Question about Toyota MR2
This is not s small job and should not be attempted unless you have a very good knowledge on timing systems and such? Luckily this is a overhead cam system, once you have removed all air system and hoses you can unscrew cylinder rocker cover to reveal cam. You will have to take cam cover off from side of engine, then you will have to locate cam timing tensioner, scratch cam timing wheel or mark with nail varnish for exact position! Then undo bolt to remove wheel, you will need a wedge to remove this/them if dual (this is the most important thing to get precise) then slacken tensioner to release belt after which you should be able to systematically undo cam shim bolts and release cam shaft, (make sure you make note of assembly for brackets as major part of healthy engine! If you shim s look worn then Defo replace them . After replracing New cam shaft line up old wheel with the timing marks and then you will be ready to replace timing belt and lining up cam position then tighten up belt and replace cam cover and rocker cover, if when you try to turn engine over you hear tapping noise, turn off immediately and ask garage to set timing up for you but remember to inform them of your escapades for them to fix. If no tapping noise then it done and you deserve a big pat on the back. Good luck and hope this helps?
