Hi all, I have a 2004 OB Limited that is starting to over heat,took it to my repair guy and he said that it might be a cracked cylinder (head gasket done at 138.k by him, car now has 172.k) walking out of the repair shop I was feeling dejected so I decided to get a 2nd opinion and took it to a sub dealer. Besides needing a radiator, cat and brakes the dealer noticed that the Hg where leaking. So with this info I went back to my repair guy and asked him why he thought it was a cracked cylinder and not a HG issue and he begins to give my reasons why it might be otherwise (Which was greek to me) Anyway the work he did on the HG is still under his warranty. So heres my dilemma should I insist that he do HGs? What if it's a cracked cylinder and how common are cracked cylinders? Thanks in advance.
