Timing cannot be adjusted but the cam gear is partailly spring loaded on a VCT system. this is a serious problem if belt breaks. iirc there are not set timing marks on a VCT system so it's a matter of testing different cam settings untill you find the right one.
if the belt does not break and you are just changing the belt, i suggest making your own marks with white-out against a solid boject or using a ruler staright across the gears with the white out aswell. anything to serve as a reference for your timing marks.
Snap-on also sells a DOHC cam gear lock-tool so the timing does not slip. for $50cnd it is money weel spent. even if only used once on your focus, it will work on pretty much any belt driven DOHC engine aswell.
