Hemi Tick or exhaust manifold

[blabarre]

2011 ram 1500 Laramie 5.7 Hemi. 6 months ago, I had a broken exhaust manifold bolt. I got the manifold planed and installed new bolts and a felpro gaskets. Well a week ago I noticed a lifter/exhaust sound again only on cold starts that only lasts for a couple of seconds. Figured the manifold bolts had come loose. So I disassembled the manifold again, used some copper gasket in addition to the felpro gasket and retorqued everything in the proper sequence. Cranked it back up and sounds exactly the same as it did before disassembling. Manifold didn’t have any visible signs of cracks or holes. As far as oil- Using mobile 1 5w 20 annual protection and mobile 1 oil filter. Been around 9k since last oil change supposedly oil is good for 20k. I’ll try to include a video today of the sound. If the truck is still fairly warm it doesn’t make the chatter.

Regardless of whether this is it or not, I would put in heavier oil. Like 5W-30 in the winter & 10W-30 in the summer. With the cam/lifter issues these engines have, I also would not go that far on a oil change. Probably would do it more like 6-8,000. Do a Hemi Tick search. There have been several guys on here that have cured it with a certain brand of oil.

I'm curious why you cut down the manifold? I don't know if that was your issue, those surfaces were mated and not ticking when the truck was new, or when you bought it? And then you had bolts break, and then you treated one side of the situation. Usually only bolts need to be done right to stop this. Was it the bolts or was there some warping? Did you dry fit and see an issue, and then dry fit again to see if you fixed it? I will come back when you post video, sometimes we can get a good idea by listening, although sometimes both ticks can sound similar.

I would encourage you to read the hemi tick thread in my sig, over 50 people have replied to try the strategy of using an ester high moly oil. The testing has been going on 8 plus years, it would be better at this point just to trust me rather then read 30,000 pages in syn thread. Read moly basics as well. Hemi tick that is lifter tick is perpendicular forces out of whack, so it takes a little time for the science of extreme pressure additives to work. But, if this is lifter tick, you can expect something different in the sound if you use redline 5w30 and a high flow spun microglass filter, read my oil filter thread as well.

I will take a look at your other thread. It was the original manifolds. 6 Months ago I only had a leak on the passenger side and one bolt was broken. There was some warpage so I had a local machine show plane it down because I had read from others on this site that the bolts break because the headers warp and if you have them plane it, it should be almost a permanent fix. When I disassembled manifold on passenger side yesterday(which is where the sound is coming from) , the bolts were not broken thankfully, I was just removing thinking I had another broken bolt. Now it has me thinking I have an issue with lifters or something else. Loading a video soon. Hopefully you guys will be able to help diagnose from sound.

Sorry for the delay. Here’s the video

I'm like 99% sure that is exhaust leak.

makes good sense, thanks for replying on that.

Lifters......doesn't last long enough to be exhaust......not enough time for manifold to seal from heat & noise goes away in less than 5 seconds......plus you said you had no broken bolts & manifold surfaced.
How long had it sit before starting for video?

Just to be positive though check manifold to exhaust pipe on that side.

I checked manifold on other side. It had sat over night when I did this video this morning. Agree that it goes away quick. It won’t usually do it if it’s been warm and I crank it up. Only if it sits for like an hour or more.

one of mine was .08 warped dealer replace it so that side is good ! but now hear a little tick on other side now ! but had a lot of noise a injector was bad also hoping no lifters who knows guess a wait and see game sucks right !

 

[blabarre]

Just hope I’m not on the path to replacing a camshaft from stuck lifters! I know some people probably won’t care about the sound, but I’m the type of person that If something on my truck’s not right, I’ll worry about it till it gets right! It eats at me.

Sounds like a lifter to me. once it fills full of oil it quiets down.

That sounds like lifter bleed down if it only does after it sits.
You said you checked other manifold......did you check where it attaches to the y-pipe for leaks?
What oil filter you have on........could be bad check valve in filter letting lifters bleed down.
If no exhaust leaks & another oil filter does not solve....internal lifter bleed downis issue.

 

[blabarre]

I did check y pipe connection, doesn’t appear to be leaking. I added some copper sealant to it as well. Oil filter is Mobil 1. But I do have 9k miles on it. I was trying the annual protection deal with the oil filter and oil to try and get more miles between oil changes. Think I spent 70 dollars on the oil/filter. This problem only started a week ago.

Mobil1 is a good filter......oil is good also....I would try changing oil & filter with that many miles.
Even though it's suppose to be good for 20k.....I would never take that route.
If new oil & filter doesn't solve......lifters are going to be the issue.
Try 5W-30

The tick that eats camshafts is WARM idle tick, and the reason you aren't hearing warm idle tick is because you don't have lifter tick. There has been nearly 20 videos with audio in syn thread and other threads on the issue, plus untold number of people who had this but didn't capture a video. Furthermore there have been guys that have went through multiple used oil analysis and recorded what oils were helpful and what oils weren't helpful. I believe @Hemi395 has such a thread with audio so you can hear it. And when you kill the tick with lubrication, look at the uoa's that show the wear metal come down, as in the issue is fixed with adequate lubrication not just masked, that is the science of what was done here.

But even with all of that, no guarantee your cam wont fail, it's a hemi and that is a weak spot, but you can only do what you can do, the rest is in someone else's hand. If you still believe it is lifter tick, read the redline thread, at least 30 different people at Ram Forum killed their ticks, the base oils and additive package are vastly different then anything you will get from walmart on the oil shelf. Listen to some other hemi lifter tick vids, yours aint it. This is good news for you, as exhaust tick is harmless, just annoying.

 

[Burla]

Lifter tick you can hear a banging behind the tick, whereas exhaust tick has more of a quicker cadence with a whooshie sound behind it. This tick is similar to mine, lifter tick, you can hear the sewing machine sound behind that tick. Exhaust tick is almost exclusively when an engine is cold, as the engines warms metal moves and fills up those air voids. Listen past the ten second mark, I can't be more clear, that is lifter tick, and that isn't your tick. Good luck

You used Copper but not Copper gasket maker? I would look at gasket maker, this is one but there are others as well. Follow directions to a t, and let cure overnight. As your mani's get warm they push gaskets apart, but when they cool the metal gasket can leave gaps, this isn't gonna happen with gasket maker. Yes if you crushed the copper in theory that would be better than other metal gaskets, but still this product will be the most versatile. You can look to stove pipe gasket maker as well, I'd just look for the one with the hottest temp rating.

You will have to take manifold down and put ths on, it wont work if you spread around edge.

This stuff 95% ratings 4 or 5, mostly all 5's. I think this will fix it and your tick will be gone.

Yes not the Hemi tick but still think its lifters not pumped up......just goes away to quick for an exhaust leak.......more like oil pressure builds that pumps up lifters & noise is gone.

 

[blabarre]

I used copper gasket maker for flange to y pipe and on the felpro manifold gaskets as well to give a little extra assurance. That’s what has me baffled
