place anyway, so that might help. Couple this with heavier oil and it should likely improve the problem. I can simple 3D print a basic connector with restrictor plate in it and place this in the vac line.
3. Fit a PCV valve from something else - this idea I like best. All valves are broadly the same so provided the tension in the valve spring isn't significantly different to that of the factory unit it'll work, assuming a physical fit.
To that end I've ordered a PCV valve from a Jeep. Unsophisticated American barn door engineering - they simply have an in-line valve in the vac hose. Cut the hose in half, couple of jubilee clips and in it goes - hopefully! I'll do a basic weighted deflection test on the valves to ensure they're acting at around the same tension. It's a £9 experiment if it's unsuitable so I'm cool with that little gamble.
I can test it on idle vac too to ensure it's passing vac back to the fannymould at max-vac (idle).
If it works I'll simply remove the innards from the factory valve, as they only sit in the manifold anyway and just leave the shell in place.
I'll see how that works out and report back, otherwise it'll be the 3D printed restrictor option.

Sounds like an interesting and useful experiment Artermis. Do let us know how it goes....
