Okay yall, I need some help. I bought a 2000 intrepid (3.2 120,xxx miles looks rough but ran good) it had been sitting for a minute before I got it. After a few days of getting it and getting it road ready and some exhaust & brake work done, I decided to give it an oil change. I know i did something wrong here and not sure how to fix it or if I'm screwed. I put a nicish filter given from orielys and some cheap 5w30 in after the oil change, and now there is some tick/clacking sounds consistent with the rps but only at certain rpms. Starting up and idling there is absolutely nothing, little rev nothing. Once it gets to bout 2k it makes the sound upon hitting the gas but as it gradually idles back down there is not sound. Is this a lifter issue, or a rod knock? Please let me know if you want anymore info, can take a vid if necessary. Prior to this oil change there was no sounds, tick, knocks or anything.
