Do you all notice your 6.4 hemi clicking or ticking at idle. Especially noticeable in traffic or drive thrus? Or is my engine especially noisy?
Trying to get some up to date 2019-2023 feedback on how other 6.4 hemi engines sound.
Ive had my 2022 2500 tradesman since new. 16 miles new. Always clicked like a baseball card in a bicycle spoke when coasting down hill, and could hear the echo against the canyon walls. When in a parking lot, cold or after an hour drive its the same. I hear it click very uniformly about as fast as one can pronounce click click click click.
It sputters a little after revving like valve lash then back to the clicking. Very audible when you stick your head in the wheel well. It has 30,000 miles on it now, ive done every oil change by the book, myself with pup 0-40, mopar filter, even use a torque wrench at spec on the drain plug. Ive watched the oil pressures curiously since day one, always been 50 cold, 50 while above 2k rpm, 30 at hot idle. And i may have been a racecar mechanic for a bit.
Last oil change i noticed for the first time ever the clicking went away. For about 5 mins when the oil was cold, it was so quiet, it didnt sound like a sewing machine! Drove it 30 mins, listened in the parking lot and it was back to clicking loudly as usual.
Heres the video
Ive seen all the youtubes on the roller lifters being prone to failure and grinding the cam away slowly. But no one has said here is what my bad lifter sounds like BEFORE replacing the cam. I know you can pull the oil control valve and check for metals shavings from the cam. I guess im bound to do that soon.
Basically i dont know what a normal engine sounds like vs a slowly failing lifter.
Seen the exhaust leak videos, which dont quite resemble this and the headers are solidly bolted on the block, tho that doesnt mean they arent leaking some exhaust sound.
Do you guys recognize what im describing, do the hemis sound like this?
