Default 99 Camry 4 cyl 60K service

Is a shim valve adjustment required on a 60k service @149.
Or is it just a dealer profit item?
How about replacement of spark plugs?
The car is 99 Camry 4 cylinder.

I have never had the shims adjusted in 185,000 miles on my
97 4 cylinder. I do replace the plugs every 60,000 miles.

Replacement of platinum spark plugs is called for at 60,000 miles.
Not a bad idea to change the valve cover gasket also - usually seepage
is occurring by 149K miles, and it's a fairly easy procedure on the 4
cylinder.
When the valve cover is off, it is a simple matter to check the valve
clearances. Only takes a few minutes with a thickness gauge.
Then, if needed, they can be adjusted by replacing shims - but if oil
changes have been kept current, this usually is not necessary. Good
idea to check the clearances though, just so you know they're ok.
While you're there, not a bad idea to change the PCV valve and grommet
also. PCV valve is inexpensive and simple to change, and by that
mileage the grommet is usually hardened and leaking slightly. Even
easier to change when the valve cover is off, so any broken fragments
fall "out" instead of "in".
Guess there's always something else. While the valve cover is off, I'd
also change the distributor O-ring to stem incipient seepage. Don't
know what a dealer would charge, but the distributor is only held by
one bolt. Changing the O-ring is simple. Then you just need to check
the engine timing. I suspect many techs just make a mark, but the
timing should be re checked - only takes a moment.
Also, at close to 150K miles, I'd be changing the distributor cap,
rotor and spark plug wires as preventative maintenance. You should be
using the stock wires and they are more costly that the other items,
but last a long time. Nonetheless, mine were creating a mild miss at
around 90,000 miles. Didn't notice it much while driving but the
resistance tested infinite and there was some shorting way down in the
spark plug tube where you couldn't see it.
Of course, if you don't mind the oil leaks, you could just figure the
valves are probably good and skip everything. My platiunum plugs were
still at the original gap at 60,000 miles, so conceivably they could
go longer, too. Depends in some measure on your maintenance
philosophy. I like to keep everything in good condition. Small defects
can be cumulative, where the overall condition declines or is kept up.

Thanks Robmurr and Daniel. I spoke to an independant Toyota mechanic
shop, very highly rated in my area, and he assured me that the valve
shim adjustment is unnecessary at this mileage. Also his total cost was
about $100 less than the dealer. I will be cancelling my appt. with the
dealer.
