Zayed, Remo,
Do you guys have any experience with timing checks on the M113?

On the 113.984 WIS says the used chain timing calls for 25 ATDC @ 2mm lift on the intake valve both sides of the V.

When I test this I am using my dial gauge onto the centre of the top of the rocker directly above the lifter, I'm doing this to remove lash from the lifter...Is this acceptable?

The readings I get are 31 ATDC both sides, which I would have thought if chain stretch was apparent there would have been noticeable difference in values between the two sides. (when I go direct onto the valve its about 35 ATDC)

Now what is interesting, when you install the cam locking plates you install the right hand first, then when installing the left hand you need to turn the cam sprocket anticlockwise some ~2-3 degrees to allow the locking plate to bolt down.(yes never turn anticlockwise)

Now assuming there is no chain stretch due to the fact the values are equal both sides, Is it more than likely the play is coming from guide rail and/or idler pully?.

Your thoughts?
