Thank you for the donation,
Firstly I am not that familiar with theses cars as I am in Aust, but what you describe sound like an oil filter draining back, the engine will take a few sec to re establish full oil pressure with the filter empty, are these filters inverted? You may wish to check out filters that have an anti drain back valve. Start here.
