VVT seals

My VVT seals are weeping a little oil so I have bought some replacements, not genuine but from a reputable source.
They seem very hard when I'd have thought a more pliable rubber would offer a better, longer lasting seal.
There must be a reason for this - can anyone tell me?

These VVT O-ring seals sit there on top of the engine and bake in the engine bay. I have long wished that a supplier would make them from more durable materials, but that is simply not the case. I have tried OEM ones and aftermarket ones. Regardless of the source, they tend to last me a couple of years before they begin to weep oil. I am currently on my fourth pair....

Since they can leak air, it is a good idea to not ignore them. I have had great results with Ford parts and then sealing them to both the valve cover and solenoid with some Permatex Black. No oil weeping years later. Easy to remove if one is careful. Made a big difference in fuel trims. They start to admit air after only a few months in service.
