I ran my car for 5 years and about 18,000 miles with a small pan and OE windage tray. At around 18k, I added the 2000 windage tray and trap doors, and kept the 1 hole OEM sheet metal plate over the screened pickup. The returning oil can only get to into the pan right above the pickup. I now have almost 33k miles over 14 years. I've pulled rod caps for inspection with no problems encountered. I'm also one of those guys who only changes oil about once every 12-18 months. Your mileage may vary.
