A little new to the jeep world, had an oil light come on the other day and knocking noise from the engine. Immediately checked and oil level was good. Took it home and I had a restriction in the oil filter(looked to be the case). Gave it a full oil change and added some liqui moly oil treatment to help it out.

After the oil change it quieted down considerably and oil light went off. Seemed to be OK. A day later the noise returned along with check engine light and a slight flickering of the oil light. Lost power as well(maybe from the knock sensor?). Just wondering if anyone had some advice? 2007 4.7 135k

Maybe there’s more of whatever clogged the first filter. Since they’re cheap why not change it again? Maybe drop the pan and have a look if there’s crud or metal.
