In the case of sub-5k mile cars I can see some collectors wanting to say "it even has the original sticky tape residue from the dealer delivery note" and leaving everything untouched, but for a car with 85k miles, replacing all the rubber/plastic just counts under "service history" IMHO, and is better than having it be driven with 25 year old fuel, oil and PS lines with the risk of fire.

I'm not suggesting that the original cam seals have any value for being original. Their only value is in the fact that they are working perfectly well. Perhaps the original seals have been replaced. But, painting the cam covers is not something I consider needed unless the paint is flaking off, bubbling, bad in some way. If the paint is fine, then I would just as soon it be left alone. Knowing how blasting contaminates the metal (and how Murphy messes with people who fix things that aren't broken), it just seems safer to leave it alone if it's not needed.

If I were looking to buy this car, and the seals were fine, then I would not want the owner to paint the cam covers if their paint was otherwise fine--even if he offered. My personal preference, of course.
