Noise coming from passenger side of motor
 

Hey guys I'm new here and I have this rattling/slapping noise coming from the passenger side of the motor on my LDK swapped LNF. I have the updated timing chain tensioner and the revised upper timing guide bolt. I have no idea what this noise is coming from and it happens around 2000-3000RPMs. I will add a video on here in a little bit of the sound but if anyone knows anything of what it COULD be please comment or let me know! I've been trying to figure this issue out for months and cannot figure out what it is for the life of me and don't want to send it off to the mechanic and spend money I don't need to spend. Thank you in advanced everyone?

Never mind I guess the file is to large to upload 🙁 I’ll upload to YouTube and copy link here

Timing? How many miles has it been previously?

The motor has around 15k on it. Previous owner had it stored for about 1.5-2 years. Was told the tensioner could’ve gone bad in that time? I have taken my valve cover off and saw the chain was loose but no guides or anything looked bad but the tensioner didn’t look in the best shape. I ordered a new timing kit just in case it wasn’t just the tensioner.
