Mds and OEM cam lifters arent the issue, what the issue is = the hemi design. So be careful if you delete mds, many times this will actually cause an immediate issue. You can use oem if you want, or not whatever. Look at the lubrication strategies to may help avoid this in the future. There is very little you can do when the design fails to properly lubricate, but if you delete mds you can actually create a situation where there throws a code and even worse fails to lubricate the engine, it has to be done appropriately but even if you do that doesnt prevent future cam issues. High molybdenum, the correct kind, can help poorly lubricated parts. It creates a plating effect in combo with other beneficial additives this can stop hemi tick in trucks that have hemi tick on oils that do not have these features.
