Oh . I will stop guessing what your issues are.
If you want to give us half a chance at helping you post some pics of engine bay.
Why would a custom pod mean you don't have a heat shield on your turbo or manifold?
Yes, ffs, fit the stock bov. It will mean it won't make annoying hectic noises, or make your car idle like shit, or spray oil all over engine bay due to massive blowby issues you seem to have, and you won't get a defect.
I haven't suggested it to you numerous times because it is pointless and won't help.
