Hello everyone
I have a 2016 Dodge Ram 1500 5.7 Hemi with a new high pitched tick noise.
I’ve searched the site and seen a lot Hemi tick discussions but not what I think I’m experiencing. I recently did a coolant flush on the Ram and I’m wondering what tick noise Ive noticed while doing the flush.
When starting the engine cold or warm it takes 40 to 60 seconds to start. It’s a higher pitched tick coming from the passenger side, higher front of engine seems to be at valve cover level.
I used a stethoscope and listen to all parts of the engine, block, heads, intake, even at the thermostat, and there is NO internal tick which I was super relieved about. I've never had an injector tick louder than the rest or one sided line this and I don’t know why it would start a minute in. I removed the top plastic engine cover to gain access and will put the stethoscope on each passenger side injector tomorrow if they could make such a tick / clicking noise.
I almost thought it had to do with the water pump and the coolant flush I was doing but I don’t know water pump could make that noise and it remains after the air was purged.
I have replaced the passenger side exhaust manifold bolts 12k miles ago and all are still intact.
The tick’s rhythm remains the same at idle and through RPM increases. I only hear the sound when hood is open. I've owned the truck since new. 80k miles, always kept up with oil changes, No engine codes.
After I tested with the stethoscope, I dumped a bottle of Red Line complete fuel system treatment on an empty tank and fill with premium fuel.
If you guys have any ideas or have dealt with an injector noises which I hoping this is, please let me know your thoughts.
If it is a bad injector, do you suggest replacing all of them or just the one you suspect is causing the noice? Use a Factory injector replacement or any aftermarket like Bosch better?
I have uploaded a Video of the tick / clicking to YouTube but I’m not sure I’m allows to post the link here? It does help explain the sound and location better than typing.
Thanks in advance
