Porsche Exhaust Valves
Hi,
Is there anyway if identifying genuine Porsche exhaust valves? Any stampings, numbers etc? TIA

Please go deeper here as i have done lots of valve jobs...
They in a bag? New, used? Valves live in the proverbial heill . I have got to the point unless very low miles I toss em. Every bit of material that is taken off the face makes for a hotter valve ( not in a good way) A burnt, dropped valve is not the way to save money....

They are new.
I've been told they are genuine Porsche ones but there is no packaging or anything. They have definitely never been used but just want to check.

There should be some finely engraved letters in the stem next to the grooves for the keepers. You may see ATE or TRW or something.

No markings on there at all, was just wondering if OEM ones do or dont have markings?

Divots can mean sodium, but members have cut some to find they are solid.
OE will often have the part number etched at the keeper groves/tip but this depends on year. TRW have the part number etched at the keeper groves/tip. I can't remember the intervalves if they are marked, I don't think I looked, they came in the original packing. I've seen solid stainless without markings. Take a magnet to the stem and to the face. I've seen magnetic face with SS stem...or was that the other ways around? I don't know it all, this is just what I've seen.
