The IMS tube is not an oven and is the same heat as all the other oil in the engine so all this talk of burnt oil in the IMS tube does not make sense.

However, stale oil that gets into the tube and stays in there for longer periods could potentially be an issue if that oil does not circulate in a reasonable amount of time.

With the DOF installed I seems like there is a greater possibility of more oil getting into the tube and "circulating" so that it hopefully does not reach a degraded acidic stage.

To me this stale oil issue is a product of not driving the car enough, infrequent oil changes or both.

Like anything new, I suppose time will tell if there are any side effects, but intuitively, with a constant supply of filtered oil washing through the bearing with the DOF I would expect much better results than any kind of bearing replacement alone, and if its driven often enough there should never be any stale oil issues with the DOF.

I like this idea better than a bearing replacement as it solves the issue that causes the bearings to fail...lack of adequate lubrication with fresh lubricant and has the added benefit of keeping that bearing at a more consistent and cooler temperature as well, which should also extend its life.
