The Accent 1.6 GDI owners manual says to inspect valve clearances at 60 K miles. Anyone with that mileage done it, were the valves still in spec? Reason I ask is, because (according to the service manual) the camshafts have to come out in order to adjust the value if needed. I've had to do this before on motorcycle engines, a bit of a PIA. Hopefully the valves don't change enough to require adjustment. Thanks.
