Review on BMW 3.0L 2008-2013 128I/328I/528I Valve Cover W/ PCV, Gasket & Bolts 11127552281,11127582245 by Christopher Scales

I ordered this Valve Cover to replace a leaking cover, since these are known to crack with age.

After installation I have a PCV issue where the valve cover is pushing oil past the separator into my intake and causing oil burning and lean codes, I tried to contact the seller for a replacement or refund but we're going into 3 business days with no response and I have a vehicle I'm unable to use as well as having to replace a valve cover again.
