Attention 617 diesel owners, inspect your cams!!

i just bought a 116.120, and have done lots of work to it, since i drive 190 miles daily, i thought it would be in my best interest to replace the timing chain and tentioner before it breaks between home and work. so i start that today, and when i am looking at the cams i notice that the lobes are worn down very badly, so i look closer, and the rockers have very deep grooves worn in them,i just did a valve adjustment last week, but didn't pay attention to that since i need the car on monday, i ran to the junkyard before they close, and found a replacement cam, rockers and bearing assemblies, basically entire valve train. this car cad over 250k on the odometer, but the cam looked new. mine has 156k currently. is there anything that could have caused this oil pressure is very good? was it a problem with early made cams and rockers and i possibly still had those installed? what should i expect to see different with the good cam? i will post some pictures when i finish
