Knocking at start up.

[Nathan Mathies]

I have a 2015 ram 1500 5.7 60k km.
Problem I am having is a knocking/ticking sound at cold start up, only lasts about 10-15 seconds or when I put it in drive if it doesn’t go away on its own... now the problem is is that it has only happened about 4 times in a 3 month time frame the truck is driven daily. I had it in the shop to check manifold bolts and all are good. It started after I switched oil filters. Due to them not having my usual Mobil 1 filter. I used a mopar filter instead.

In your opinion could it be my oil filter? (Drain valve) I will switch back to mobil 1 next oil change that is due right away. I was just wondering if anyone has any other reasons why it would do this sporadically and not evertime? Could it be Piston slap? And wouldn’t that happen every time I start it up?

Thanks.

What oil brand and weight are you using?

 

[Nathan Mathies]

Mobil 1 5w20

I had more mechanical noise on the Mopar oil filter than the M1 also but mine starts 1:45-2:00 minutes after morning startup. So I was leaning towards piston slap over oil starvation. Interestingly when I put the truck in Drive the noise goes away immediately.
I've never had 10-15 seconds of engine chatter on start up; if going back to the M1 doesn't fix it I would try a different oil.

Redline 5w30 is the best shot at killing hemi tick, nick at gotexhaust has the cheapest price we've seen, pair with a royal purple filter. It is science not hype, polyol ester/pao base oil with high moly.

Read the quieting hemi tick in my signature, the one that is red and blue. Sometimes an oil will leave protection behind, read this. Mobil 1 has moly, about 1/10 of what redline has. But we have not had great success with moly treatments, some success, but not like switching over to redline 5w30. Try some different things of you want, but we all have tried everything we can think of, for 6 years +. Redline 5w30 was the collective result.

It sounds like piston slap but it isn't, we all experienced and it sounds like a knock, but the over whelming damage has been to lifters and cam, thus it is lifter tick.

Solid information and solution suggestion for a 2015 with 60k miles in a cold climate. I would expect the RL 5-30 and Royal Purple filter to make a difference,,,over time as the oil cleans and plates. My POV, RL is Hemi oil.

What are you referring to in saying “it’s isn’t piston slap”? Correct me if I’m wrong but From what I understand “knocking” is much different from”ticking” . And piston slap is def more of a knock while the lifter issue or exhaust issue is considered the “hemi tick” and is described as a tapping or ticking ...

maybe if we had a video to hear we could see if it’s the lifters leaking down he’s referring to or another issue . But I hesitate to make definitive diagnosis’s which can make people go crazy thinking something is more of an issue than it actually is. .....

Easy solution would be change the filter to a Mobil1 filter now. No need to change oil and what would it cost you 13 bucks (so maybe 15 Canadian rubles) between filter & a half qt of oil to top off?

Listen to the video's in that thread created by h395 and the examples of hemi tick, again in my sig. I can tell you from my own experience I thought it was engine knock, I only call it hemi tick because that was the title handed down. It definitely isn't a tick, and again I haven't even heard of one piston issue since I've been here on the hemi's, but more cam'lifter issues then I can even count. Possible it is piston slap, I guess so, but more likely it is hemi tick. many examples on the youtube. The fact it happens mostly at start up would also tend to be lifters as opposed to piston slap. There is kind of two choices, easy to try a lubrication strategy proven by many members here to be effective, or take it to a mechanic. Had the lubrication hadn't worked so well, none of us would be suggesting it. But as it turns out, hearty oil formulas like Redline 5w30 and presumably some of their clone oils have the science in their formula to deal with this.

As my oil change gets closer my ol hemi gets noisier at start up. Get a quality oil change.

Same here, oddly enough. Even with PUP it seems.

Going to Redline in the near future.

Only reason I ask is because I have a “hollow knocking” while cold until operating temp.... dealer listened and diagnosed and explained it as piston slap and normal for the short piston skirts in these hemis . Then proceeded to show me a brand new truck warming up do the same thing ....

Furthermore I have looked up a few videos of various make trucks making the “piston slap” noise and it sounds as a hollow knocking ....

Don’t misconstrue me as being argumentative ... just trying to clarify for myself and or others interpretations of various hypotheses

I have an oil analysis in the works and if their is lifter issues then my oil should be indicative of that. So we shall see soon !

I never thought of you as argumentative, I appreciate the info. Maybe there is a third cause for hemi tick besides lifters and exhaust bolts.

There is something we call the moly plate, although we aren't exactly sure why this happens, only that it does happen, people that use redline engine's get quieter with use.

The first time I used it I thought I just wasted some money, over time my tick disappeared. h395's documented over years it took his engine 1700 miles before it went silent. The difference is most oils use vii's, those shear in use and leave the metal less protected.

Whereas esters are polar, PAO's are stable branched chain, and molybdenum plates with time heat and pressure, something present in hemi tick and all of those things are in redline's formula. It doesn't cost that much to try it once, it is a very high success rate. If you do try it, it can take up to 1700 miles to silent an engine, it can be immediate, or it can not quiet an engine, every engine seams to be different, the one common theme is the high success rate over other oils.

I use mobile 1 because my dealer stocks it, and it goes away immediately after an oil change but 5000ish miles later it’ll get chatty on cold start for a second, then longer and longer till I get new oil and gone again. My next car will be a 6.4 and expect the same

Read the disadvantages at bottom, that is why your engine is louder before an oil change. It is science not your imagination.

 

[Burla]

I just post what we have discovered at Ram Forum as a collective overtime so you can make informed choices. m1 is a great choice in oil, second most popular on the board behind PUP. When vii's shear, engines that are running on mineral oil have less protection and will get louder.

When I read Beast19 post I read it like he was looking for incite and information. There is no better place to look than right here. The knowledgeable people on this thread have talked about the "noise definition" issue many times. A rotating or hollow engine knock is not a hemi tick. A screeching/hiss at start up is not a Hemi tick. Injector click is not hemi tick. Respectfully, it has been well documented on this forum that Hemi tick is most often the lifter tapping the push rod. Some experience it on first start up and it goes away as the valve train fully lubricates. Others experience it constantly and have clearly found that selecting the oil that their Hemi likes best eliminates the tick. RL PUP etc. Over the last year, I have learned more about what noises our 5.7 and 6.4 Hemis make than I thought I would ever need to know. But the facts are, oil formulas are changing. Solid results using RL are predominate. My 03 5.7 with 230k miles is proof for the RL 10-40 formula. My turbo GN has never sounded better, now that it is on RL 5-30. Kawasaki twin V mule hated RL. Will only tolerate Amsoil. Burla and the others are right. Nailing down what we are hearing is critical to getting helpful information.
