Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Would you class your noise as a rattle or a knock?
You might have a lifter/hydraulic lash adjuster noise.
I have a had good success with "Lifter free" or "Nulon E10 or E20" for this sort of noise.
I have had noise in one engine of sisters after oil change, that the Nulon fixed.
Might save you from costly engine repair.
My question is do you think the noise you have is a mechanical knock, loud low frequency "knock" type noise, or a "ticking" type noise from valvetrain?
Was the noise there prior to the oil change?
The noise is there only at idle speed, and not while while driving at all?
Do you need any further help?
