    Iv been having problems and problems with this car, after finding out the oil pump is on its way out, I have been looking through the engine making sure its not done more damage, is this normal cam wear, the ca has done 91,000 miles.

    I can't say that looks normal. I think it should look very smooth with no wear marks. The best way to inspect the cam is by taking off the fuel pump and inspecting the cam follower at the same time. Admittedly, it's probably faster and easier to take the whole valve cover off to inspect the cam that way but the one part that is making the most contact is the cam follower lobe.

    I changed the cam follower about a month ago but being honest I never checked the fuel lobe. Thanks :)

    with a black valve cover aswell, not the earlier silver cover.
    later BUL's came with a revised follower and cam lobes were improved a lot , cam follower and cam lobe wear are much less likely with these engine s but not totally immune to it.
    It may be possible you have an early engine that still used the softer items, all cam lobes should be smooth, if you have scoring to the face of the lobe then you have a bigger problem somewhere .
    I'd be inclined to remove the valve cover and inspect everything and also check the cam follower, if that lobe with the scoring is the one that runs under the follower, then there's a very good chance that is where the scoring has come from as the hardened surface of the follower has worn through.

    Just looked at your pic again , if that view is through the oil filler cap then you most certainly need to be removing the cover to see what else is going on in there, that is the opposite end to the cam follow so the cam follower wont be the cause of that lobe damage.

    If it’s creamy then you may have air getting in somehow or your PCV is not recirculating right. That’s really my opinion. I have no scientific evidence to back it up
