Lifter/cold start

Just picked up my 2019 R/T on Saturday. Nice car!! I am getting a loud lifter noise on morning starts, even in a warm garage. Goes away in about 5 seconds. No noise driving. I did a search and spoke to current owners with the 5.7 Hemi. Seems to be normal from oil drain back. How many of you are experiencing this? What corrected it , if anything? How about the SRT Oil Filter #503804 AA? Is that OK for a 5.7? I usually dump the oil in a new car at about 500 to 1,000 miles and will likely convert to Penzoil full synthetic or Mobil 1 5W 20. Did that quiet it for anyone?



Thanks in advance for your thoughts.

I would swap out the oil filter first. SRT filter should work but I just run Wix. I only experienced lifter noise on start-up once but the car was sitting for quite a while.

Thanks for your response. I do like Wix oil filters. I know they make some of the Napa higher end filters. The car has done it every day since I picked it up Saturday. Dealer Tech says normal. A friend of mine just bought an R/T, same thing with his.

Invariably when an engine is shut off some lifters are under pressure from the open valve and its spring. Over time this can force oil out of the lifter, essentially collapse it. Upon engine restart the zero lash mechanism is not able to do its job until oil flow reaches the lifter and more than just reaching the lifter forces out any air and replaces it with oil. Any air left in the lifter can still have the lifter noisy as air is quite compressible while oil not so much.


If the noise goes away in just a few seconds this is probably not any real reason for any concern.


Certainly unless forbidden by the owners manual I'm an advocate of early oil/filter services for a new engine. I would urge you to use the oil the factory recommends. If you have the choice between mineral oil and full synthetic oil my advice would be to go with the synthetic oil.



In the case this noise is a precursor to a more serious problem, and I don't believe it is, relax knowing you have the new car warranty which you can use to have this addressed should it advance to the point it needs addressing.

Thanks Rockster. I am going to dump the oil early and use the Penzoil synthetic that meets their specs. I already advised the dealer of the noise in case it turns out to be a problem. It does go away in about 5 seconds.

I use the Pennzoil Platinum full synthentic, not the Ultra that the 392s require, saves a buck or two, 5W20 with the Mopar 899 filter. The regular Platinum meets the FCA spec listed for the 5.7


No tick ever in my '17 R/T w/16k miles.

FWIW, when I had my '10 R/TC (new to 42k miles), I had occasional start up lifter noise/rattle.

Pennz Ultra was not on the market at the time, and I switched to Castrol Syntec and the SRT filter.

Start up lifter noise was virtually eliminated.

With my present '16 SP, I've been using the 0-40 Pennz Ultra and SRT filter (27k miles on the car now), and have never had the start up lifter noise. Not even one time.

YMMV, but this is my experience with my two Challengers.

My suggestion; its normal, turn up the radio. The engine particulary if that new there is simply no reason to skimp on oil or filters. price a new crate engine from Dodge and ask if the savings warrant the risk.

Yes; mine is a 392, but I have the dealer do the oil changes so the correct stuff goes in. For a few bucks I'll work OT.

It should not be giving you clattery stats every morning, that is not normal. Occasionally it's fine and is somewhat normal, however my car hardly ever does it. Question, do you pull the dipstiuck and check your oil level often?

Never skimped on oil or filters and have no plans to do so. I do my own oil changes and maintenance on the lift in my barn on all my cars in including the Viper and Z06. Not sure about turning the radio up as solving anything, but I agree that it's likely normal. Would be nice to quiet it down.
