That is one thing - the other which Phatdaddy alluded to - those drain plug gaskets are cheap and should be replaced every time you change the oil. If you fail to do this they can wear out, get brittle, compressed, etc. over time, leading to water intrusion. Bottom line if you aren't already, spend $5 on the drain plug gaskets at every oil change. I've been doing this for 15 years and never a sign of water intrusion with over 1000 hours.

I used to buy new gaskets and always had new screws if I chewed one up getting it off....or dropped it in the bucket of oil....
