So upon further investigation the noise does in fact quiet down at op temp, however it isn't completely gone. really praying for a broken bolt not slap or lifter issues.... dealer is dragging their feet....

I bought an 04 Ram 1500 5.7 Hemi. It was tapping. I scoped it and the tapping seemed to be all over the engine. I was told by many mechanics and forums that lifters are the problem. I went through all the work of removing the heads only to find out there was nothing wrong with the lifters. It was pushrods that get worn at one end because on a Hemi the pushrods work against the lifter at an angle instead of straight on like most engines. CHECK THE PUSHRODS BEFORE YOU PULL THE HEADS OFF. They were between 4/7 thousand shorter with a pointed end on the intake lifters. That mistake cost me over a $1,000. A new set of pushrods cost less than a hundred bucks and 4hrs labour installing them.Hey guys just looking for suggestions on what would cause a tapping noise at operating temp on a 2011 ram hemi sport. i just had the manifold bolts replaced, cold start its smooth as silk but by the time i get across town to grab coffee in the drive thru i hear a loud tapping from both sides of the engine but it goes away after driving a bit. Seems to happen more when at quarter full operating temp if that helps. i took a video of the noise from cold start to when the tapping starts which is about 5 mins idling but i shortened it. Any suggestions are appreciated! Could my manifolds be warped?
Thanks in advance!

Did yours tap at operating temp too?

My 16 6.4 is exactly as you describe. Has almost 50k now runs great. Dam nosey ass motors. We are just not used to it.my 14 5.7 is very quietMan, these trucks are noisy. I don't think I have motor issues, per se. But I've never owned a vehicle with such a noisy motor. The weird thing is it doesn't seem to be consistent. I've too noticed it being noisier right after an oil change. However, I think that is due to changing oil brands. The last oil change, I did not notice a change at all. I think that's because I stayed with the same oil (QSUD) that's been working well for me.
I have no ticking on startup (right now, have in the past). I do have a little tapping from time to time after it's warmed up. But nothing like in the videos posted.
I bought Lifetime Maxcare - so I guess I'm not gonna sweat it. Truck runs like a top, no CEL's and MPG's are good. I really need to stay off of the forum. It makes me paranoid and gives me projects lol.
Dealer said it needs a new Cam and Lifters . Absolutely blows my mind at only 11k miles.... they also don’t have a rental for me
Hi Cshaffer126,
Thank you very much for your follow-up, I'm glad to see that your dealer was indeed able to locate a rental for you. If it would be of interest, I'd be happy to escalate a case on your behalf to connect you with a case specialist who can serve as your advocate while your truck is in service. Simply follow up with me via PM to get the process started.

I appreciate the offer and will keep it in mind. It appears my dealer seems to be making a good effort to ensure it gets taken care of quickly. They overnighted some lifters from another dealer and expect to have it done next week. My concern will only begin if this doesn’t fix the problem!
Update as of today :
no ticking sound currently present,
dealer replaced cam and lifters( no apparent wear in cam but a few lifters had rough but not blown bearings) few small marks present on cam lobes indicating the beginning of uneven wear . I’d say this is inconclusive
dealer used pensoil platinum synthetic 5w20. I had mobile 1 synthetic 5w30 previously.
will report tomorrow morning if it makes a noise or not on cold start.
Is it possible that 5w30 is actually not all that great for these engines with MDS? Do we have conclusive evidence of it being better ?
