I drilled out my pvc (2.9 whipple) and still had it connected to the vacuum on the supercharger via a catch can , big mistake, instant smoke show at idle , blanked of the vacuum fitting and fitted a filter , all good, I’d fit the upr caps on the manifold
yeah having an open port in your PVC attached to vacuum would draw lots of oil out causing smoke. The UPR caps don't seem to provide a great seal to me, I can see my vac/boost gauge flutter when I rock the UPR cap on the manifold fitting. The rubber vacuum fitting doesn't leak. Vacuum/boost leaks are no good.
could you post the link to this exact catch can? i can’t tell if it’s the strut brace mount one or not. They look the same to me but the prices are different so i’m not sure . Thank you
This is the one I have. I also got the billet adjustable PCV valve option. www.lethalperformance.com/upr-billet-dual-inlet-breather-tank-plug-n-play-oil-separator-catch-can-black-2011-2023-mustang-gt-5029-221.html?gad_source=1&gclid=Cj0KCQjw2ou2BhCCARIsANAwM2FBpXs7eiT37b2YEHLNY2ok3WpXVH1Uuz5yl1iFq9WO3BG8_pjQLMkaAsCuEALw_wcB
