Klinking sound from engine

Post by CMcGowan »

Over the last 2 weeks I have been hearing this kinda of klinking sound from the engine when it's warmed up and usualy under load at low RPM and raising 1.5 K to around 3.5 K RPM. The sound is kinda like coins rattleing or something. I have heard this sound before on my old Jeep with the I6 and it was a common lifter noise for that type of enigne. I checked everything I could, oil level is fine, coolant is at level and good, brake fulid is fine, battery is supplying 13.8 under load, AC blowing cold, no stuck pullies, nothing.Thoughts ideas before I take it into the dealer?

It's the typical tick of a japanese motor.

Sounds like it might be knocking, carbon build up? Maybe try running it hard on the highway for a few miles, really open it up after putting some injector cleaner in.
God, grant me the serenity to accept the things I can not change,the courage to change the things I can, and the wisdom to know the difference.

I was thinking it was knocking but it wasn't the usual sound and one would think the computer would throw a CEL. I'm due for another tank of gas in a few days, I'll throw a tank of premium in with a bottle of cleaner and see what happens.
