CamaroZ28.Com Message Board - Rain Water getting in oil while parked!!

Starting June/2012, every time it rains, plenty of water ends up in my oil while my car is parked. I first noticed it when I started my car one day during a heavy rain. Shook, sounded terrible, turned the car off after being on for 10 seconds max. Once the rain had stopped I checked the dipstick--milky looking, clearly water in the oil. Changed the oil myself and removed 13+ quarts of water/oil. There is also standing water on the drivers side rear front/rear floorboards. How could this be?

The following time it rained, I noticed 2-3" of standing water where my car was originally parked(moved it across the parking lot), which could explain how the water got in the oil the first time. After the rain stopped, I checked the dipstick, oil looked brand new. Before starting, I took the drain plug out and it was pure water at first, could have drank it if I were thirsty. No standing water this time, or anytime after. Still had 2+quarts of water each time though. I changed the oil/filter several times before buying a cheap car cover at Walmart 3 weeks ago. No more rain water in the oil!!!

However, yesterday I drove to the grocery store and on the way home and noticed a burning oil smell, looked at the gauges and my oil pressure was around 20. When I parked my car, I noticed a trail of oil--the oil filter was leaking oil. Changed the oil filter, started the car and now I have 0 oil pressure and the oil pressure sensor is leaking just above the oil filter!

Got a new oil pressure sensor at NAPA, waiting to replace it until its not dark.

Any ideas as to what this could be?
