Terrible video dude. Make a better recording otherwise we are pissing in the dark.

[Lproof5]

There really ain’t much to see, it’s more the sound. Sounds like it’s coming from driver side front of engine.

Suggest opening the hood, take your phone slowly a circle around your engine to record noise over both sides front and back. Lots of different things that causing ticking in these. Location is the key thing to know for suggestions. We will watch for another one! Also year, mileage and any modifications if any.

I’m thinking it’s coming from the crank pulley?
Is this wobble normal?

That wobble does look significant. These crank pulleys are known to fail and separate at the rubber bonding holding the two pieces together.
I’d go ahead and replace then assess if the noise disappears. If it fails it will fly off and cause all sorts of damage in that area.

That is definitely moving more than in should.

Did you see the video with the tapping noise?

The tapping noise you are hearing is probably the evap solenoid ticking which is normal, remove the rear sc cover and the U shaped black hose with a electrical connector is the evap solenoid. Put your hand on it after start up and feel if the ticking matches the frequency. Nothing sounds abnormal in that video to me, DI engines are loud as are the valve train. Get that crank pulley replaced asap, might be a loose bolt on the pulley but more than likely it is failing at the bonded rubber. Fix it now or risk it destroying a bunch of other shit around it.

I already checked the EVAP it’s not coming from there. I ordered a pulley and hopefully can change it this weekend.

It’s not hard to replace, just put the car in service position using long bolts to hold the front end far enough out to get to the pulley bolts. Use a paint marker and make a mark on the old pulley and it’s position on the block, this way you can mark the new pulley using the old one and line up the one off centered bolt more easily.

I end up replacing it without pulling the bumper or service position. But I would never do it again that way.

Sounds like a major PITA that way, service position takes like 30mins. Did the noise go away after replacing the pulley?
And you a current or former Southern Eagle? Finished my last two years down there, don't miss the swamp at all lol.
