3k miles since lifter cam job

fadetoblack188 · Apr 29, 2024

3000 miles on the motor since replacing the cam and lifter.

Just noticed this slight tap walking up to the car ..

Sound normal?

Pretty sure it’s not there at operating temp after driving it down the block

Just confirmed drove it around the block and the noise is gone

Sounds good to me!

We should probably come up with a name for this type of situation, Hemi Phonophobia maybe. I'm always listening to my engine it seems. Always asking myself what did I just hear typically the noise goes away and I don't hear it any more.

Same thing when you feel your phone vibrate in your pocket, but it's not in your pocket.

I would call that tick-ish, likely a 1 on the hemi tick scale. Normally I wouldn't worry, but since you already replaced the cam, you might invest some times in the hemi lubrication threads. Since it is a dry situation, use the products that are built to address this wouldn't be a bad move? Oil soluble molybdenum dtc is what the industry uses for dry starts. Not mos2 which also can be used for dry starts effectively but has more risky unintended risks. research and consider putting an oil built for this or additive. Change your own oil for a while, cut open oil filters for a while, check for metal.

I do use redline 5 30. Though I’m not sure I trust cutting filters open for a bit. As I’m sure there could possible be contaminant circulating from the previous failed lifter and cam. I would assume for a few oil changes at least

Wondering if I just need to retorque my manifold bolts now that they have been through a few heat cycles

Especially after replacing the cam and lifters I hear every little sound . That’s why this tick concerns me. Though it does go away when warm. Hopefully it’s nothing or an exhaust leak

if you want to find out how bad that tick is then run something other then redline, if it stays the same maybe it is bolts, if it gets worse or better then you know it is lifters. what filter you run small size or large?

This is after he just did his cam / lifter job. So he has new lifters in.

Yeah, my wife thinks I've lost my mind. It's even rubbing off on her.

Brand new Mopar lifters and cam in. Not sure they would fail in 3000 miles

Large filter

Stranger things have happened. Bad part from the box is not unheard of. But his "tick" seems like a minor one.

fadetoblack188 · May 1, 2024

Thinking maybe just the manifold need to be retorqued

Some manifolds make the "tick", even without leaking. Heck, the long tube header "ticking" is awesome.

But yours sounds like a mechanical tick. My F150 5.3 tick was way louder than that for 12 years and 100k miles

Don't bother wasting money on new manifolds, take your old ones to a decent machine shop and get them resurfaced. I did that about 3 years ago and it solved the problem. It is only a matter of time for new manifolds to warp because the casting has internal stresses. Old manifolds, by virtue of the repeated thermal cycling, have essentially been stress releived. Resurfacing the old ones will solve the problem.

That's pretty quiet to my ears. It could've been a lifter finally pumping up all the way.

If you hear a ticking from the top of the motor, and not below, it's probably fuel injectors.

If I had a Hemi, I would never leave it idling. You guys have scared me!

I have been overseas when I was in the military and had to leave my phone at home. I still felt the ghost vibration on my left side like my phone vibrating. I read and it's a real phenomenon.

What is Phantom Vibration Syndrome?
