well my warrenty is a 1 year unlimited KM, I would like to renew it I dont think they will though, as far as I know the head gasket has not been done yet nore is going to need to be (crossing fingers for good luck) I show no signs of problems, I was just talking to my mechainc about oil's he said that they can contribute to a leak if you switch back and forth from regular and synthetic, i got one of these crummy shop manuals off ebay so i can have some guide lines befor i go into repairs blind
