GD on yA, last week i just found out my 07 STi was leaking oil from the oil filter COOLER . Took it down to Melville Subaru, and they said the seal on the oil filter is not properly fitted. And theres a chance it wont be warranty because i got my exhaust done and someone have messed around with it.

So i went to complained to the Dealer Principal that there's no way that the exhaust people would touched anything near the oil filter cooler or the cooler itself . After few minutes of argument, they finally decided that it is warranty.

O6 / 07 STi OWNERS, Please check your dipstick oil and make sure that the oil is on the FULL line mark! It could be that your car is leaking oil
