The big line between O&T letters on the harmonic ballancer determines TDC,I believe Pointer seems ok to me.Looks like chain/rails/tightener replacement time.I wouldn`t like to take a chance on those parts with unknown history.

Ralph,I alligned the cam tower/cam washer marks several times(yes,a fracion of a mm there gives couple a degrees change on the crank ballancer),but it still read BTDC.

Thanks for the replies.
And if ,after the replacement of the abovemantioned parts,the the prescribed degrees ATDC-using the 2mm.method -are not reached(due to sprocket wear or head height),I shall correct it by the correct woodruff key...Right?And religiously observed OCI`s
