So that raises the question: do I wait until my first 12,000 miles to check it, or 18,000?
I've got my 6,000 mile service coming up, I have no idea if my local dealer will insist on the valve check-- I fear they will, they strike me as a bit of money-loving stickler outfit, but I'll push back. A valve check at 6K seems really, really overkill, especially at that price.
