14 power wagon lifter failure

Post by unitedwagon » Mon Sep 10, 2018 10:03 pm

Hey guys. I just lost number 1 intake lifter at 104000 miles and it took the cam with it. If Ram refuses to fix and I repair it myself can anyone tell me if I can use the stock cam (replacement) with non MDS lifters? I've searched for hours and seem to get both yes and no answers

Thanks. Any idea why some say mds cam shouldn't be used ? Sounds like something to do with the special ramps on the lobes

Yes they do. The 6.4 cam for direct replacement is only $60.! The closest non mds, vvt truck cam I came up with is the 2500 and and up 5.7 vvt non mds. I've been told this cam is not as aggressive, but haven't been able to actually look at specs for the two

Just thinking, do the 3500 6.4 trucks have mds?

There is no such thing as an MDS cam, only VVT and non VVT.

Not to disagree, but there are. The lobe ramps on the mds cylinders are unique shape vs standard

You're right, sorry. You can use non MDS lifters with your stock cam. I know of a dealer doing HC lifter swaps into 6.4 cars and tuning with HPP. A non MDS OEM cam is less than $300 if you want a new cam. A custom ground non MDS cam is around $500 to $700. I would think a performance cam would add about $1K to your bill after tuning.

No prob! I just learned this recently. Yeah the hellcat lifters are what I'm looking at doing to my truck. The stock cam is so cheap it's what I'd like to use, and I love the way the truck ran. New of course since the bad lifter wiped it out.

I spoke with Sheridan a while back about building the 5.7 and cam swaps. I wanted low/mid torque and the owner said that unless you want high HP at mid/high RPM to stick with the stock cam, as he hasn’t seen anyone make something better than the stock cam for usual ‘truck use’. Good options for high RPM though. I would presume the 6.4 falls in line with that as well but that’s an assumption.

Just so I am clear you lost the #1 cylinder intake lifter which is a non MDS lifter correct?

Just got off the phone with RAM and they are going to repair the truck under warranty! A case I had opened last fall before the warranty expired seems to have saved me. I'm waiting for them to let me know if they're changing all the lifters, or only the failed units. Told them I want all lifters changed...I've seen before only replacing the failed units

Yeah I hear you, I've just had bad experiences with other brands when it comes to repairs like this. Hoping I don't have to fight with them about it...stay tuned

Finally getting the wagon back this week! Engine repaired, then onto new tires and brakes...it's always something. I've missed it, and need it for work
