Engine noise

[Lb445]

Hey all, I was wondering if anyone knew about this or experienced this. I have an intermittent issue where when I start my jeep, the engine makes this noise: and when I turn it off and back on the noise goes away. I also have a intermittent long crank. Thanks for your input.

Sounds like an exhaust leak or a sticky lifter. Probably a lifter since it goes away when you cycle the engine. Maybe a can of Marvel Mystery Oil.

Could be piston slap to. Can be a common noise.

Mine does this occasionally at startup, not quite as loud but its there and then goes away after aobut 10-15 seconds. I haven't noticed any issues, i though the lifter tick was common.
