Anyone give us direction on the timing marks on the cams for 2.8 V6?
The crank is easy but the cams not so much.
At least my old eyes can't see em.

Yeah, as Mark Rutherford said, you need the tool. There are no timing
marks; on the crank or the cams. If you are seeing a mark on the crank
pulley, it is unrelated to the timing belt job. The crank is held in
position by removing the crank position sensor, then threading in a
holding tool. The cams have tapered noses with no key-way. The pulleys are
held on with a really tight bolt. Also, the noses of the cams have an
asymmetric shape that keys into the tool. The pulleys are separated from
the cams and correct cam timing is reestablished during the process of
changing the belt. I really don't picture succeeding at this job without a
manual and a tool. Also, change the water pump and all of the idlers while
you are in that deep.
