Guys some important feedback regarding Injector seal leaks that can lead to Oil pickup Screen clogging & engine Failure.
I have been recently advised by a Toyota representative that in Australia, as is the case in New Zealand, It is a requirement that service agents "must" change Injector seals at every Tappet clearance check Interval. Apparently they say this is a documented procedure since Toyota advise to effect the tappet clearance check, the Injectors "must" be removed, and the seals then replaced.
I am not sure exactly when this requirement entered into the normal procedural documentation and process. Comment Please?
In Australia, the Tappet clearance check is at every 40,000 KLM, as opposed to NZ which is every 45,000 kLM.
I would imagine then that since the SIlver plated washers replaced raw copper, with a part number change, from 11176-30011 from the superseded 11176-3010, and have been in use since Early 2008,
Then if you find copper washers on your injectors in these later years, then it is an indicative sign that these have not been replaced according to Toyota noted procedures they refer to, or that they have been replaced with inferior superseded Unplated silver finish inventory?
In this case if you have had an engine problem or failure, and it is related to an Injector leak, like the Oil pickup clogging issue, and it appears your seals have not been changed, (colour being one indicator) then it stands to reason your vehicle was may not have been serviced according to what Toyota state is their standard service procedure. If so, and if was performed by an authorised service agent, you may have a claim back to the service agent according to this stated position on a potentially very expensive problem.
I would value feedback from Owners & service agents in respect to their opinion on this stated position, and as the wether they feel this is correct, and that These Toyota requirements are valid.
Looking at the current service procedures for tappet clearance checks, it does specify seal replacement. Have Toyota made this clear enough? I would ask people to comment.
