What could be the cause of rain water getting in the engine? I had to replace the computer unit and electrical relays three months ago due to water in the engine and it just happened again this past weekend.

Please help!

Is someone washing your engine...or driving your car through rain-swollen streets?

Not at all. The car is parked in front of our house. This happened in June and we had to have the computer and electrical relays replaced ($4500). Now it has happened again. Removed over 1 quart of rain water from box underneath computer unit with a turkey baster and more water drained when car was towed. I've had the car for years and had major rain storms and nothing like this ever happened. Can't figure out how water gets in the engine.
