The reason it seeped through (like stated above in previous posts) is becasue the leak was already present there....Dyno oil leaves deposits that can fill leaks.
Synthetic oil cleans out thoes deposits and makes the leaks noticeable...By not taking car of the leaks you can have a bigger problme later than now. people thinking that synthetic oil causes leak, is a common misconception.
