So i have my recently purchased 91 renegade. Did the oil change with valvoline 10-30. Fram Extenda guard oil filter. and oddly enough i now hear a knocking sound in the engine area. No loss of power, oil pressure is normal. Seems to only be happening at idol speed. Nose lessens or goes away after fully warming up. This was not happening before the oil change

Lifters or valve clatter in both the 4 or 6 is not uncommon at startup.

Get a mechanics stethoscope and see if it's under the valve cover or timing chain cover.

All depends on age and condition
