The job will cost a few hundred dollars at a dealership, almost nothing if you do it yourself. The job is fairly easy if time consuming. It can be performed with a normal set of metric sockets, a feeler gauge, and a micrometer. However you will need a special set of tools called a Valve Clearence Adjuster Set. Toyta parts number 09248-55010, or equivalent. The actual Toyota special tool set is extremely hard to find however a generic set shouldn’t be too tough.
Do not attempt this maintenance without a way to depress the valve lifters.
Required tools:
- Metric Socket Set
- Micrometer
- Feeler Gauge
- Valve Clearence Adjuster Set-or-generic replacment.
