6.4L isn't the same?

 

[charonblk07]

Different layout to the pump in the 6.4L. Bolt holes line up but I had clearance issues with the chain tensioner and the backing plate is a different shape.

 

[pickupman66]

YIKES. I have an 2009 with 105,000 on it. I bought used with 73,000. I switched to Amsoil 5w20 3 changes back and yes, I have heard a faint tick.

I'm a Chrysler master tech (Level 3 in all areas) also a ford senior master and ASE Master tech with L1 and L2 certs. I do at least 1 Hemi a week for lifter failure on oilfield trucks.mileage isn't the killer its engine hours. Because of the extreme angle on the push rods and the way the engine is lubricated. (push rods get lubed last) idling the engine causes low oil volume, therefore lifter failure. just run good oil and don't idle it and you will never have another failure.

I got 10k on my Hemi. I already hear a tick on her, hear it Lou's ar start up. Weather been - 15 plus. I am know to idle so I will stop that more than I can. I do Idle to warm it up. I run Mopar synthetic since 5k before that was regular Mopar. Is my truck Ok?

Sorry bud but no one can honestly say how long your engine will last over the internet. Do all the required maintence and run good oil and idle it the least possible and theres a 99% chance you will be alright.

I think the tick is just a characteristic of the hemi. There are plenty of hemis out there with a ton of miles on them that tick but run fine. My buddy has a 300c with about 95k on it and it ticks but runs fine.

The Mopar oil is essentially Pennzoil conventional and Mopar synthetic I believe is Penzzoil Platinum. I ran Platinum for about 5k and it started ticking like crazy. Switched back to Pennzoil Conventional and it quieted it right up so that's what I've been running since. Pennzoil conventional has a much higher moly count than Platinum. No idea why but it does and hemis love moly.

Hmm who would of thought hemi like Dino oil. So should I just go back to the basic oil? Same on my 3.6lv6?

What's moly?

 

[Hemi395]

What's moly?

Moly is short for Molybdenum. Its an antiwear additive in most motor oils. How it works is it forms a sacrificial coating on the metal parts that helps prevent wear.

Pennzoil conventional has the highest moly count (270ppm) of just about any oil out there, regular or synthetic. The only oils that have more that I have found are Amsoil, Motul, and Redline. Pennzoil Platinum while a superior oil, only has ~60ppm of moly.

Check out this thread for more detailed info on moly and oil:

Its crazy long but it's got lots of good info.

 

[Moparman1303]

This might be the first motor where synthetic oil is not advised. I might just be switching back to conventional. Just usually I find results with synthetic in my climate where it's really cold.

 

[Hemi395]

You can use a synthetic in the Hemi provided it has a high moly content. The 0w20 oils which are synthetic seem to have more moly in them than their 5w20 counterparts. No idea why. A great example is Quakerstate 0w20 which has about as much moly as Pennzoil conventional. I might try that for my next oil change if I decide not to go with Redline.

 

[Moparman1303]

I run Mopar synthetic apparently only has a 60 molly? I might switch back to conventional Mopar oil has way higher molly. But this synthetic does seem to help in this very cold weather were having.

If Mopar synthetic is indeed Pennzoil Platinum, then yes it has 60 ppm of moly. And this is exactly why I switched back to Pennzoil conventional. As for the cold weather, any 5w20 conventional or synthetic should be OK as long as its not -30 or something. Thats when a good 0w20 would be best.

I started mine up the other day when it was 0 out and I had no lifter noise at startup with Pennzoil Conventional.

Ya we have hit over-30c which puts it at a weird area. So next oil change I'm going back. Mopar synthetic is Pennzoil platinum. How much moly is in Pennzoil ultra?

Sorry I'm talking about -30F... Ultra is around the same as Platinum if I remember correctly.

Thanks Mate. Pennzoil needs to add more molly to its synthetic.

Yessir they do! I'm not sure why they don't! Their synthetics are fantastic oils they just don't have much of the one additive that Hemi's need.

I'm not sold that the roller ceased causing the problem, maybe the lifter stopped lifting causing the roller to cease. I think that is what so many of us hear, the lifters sticking when they should be lifting and contracting smoothly. Watch how the MDS works, just another thing that can break something.

it's at the end of the video.
