Have any 5th Gen owners experienced a head gasket failing? This mechanic says the 4th Gen 4.0L Toyota engine (5th Gen also has) has a problem with head gasket failures over 120k miles???? I’ve never heard of this being a common failure on the 4.0L engines. My 5th Gen has 130k miles on it so this video has me a little worried. I change my oil every 5k and change my engine coolant every year (overkill I know) other than that how do you prevent this from happening? Thanks.
