Lifter tick

[HEMIMANN]

@Hemi395 - what say you? Why is a larger filter with the same element media producing higher idle oil pressure on the EVIC?

Assuming the oil pressure sensor is somewhere in an oil galley downstream of the oil filter, is my initial deduction off? Could it be the pressure is higher in with the bigger filter because oil flow is higher, thereby the measured pressure restriction is higher? Would Royal Purple use identical pressure bypass relief valves in both filters (same range of pressure reliefs)?

When I worked for Mobil, the lube experts said we should expect to see lower idle oil pressure when using synthetic oils because the PAO's they used then had less flow resistance within viscosity grades. School bus operators were alarmed when their psi dropped to 5 from 15, and we were told this was normal. Seems to conflict with a supposed less restrictive oil filter?

Champ labs makes royal purple filters which also makes Mobil 1 filters.

Yeah I'm not sure what to think about that TBH. Assuming the larger filter flows better and it's not the bypass valve opening all the time in the smaller filter, I think it depends on where the oil pressure sensor is. If it's right after the filter, to my way of thinking it would be an increase in oil pressure because more oil volume is getting past the filter.

I'm not sure where the oil pressure sender is on our truck tho. I do know there's a couple snesors on my truck going in right above the oil filter. One I'm pretty sure one is the oil temp sensor but the other I'm not sure what it is....

Personally I don't remember seeing an idle oil pressure increase until I upped my idle to around 700rpm. Now at hot idle it's in the high 40s. But I honestly don't remember if I did that at the same time as the larger filter...

Our older trucks have a conventional gerotor oil pump. Do these have pressure relief valves akin to any hydraulic system? If so, then we have multiple pressure relief valves - the pump and the filter. I guess I'd have to spend some time analyzing the hydraulic circuit flow to understanding how component changes impact oil flow and pressure. The gerotor pump is a constant volume pump at a fixed rpm, and the circulation circuit is a fixed resistance - so how does changing only the filtration flow resistance affect system pressure, is the question.

My 2011 Ram has been ticking for 3 years at first I thought it was an exhaust leak so I canged the manifold gaskets. After fixing many broken bolts I still had a tick. Now I was thinking HEMI tick but I was off warranty and I didn’t have the money to fix it so I just drove it that way. Last year I started having issues with lag on acceleration, especially when cold. This scared me even more. Took it to dodge for diagnosing. Was told my computer was bad. 2k to change the computer and problem still there. Was told to take to a specialty electronic diagnostic centre in town. Another 2k and they kept the truck for a month. Last week I pulled the top end apart. Lifters are fine scoped the cam, no issues there either. Ok hit up the interwebs. Found a forum that suggested check coil packs and VVT sensor. Ok pull the intake manifold off again change the $25 sensor check coil packs. Yep coil pack springs rusted all up. Now truck has more power than it’s had in a couple years. Good… but still ticking.

Welcome to ram forum, try a lubrication strategy, most time it works, look at poll results random members. It is not hype, these two strategies involve the heavy use of extreme pressure additives and base oils, and hemi tick is an extreme pressure condition. EP additives often take a little time to work, so if you try it give them 500 miles before judging them. My truck took 500 miles to go silent on redline 5w30, been silent since for 10 years except a few situations that were explainable. You can try biotech just by getting a 15 ounce bottle and dumping it in as soon as you get it.

Ive been looking looking a good diagram that shows the oil flow circuit for these motors for years now. The best ones I've found show the flow for the MDS system which is only the top end. I really want to see how the complete circuit looks but I guess that's super secret classified info...

@Hemi395 - remember when we could get this stuff in the OEM Service Manual or Chilton's? Oy

I normally start my truck, 1800 miles with the remote start before I leave the house. Last Friday I started it after I opened the garage door and for about 3 seconds or so I noticed a loud lifter ticking.

I plan on having the oil changed this coming Friday, what I do not understand is why this is happening already on this brand new truck. Very frustrating and disappointing to know that my truck will have to go in the shop, get disassembled and have parts replaced......................this is soooooooooooo not right folks.

For the 2021 trucks they've added this language to the owner's manual.

ENGINE OIL SELECTION — GASOLINE ENGINE​

For best performance and maximum protection under all types of operating conditions, the manufacturer only recommends engine oils that are API Certified and meet the requirements of the manufacturer Material Standard MS-6395.

Note:
Hemi engines (5.7L) at times can tick right after startup and then quiet down after approximately 30 seconds. This is normal and will not harm the engine. This characteristic can be caused by short drive cycles. For example, if the vehicle is started then shut off after driving a short distance. Upon restarting, you may experience a ticking sound. Other causes could be if the vehicle is unused for an extended period of time, incorrect oil, extended oil changes or extended idling. If the engine continues to tick or if the Malfunction Indicator Light (MIL) comes on, see the nearest authorized dealer.

See, it's your fault and not theirs because they used low quality lifters that bleed down because of poor manufacturing. But now they have admitted in writing that using the incorrect oil, extended oil changes and extended idling can cause the lifter rattle and is normal and will not hurt he engine.

So if you don't drive it for awhile it can cause the lifter rattle on startup so the solution is to use it more often? Yes, but if you have to drive it more than a short drive or it will rattle. How short is a "short drive"? Who knows? Oh, okay so more use is better then? No, "extended idling" will make it rattle on startup. Exactly how much idle time is considered "extending idling"? Who knows? Oh, okay so driving it less is better? No, go back to the first question and start over.

So covering their butts I see...

I bought a 2021 Ram 1500 last May and it's been ticking since day one. Put 187k on my 2009 Ram all while ticking...go figure?

It's only the OEM lifters that have problems. I have yet to read or hear about quality aftermarket lifters bleeding down causing lifter rattle. Maybe RAM should start using Johnson Lifters. https://hotrodenginetech.com/gen-iii-hemi-lifter-tick-solved/

Hemi tick is a trademark of Dodge. I personally always use the factory Mopar oil filter. They sell the factory Mopar oil filters at O'Reilly's for cheap. I used Castrol GTX for a long time and my truck had Hemi tick. I switch to Pennzoil (Factory supported oil at time of truck making 2004) and the truck has never made any ticking noises since then. In my experiences as a tech for Dodge and GM, the heavy line guys changed camshaft's and lifters frequently, but this is not always the problem. All brands have issues. =]

I wonder if they told the Eco Diesel owners that fires were "normal" and "they all do that"
