Lifter vs exhaust tick?

[iboughtatahoe23]

Very slight. Above the engine it sounds normal. Below the engine on the pax side I hear a slight tick, but nowhere near the criteria for concern, and I've had a failed lifters due to bad lifter trays on my 2012 in the past so I know exactly what they sound like. Any manifold bolts missing their heads?

Yep missing drivers side rear.

fix that first for 40$ and it will narrow it down for you.

Noise kinda gets louder when in park. In drive it seems to fade a bit.
