Didn't think the pipes looked disguised with grease or rotten tbh.
Please play nicely. No one wants to listen/read a keyboard warriors rants....
Took my red mist glasses off and had a good rummage through the boot and guess what I found!

A wheelie bin?
For the belts with two sets of marks. The white marks are for engines where the lower idler roller is immediately above the crank pulley. For later engines with the lower roller slightly higher and offset towards the nearside, you would use the yellow marks. Usually the belts have double yellow crank marks and single yellow crank marks for cam sprockets 1 and 2, so for the later engines you would use the yellow marks and the remaining white marks for cams 3 and 4. There shouldn't be yellow marks for cams 3 and 4 on the belt, so it's important to observe the correct rotation when mounting the belt.
Usually the later engines have a lower idler pulley without eccentric adjustment. The earlier engines do have the eccentric adjustment for the lower idler pully. Given that Gates part number XS035453XS is being fitted then it should include a new non-eccentric idler roller and the required screw.
Regardless of the engine type or the backplate and tensioner and idlers that are fitted then all the belts have the same construction, length, tooth pitch and number of teeth. Just that old stock belts might not have any yellow marks.
In any event you don't need the marks on the belt and probably shouldn't rely on them. Rely on the timing gauge.
No worries at all You'll get it spot on, I'm sure.
Usually when I fit a V6 cambelt kit, I get it almost spot on by the first spin, sometimes needing just a couple of minor fractional corrections. But, fitting my own (on the project) last week, I ended up making small adjustments and rotating the engine about 8 times until I was truly happy with it.
No shame in that. Because you know when it's done, that it's set up ab-so-lutely cock-on
