Valve Adjustments

[Lewis]

my service book on my 2009 calls for it @120K miles. At that point the car will probably be worth so little I'd be inclined to just drive until it dies.

If you read PK's link on what that checkup entails you'll see that its an audio inspection meaning if your valves arent making any abnormal noise then they're ok.

A valve clearance inspection is not a "audio inspection"!!! It's a physical inspection using a feeler gage to measure clearances. What if your valve clearance is too small? They wouldn't be making any noise then, yet undersize clearances can burn out your valves!

Don't depend on noise to determine if the valves are OK. It can't be done.

Heres the link to the maintainance schedule check out the 7th item in the 64k inspection http://xws.xtime.com/xmmmenu/?varian...estimate=false
I agree not much of a valve inspection.

And Mitchell repair says to LISTEN for noise, then check for engine smoothness, before going to the actual trouble of pulling cyl head cover and checking clearance with a gauge.
