Has anyone ever heard of the oem metal gasket failing. I have about 10k miles on a rebuild. I went full non-seq with a street port. It runs good and at first everything was solid. Now it seems that I have a leak somewhere. There is a noise kind of like pressure releasing as a bov would after letting off the throttle. Its coming from the secondary turbo it sounds like. Also have a fuel smell after a wot run. any ideas???

 

even metal gaskets need changing sometimes
