    Default

    valve clearance is checked and adjusted every 100,000 kms (meaning every time the timing belt is changed), A simple feeler gauge is used to measure thickness and then its written down on paper, calculate what shim thickness is required for what valve, buy them new or at a scrappie (kabariya) the shim thickness is printed on them with unerasable ink.

    Be sure that the lifters go into the same bores they came out of.

    as a check of it, see if air is being pushed out of the airfilter box at idle speed, if it is coughing air outwards you need a valve clearance job.

    Default Thanks!

    As We never checked Valve clearence or tappet clearence(if same term) then I will go toyota to get this job done as hope that they have all shim sizes available and hope that they will do a tidy job,

    further pls.,brief here that the valve clearene or tappet adjustment job will affect the performace in which way and if any valve is reported bad will it be a head job or it can be replaced during this work?
    we should be proud of safe driving.
