MDS and Nolimitz

[DarkHorse8]

Don't let one video of information force you into a panic. First off, the amount of "I think"s, and "I believe"s in that video are proof that even that fella is making assumptions not based on pure evidence alone, but his opinion.

Chances are you're going to have other issues than lifter issues. If MDS alone concerns you that much and you have the money to do so, then opt for engine work to remove MDS components. If you want to disable MDS for much less money, buy the NoLimitz.

If we go looking for problems, we're going to find them. Don't let the topic of "lifter failure" make you believe you're going to have it.

Enjoy your Jeep. Drive it for fun, keep up on oil changes every 6months or 6k miles, listen to the manual, it'll last.

I’m not panicking. Just an enthusiastic using forums for what they were made for. I’ve owned many cars, trucks, and toys and meticulously maintain them all and equally use the hell out of them.

Correct in that disabling MDS will not cure the issue. I don’t think disabling it will cause issues either. Contrary to popular opinion, MDS activation does NOT reduce oiling to the lifters. During MDS activation they actually get more oil flow. Ideally, the MDS lifters would be replaced with non MDS and the solenoids replaced to allow full oil flow (MDS mode) all the time and MDS tuned out of the computer.

The real root issue is the height of the cam in the block. This results in push rods that are too near horizontal to allow excellent oil flow.

I’m getting UOA at each oil change to monitor wear metals and give advanced warning.

Baring that, I just drive it like I stole it (after allowing oil temps to reach 180, prior to that I drive like a grandma).

Very helpful post. Thank you. And good point about oil temps reaching operational temperature. Your logic about the height of the cam makes sense also.

Having a great dealership honestly makes the difference, Also always try and manipulate a way to network with the service mngr!! You would be shocked at how far that gets you
And a few bucks opens more doors then nothing at all.

Amen to that brother, really great dealerships like yours was are as rare as gold! Just look at the reviews for Jeep dealerships, most of them are pretty pathetic and one of the major reasons I bought my 25 FE out of state.
