Hi everyone,

I was taking a look under my engine cover today and found an oil leak at the OCV valve. Looks like this isn't a new issue as there is a few threads of people seeing this on the non-turbo 2.5L.

It's too bad this is happening on the turbo 2.5L as well.

Looks like it's been leaking for a bit as there was quite a bit of black gummy oil present on the front and back of the valve.

You may want to check your cars to be sure yours isn't doing the same.

My 6 just passed 100,000 kms.

OCV leak confirmed by dealer today and the appropriate parts are being ordered for replacement.

Sorry for bumping an old thread, but I don't think my post required a new thread. I've got a minor seepage on mine. 2018 GT in Canada, so GTR in the US. Only 18,500 Km / 11,500 miles.

It's been checked by my dealership yesterday and it's been noted. The tech said it was "very minor" and that they will keep an eye on it.

I wasn't expecting a repair, but I wanted to be sure they have it documented.
