6.4 MDS annoying?

[Ramnewbie]

In theory you're right, however if it was strictly an MDS problem why are non MDS lifters and 5.7's in the 2500 with no MDS also wipeing cams. MDS maybe partly to blame but I'm thinking it's more of an oil or oil supply issue.

It does that too.

I have been searching the internet for a resource that explains the design and function of MDS. Have you found one?

I agree with you and I don't think MDS is a widespread problem. It does however needlessly complicate the valvetrain.
