I've got a b6100 diesel that has low oil pressure after it warms up. The hotter, the lower the pressure. Ive heard of some type of fix related to camshaft/ plugs. can anybody give me an idea of a fix?

Low oil pressure in a warm engine can be an indicator of worn connecting rod or crank journals. As the oil warms up, if there is excessive wear in the bearings, the oil pressure will read low due to the increased lubrication space in the journal. Left un-attended, you will probably begin to develop rod knock.
I would guess you have already checked the oil filter. Always start with the simple stuff, and go from there.
There could be other reasons, but worn journals has been my experience. ....

There is a plug in the gear end of the cam. I've read where it has a tendency to fall out over time. You have to remove the front gear case to get to it. I've also seen worn oil pumps do the same thing.
As beagle said it could be the bearings. Is there any knocking sound? Kinda hard to tell on a diesel!
What weight oil are you running? You may want to use a straight 30w oil and see if that helps.
good luck
