I have a 2000 expedition xlt w/ a 4.6l v8. Since ive had it, ive had 2 spark plugs pop out and had to rethread them, I've always taking care of it and done a full oil change with Filter every 5000 miles. Ever since I've had it I think I can't remember for sure but it's had to ticking noise when it's running and one time when one of my coil got loose it made the ticking worse so I just figured that's what it was from but it sounds like it might be an oil problem even though it does burn oil so I put some oil seal in it or stop leak in it and I seem to run worse after that. But today I stopped on a hill and noticed my oil light was on and my oil pressure gauge went down like lol like it was off and as soon as I leveled out it went right back on and just to test it again to make sure I pulled my front two tires up on a small curb and as soon as I did the oil light came on and when I pulled off and went right off so I don't know if maybe my sensor or my pump I'm not sure but the ticking didn't get any louder the quieter when this was happening and it doesn't make my MIL light come on. It just went over a 180k miles. I put it on the OBD2 sensor in no pids came up either. Also I have the Forscan app I use and nothing seems to outrageous there except it says low pressure under the oil switch. But I don't know if that's different since that's the first time I've ever looked at it. any help or advice would be greatly appreciated
