Was getting ready to drive to San Antonio and my check engine light came on. Took it into the dealership and got some bad news. The guy said I had a burnt valve in the #8 exhaust. He said something about if you replace one side you might as well replace the other side. He said it would be best to replace the whole cylinder head. He called me back with a price and he said $7,147 to replace the cylinder head!!!!! Or he said I could replace the whole engine for $6,600. I definitely want to get a 2nd and 3rd opinion cause I know nothing about vehicles and plus they're pretty much the only place in town so I don't know how much he's trying high ball it. Anyone have an idea about what's really going on from what I've explained? Thanks in advance.
