My buddy's si came into the shop the other day 1000 miles after an oil change and oil was leaking from the filter area after checking it out longer i determined that it was the oil cooler seal. he has about 15k on his '07 4dr just something you should watch out for. may see more warranty.

 

the coupes had an issue with that in 06. Probably the same situation.

 

Couple of us are leaking from the vteck gasket and valve cover gasket area also. Everything is being warrantied.
