Engine tick????

[1990gtvert]

Hey guys, quick question about my 07 GT I noticed this morning that I have a slight tick comeing from my engine it sounds more pronounced from the upper intake, the car still runs and drives fine I took it to auto x yesterday and drove it 90 miles home, no problems the car never saw red line and all my runs combined were about 9:38 seconds, i was looking online about the valve lash and tensioners I was wondering what you guys thought I’m hoping I’m just paranoid, if it is ticking though how much longer can I drive it, the car will get put away in November so I was going to send it to a shop then or do they just eventually develop this noise, when I rev the RPMs up a bit the noise stays constant it does not get faster or louder it stays the same, any info would help thanks currently it has 105,836 miles on it below is a video of the noise you can really hear it until you pop the hood

Could be a cam phaser going bad. They're notorious for ticking, and the sound would be coming from up close to the top of the engine if that was the case.
