What causes the needles to fail in the lifters? I know the lifters are the last in line for oil. I have disassembled a few of these now, half have lifter issues. What say the "experts"? Thanks in advance!
I acquired a 2012 5.7 Ram engine with a #5 intake lifter failure. Opon disassembly I found other cam lobes showing signs of wear witch leads me to think it is an oil issue I know from working in a G M shop when they switched from a semi synthetic to a full synthetic oil lifter issues seam to dissipate. Plus I think today's bulk oils are crap. And as far as maintenance most people do not adhere to regular schedule, if they were on a 3000 mile interval they would do it at 6000, 5k would be 10k, 7500 would be 15k.Good article. But, like you said, they give a cure, not a cause. I understand the tick, but, not the roller failure. Maybe just a lack of maintenance.
i bought the g3 lifters and not stock rollers. just to make sure i didnt break a 1200 cam and 800 dollar lifters or worse.
piece o mind vs pieces of engine.
i think it also has to do with machining and pushrod length to non adjustable rockers being a big factor. they have a window of acceptable tolerance which is or can be say off from on end of the block to the other.
g3 aftermarket lifters that are about 800 bucks a set. thye make the aftermarket aluminum blocks now for hhp.Turbofreek, what lifters did you use? Thank you Realwing for the article.

just make sure they are not the chinese lifters or they will cost you much more in a very short run time.Makes the new in box Mopar set I bought at Carlise for $100 the deal of a lifetime.
There factory new in Mopar box. We will see as I will be putting them to the test for a winter project.just make sure they are not the chinese lifters or they will cost you much more in a very short run time.
check the actual part number on the lifters. then cross reference them with ma mopar or others forums with the chinese lifter failuresThere factory new in Mopar box. We will see as I will be putting them to the test for a winter project.
tell them about hhp g3 line of aftermarket lifters. well crap i guess you cant cuz they are non vvt liftersI know the OEM lifters (new in the box) in '06 LOOKED like machined pieces of art and came out of Germany. Don't know where the OEMs come from now. However, we've had a late model patrol car down since early September because of what the parts manager called a "Galaxial back order" (lololol) on them. As of a few days ago, he still has no projections on when they'll receive the lifters, even with a special "patrol car down" notice in with Chrysler. The cam is ok in this car because we caught the squeak early. It just needs lifters. They've always gotten my cam/lifter warranty work out within a few days.

In the ones I've torn down, it appears the cam lobe starts to fail BEFORE the lifter, you can see metal flecks coming off the lobes. I believe the camshaft material is to blame, (soft) a new camshaft from chrysler is like 85 dollars, what does that tell ya?
