Poll: How many Hemi owners actually experience the tick?

The only thing worse was a Cobra Chicken / aka Canada Goose,.
We used to have a couple of Canada Geese that always nested by our dugout in the spring,and nobody or other animals even went close to the north side of the dugout in the spring,even the coyotes and foxes gave them geese a wide birth

How often do you change the oil in YOUR cat?

I tried to do it at 100 hrs,
BTW the best one at home would clean up any gophers close to home, that survived the guns on my gun range.

If you do some research cop vehicles with the hemi have a pile of cam issues,due to the amount they idle.

our 6.4 trucks idle probly as much as cops. took photos of a couple we have with 5k on one and the other over 7k. cams werent dropping in piles

Surprised at this result, we should have done this one before. We are hoovering around 1/3 of all owners experience hemi tick, that is a freakishly high result.

you of all people should know that injecter click and leaking manifolds and many other noises are often mistaken for lifters. most folks on the forums arent seasoned mechanics with any ability to distinguish one noise from the other

If you do some research you'll see your experiences don't really apply. A couple trucks with 5,000 and 7,000 miles on them,is a pretty poor representation.
Common sense should tell you that idling a hemi isn't great for it's cam/lifter longevity,as the cam lobes and lifter roller get their lube from crank splash,and moving the cam farther from the crank / sticking a VVT oil passage under it that blocks alot of the crank splash,and dropping the idle rpm down to 550/600 rpm,isn't going to contribute to long cam/lifter life. But alas common sense seems to have gone by the wayside

Yes, police vehicles with the 5.7 Hemi engine are known to experience camshaft and lifter issues, particularly due to prolonged idle time and frequent hard acceleration. These issues are more prevalent in police vehicles compared to regular vehicles.

Here's why:

• Extended Idle Time:
  Police vehicles often spend a significant amount of time idling, which can lead to oil breakdown and reduced lubrication, contributing to camshaft and lifter wear.
• Frequent Hard Acceleration:
  Police use involves frequent hard acceleration, putting extra strain on the engine and potentially exacerbating existing wear issues.
• Oil Change Practices:
  While oil changes are based on mileage, some fleet operators may not adhere to the recommended engine hours-based oil change schedule, which can further contribute to premature failure.
• Specific Engine Design:
  Some theories suggest a lack of proper oiling to the needle bearings within the lifters, leading to their failure and subsequent camshaft issues.

In essence, the combination of prolonged idle time, hard acceleration, and potential oil change practices contributes to a higher risk of camshaft and lifter problems in police vehicles equipped with the 5.7 Hemi engine.

its 5k and 7k idle hours. but ya a 6.4 work truck isnt exactly a cop car. never the less i think its more than just idling that kills them or all our trucks would be dead

Watch this complete video,to educate yourself a bit on the hemi's oiling system,and it's shortfalls.Yes it's more then just idling,it's also p!ss poor quality parts,but idling is a big contributor to alot of the cam issues.
Tom Hoover is the famous engineer they brought out of retirement to help redesign the block in 08 for VVT,and he knew there'd be issues,and he spec'd a billet cam,which would take care of probably 99% of the cam issues,but he was over ruled by the bean counters,and the engines get a much cheaper cast core cam,that is a bit weak on hardening,and consequently doesn't have a great life expectancy.By the way Hoover should of been slapped upside the head for moving the cam farther from the crank and putting a VVT oil passage under it. He built an engine that has a valvetrain that's good to 8,000+ rpm,but not so good for the average daily driver vehicle that see's more time under 2,000 rpm then it does above it.

Tell me about it! As a 49+ year professional technician, owning my own shop.... this issue is really widespread. Add to this, the social media fueled "The computer threw a trouble code for my catalytic converter, so how much is a catalytic converter?" and it is dyed in the wool, so to speak. A thermostat malfunction can and will cause P0420/430, for example.

I recently did $13K of work on a 2002 RAM 1500 4.7L where I replaced the engine, exhaust manifolds, the catalytic converter, the radiator, water pump, fuel pump, A/C condenser& accumulator, overhauled the 45RFE automatic transmission with all new electronics and a shift kit, I fabricated new transmission cooling line flex hoses, replaced all the coils and spark plugs... and many other things to complete a very nice running truck.

Fast forward to a week after he got it back.. He called me in a panic stating that he had a lifter tick. I dropped what I was doing and drove to where he was (literally around the corner from me) and had me give a listen. It was the injector tick which was and is normal!

I gave the man a lot of leeway in that he had spent a fortune to fix this truck up in opposition of spending easily 4-5 time that much going in for a new or nearly new replacement truck. AND, he had to dip into his retirement monies to do it, so I respect the man's position.

As a final "goodie", he did call me shortly afterwards to tell me how well the truck runs, and praised my good work. THAT is a rare thing these days.

2010 5.7 bought at 80,000 sitting at 188,000 now. Had exhaust manifold ticks I fixed myself at 120,000 (lived with it from 100,000).
What I hear now is when in MDS or eco mode it ticks, so around town I just use trailer tow mode; disabling the MDS. Thus no ticking sound. Explanation for this ? I assume if the cam or lifter was failing it would be there all the time.

Coming up on 90k for my 18. 205º oil idle in gear 41psi. Idle neutral 43-44psi.

Manifolds have been done, no tick there. If started and ran briefly then shut down, it claps the rockers a few seconds on the next start up. Repeatable and avoidable. Idle after a partial warmup, piston slaps a little. I'm aware of the possibility of issues but not afraid or paranoid. It doesn't tick.

Coworker has a 2010 with over 200k and no engine issues yet. He's not good for maintenance.

I was going to upload a video of what my truck sounds like, but it's not working.
Oh well.
