2006 Dodge Durango, 4.7L V8, 120,000 miles.
I am getting massive amounts of water in the engine (I just drained 5 gallons of oil/water mixture). The cause does not seem to be one of the usual suspects.
–3 years ago I noticed their was some water mixed in with the engine oil. After research, I found that there is a known problem with this model where the windshield cowl allows water to pour on top of the engine. I bought dodge’s upgraded cowl and the problem went away.
–1 year ago, I stopped driving the car. It has been parked, uncovered, in the driveway since then.
–2 months ago, I changed the oil and almost 5 gallons of water and oil drained out. I checked the radiator thinking coolant was mixing in, but the radiator was completely full. I replaced the oil, cranked it, and let it run for about 10 minutes. It has been sitting untouched in the driveway since.
–Yesterday, I checked the dipstick and there was white frothy oil way above the full mark. I drained the oil, and again drained 5 full gallons of oil and water. I again checked the radiator and it is completely full. I changed the oil, cranked it up and let it run for over an hour. I checked it this morning and the oil looks perfectly fine.
I am at a loss. How could this much water be getting into the engine oil when the car has been parked in the driveway not running? My first thought was coolant, but at this point I’ve drained several gallons of water and the radiator is still full. The only other source that I can think of is rainwater. Is there any way that this much rainwater could accumulate in a parked car over two months? If I had a bad gasket or a cracked block, could rainwater be getting in that way?
I’m at a loss. Thanks in advance for your help!!!
