As y'all have suggested, I also believe it is lifter noise... It only happens on cold starts (so far) and seems to go away after the engine warms up, do y'all reccomend I take it in to be checked out? I have had AFM disabled through my BB tune since I bought it at 20k miles (it now only has 76k miles) because I was hoping to avoid this issue, at least until a much higher mileage.

Do you have a warranty? If so, absolutely.

If you don't, just before your next oil change do a crankcase Seafoam treatment.

I've heard/read really good stuff about Kreen from Kano Labs, but it isn't as readily available as Seafoam.

Wish I did but I don't because its not 2018 anymore so that puts me past the 5 year powertrain warranty period, unfortunately.

tore into the left headlight again today it was still intermittent, cleaned up the relay contacts, replaced the bulb, then as I was putting it back together I noticed my power lead was arcing on the frame thru a butt connector so I double insulated it and put some electrical tape on the frame hopefully that solves my problem.

I had a little fun with some vinyl today. I blacked out the grille emblem and experimented with partially color matching the door handles. I also removed the rear GMC and the faded Flexfuel badge. I'm not sure if I like the handles or not.

I thought I was smelling burnt voice coil, but instead, I was smelling brake pad.

Now I need to take it apart and grease the slide pins and clean the hardware I guess and make sure everything is moving smoothly. Hopefully the pads are fine.
