Another Himi Tick

[riden2low]

I have a 2018 Ram 1500 with 96000 miles on it and for a few months now I have had this engine tick but only when I start up in the mornings or after it has been sitting for a while. So far after searching, I think I have a broken manifold bolt and possible warped exhaust manifold. So, I wanting to know if it's worth the money to buy the BD manifold kit and be done with it?

If you remove them and sand the mating surfaces flat with a belt sander , this will let them seal tight.

Now that the manifolds have been heat cycled,they are done warping.

Or

You could visit a machine shop that can plane them flat for you . Again both have been through enough heat they will be good to go, long term.

Remflex 6022 are a great set of gaskets to use ,they will provide a very good seal.

As to the longevity of the b@d manifolds, several members have installed them,however I don’t think we have any long term feedback.

You may find more information by using the sites search function, in the upper right corner.

Either way you should expect two or three broken studs/bolts , welding a washer then nut to what’s left will help you remove them.

You should start soaking with penetrating oil or other elixir of your choice.

A couple of weeks ago I started noticing a "tick" when starting cold or after the truck had cooled down (2011 RAM 1500, 125000 mi). Initially I thought it might be a lifter needing to get pumped up so I check the oil level. Right where the level should be. Checked this forum and learned more than I wanted to know, particularly if it was an internal lifter/worn cam issue. I didn't think that was the issue as the noise abated after a minute of running.

A couple of days ago I got under the engine area and did a quick cursory check of the heat shields on both sides (though it was loudest on the drive side) and they seemed fine. May not be a manifold issue. Rats.

However, I got back under it yesterday to see if I could isolate the source of the noise. This time I did a more thorough examination of all corners of the driver side heat shield and discovered that the top rear heat corner was loose - I missed that the first time. The other three were intact. I removed the shield and sure enough, the top rear driver side bolt was broken flush at the manifold and not the head. At that point I knew I could remove it with vice grips. I set about removing the manifold, which took about another hour, cleaned up the head around the ports and ordered a set of the BD manifolds. They'll arrive tomorrow. Will do the pax side as well. I placed a carpenter's square across the face of the manifold and found that it was bowed outward about 1/8 inch end to end.

I really appreciate the extensive information found in this forum as it has saved me a lot of time and money. ( A week earlier, before I researched this issue, I had mentioned in passing the symptoms to a mechanic I know and he said he knew what the problem was, he'd done a lot of them - it needed a major tear-down of the engine to replace the lifters, cam, etc. Yeah, right. Glad I found the information about "the other" common cause of the Hemi Tick herein. That guy might have taken me to the cleaners had I decided not to investigate it further.)

A tick after sitting for a while/few days is normal on startup usually lasts 20 seconds or so the MDS lifters lose prime If it lasts longer it is most likely manifold leaks.

Good find!

Keep us posted on the outcome.

Have you guys tried to use 91 Octane fuel?? High Octane fuel eliminated my Ticking sound back in 2013, when I bought my Laramie 4x4…. Now 215,000 and going strong…. Food for thought…

Just a follow-up on the replacement of exhaust manifolds. The BD manifolds are better designed, ribbed where needed to prevent warping. All hardware needed was included - even the manifold to catalytic flange bolts and nuts. When I was removing the pax side, the counterpart to the driver side bolt that was broken easily sheared off (top rear) flush with the manifold so I was able to put the vice-grips to it and remove it. There was slight exhaust blow-by carbon on the old gasket at that point so the warping of the manifold was creating a loss of seal there though not yet audible. Clearly, the bolt would have broken not long from now. Ordering the complete set of manifolds was less expensive than buying each side separately. Took longer to complete than I expected as there's little room to work with using a long-handle torque wrench. I did not disconnect the steering assembly but did pull out the oil dipstick tube, which helped.
As for the price: Buy once, cry once.

I am not an expert it appears to me no one looks at the quality of oil or filters ? this creats a problem, Mopar oil is not a quality oil then the filters. By the time someone does research the tick has began, WIX filters are the best people can't afford to us a roll of toilet paper. When you do your reserach Amsoil is one of the best, do your research, I checked with RAM about the oil they said that Amsoil is much better than Mopar oil. My veiw is either take care of your vehicle or replace before 100,000 miles, your choice I just past 170,000.

My 2019 had 55,ooo miles & I replaced both manifolds ,with the BD manifolds . The OEM were both cracked , no bolts were broken . The BD set up is so much better made than the OEM , just hope they last !
