2012 Dodge Ram 1500 HEMI Engine Knock in the U.S.
#11
I'd take that bet, because engines do not just knock when they are cold. If it is knocking, its doing it full time. Knock is caused by failing parts that are out of spec - worn rod bearings, loose rod bolts or bad wrist pins. A cold noise is not a knock - it is lifter noise, or sometimes just detonation. I'm sure you've got 20+ years of engine building to back up your thoughts, so lets hear them

The below is my HEMI with a KNOCKING sound, that happens on COLD STARTUP only, then goes away after the truck got warm. Eventually, after 2-3 months, it started to happen all the time. But initally, it was cold startup only.

LOL. Wrong. It is a knock. Search YouTube for hemi manifold bolts broken. You'll see it produces a tick, similar to valve noise.
As for my noise, the engine was taken apart and they found a piston was 3,000 of an inch too small for the bore.

This is manifold problems. A tick

.003? How does that happen? And out of curiosity, did they replace the whole engine or bore it .010?

IM with OJ.thats what the manifold sound like when the bolts break....one piston out? sounds like a BS story to me, you need a new engine, thats obviously a lemon.............
IF you ever ran a motor , like a detroit, with a spun bearing, then youd know what a knock is, your motor also sounds like one thats been bored once too many times.
