Friday after work I decided it was time to change the air filter in my X. Whenever I do any maintenance on it, I give it the once over to look for other things. I noticed two small coolant puddles underneath. All I could see was that coolant was dripping off of the starter, so I grabbed my jack and flashlight to see where it was really leaking from. Unfortunately I found that it was leaking from the seal where the block and crankcase bolt together. The two rearmost bolts on the passenger's side have nice little lines of antifreeze/water mixture dripping out. I take her in today to Bergstrom Nissan in Oshkosh. We'll see how they deal with it. Will post more after I know more.
