  1. The SRT-8 (6.1L and 6.4L V8)
    Just trying to gauge some interest in a possible class action law suit against Chrysler/Dodge/JEEP for premature lifter failure. This is my 4th set going into this engine and the lifter that fails is ALWAYS the same one. The funny thing is that almost everyone of my customers who have had the...
  2. The SRT-8 (6.1L and 6.4L V8)
    So I'm working on the cam/lifter replacement at this time on my 06 300C 6.1. This will be the 4th set of lifters (3rd set to fail) in 186k miles. Anyway, just removed the drivers side cyl head and it's, ONCE AGAIN, the #5 cyl lifter that has failed. However, this time the lifter has mushroomed...
  3. 300C, Magnum RT & Charger RT (5.7L V8)
    Sad news on the homefront. My fathers Charger R/T seems to have developed a lifter tick. It only has 28,000 miles on it and is the only brand new car he has ever owned. Its no longer under the Mopar MAX extended warranty. Has anyone else had a lifter tick? Kinda wondering what to expect as time...

    Given the huge number of OEM lifter failures, what is the lifter of choice for a new Hemi build?
  5. Newbie Check-In
    Hello everyone and Happy New Year, dealer has been throwing parts at it and keep telling me its fixed and I keep sending it back. replaced so far both frt motor mounts and trans mount, rf strut, road force balanced tires and check suspension. Im afraid it might be a the lifter roller bearing...
  6. Magnum General Discussion (2005 - 2008)
    Well, Bought the beast with (08 R/T) 195K and I'm averaging 15mpg HWY (65 to 75Mph) and 11 to 12 city. Plan on compression testing this weekend, just looking for other opinions to check on to see what I can do to get it back up to at least 20HWY. I do have a soft ticking, assuming it's...
  7. 300C, Magnum RT & Charger RT (5.7L V8)
    Hey all, recently had major work done to my charger. Had a cam shaft lifter failure. Looks like 2 whiped cam lobes and another 2 were on the way, so a total of 4 failed lifters. Did all new lifters, new 6.4 cam, oil pump, pick up tube, push rods, valve springs, some new valves, valve guide...
  8. General LX Discussion (1st Gen - 2005 to 2010)
    I have been searching for a clear answer to this for awhile now, do the 2006 6.1l HEMIs have the same lifter/valve issues that the 5.7l has. Recently my engine (just hit 110k) has been making a lot of noise that sounds like it is coming from the heads. It has always been quite noisy, but there...
  9. General LX Discussion (1st Gen - 2005 to 2010)
    Just got done putting a new cam and lifters in a 2010 5.7 and when I went to start it up it made a horrible ticking/knocking sound similar to this Ticking noise after cam install - YouTube it sounds like it's coming from the drivers side valvetrain. Hoping it's not a lifter as I just put new...
  10. Charger Discussion (1st Gen - 2006 to 2010)
    Hi everyone, I've been suspecting the seized lifter/munched cam issue in my 5.7, and after finally getting the head off, I'm unable to remove one of the lifters on cylinder 5. I can get it about a half inch out before it hits on something and gets stuck. I've rotated it around 360 degrees...
  11. Parts for Sale
    Hello! I'm looking for a set of non MDS lifter retainer yokes if anyone has some they can sell me. My Hy-lift Johnson lifters didn't come with them. Thank You!
  12. Want to Buy
    Got an 06 5.7 in a 300c. Am needing aftermarket cam (mds) compatible, all 4 lifter packs (mds) and 4 MDS solenoids. Have block and heads at machine shop because of damaged pistons, bent valves, scored cylinders (due to dropped intake valve seats) My son broke all 4 mds solenoids when...
  13. 300C, Magnum RT & Charger RT (5.7L V8)
    Engine updates in my 2006 300C (see sig. for detailed mods) have been working very well, until one of the new MDS lifters fell apart. This chewed up a lobe on the (used) Comp Cam XFI 260H. Now I need to replace lifters and cam again. I wish the 260H had power or torque down lower, but at mid...
  14. Challenger Discussion (2015 + )
    Hey Everyone, My 2015 Challenger has been making an odd noise for the last few months, I assumed it was something rattling but then I heard it at idle this morning. I uploaded the dashcam footage/audio, not sure if you can make out the noise in the video (it's pronounced around the 40-second...
