The compressor and the oil filter drain-back are separate issues.

I had the oil filter issue twice, on two of the four mobil 1 filters I tried.
Never had the problem with (6) OEM MOPAR filters I have used.

The oil filter sound is usually more of a loud, but brief ticking.
The AC compressor is a terrible metal grind sound, also brief but much harsher sounding. I have only heard it once.
Kind of sounds like the first few times I tried to find 4-lo......

I had a vw that did the same thing. I would start with

Starter. So I hit send too soon. Good luck

I had an idler pulley go at 2,800 miles but that was because I went through deep mud. kind of did the same thing; slight squeal for 3 - 5 seconds then good for the rest of the day. This lasted a couple of weeks then it locked up and ate a belt.

Without AC on, without fan on, it still did it. Got near 30 and did it several times. It is an awful sound. Can't replicate it in front of anyone.

Have you turned the key to the first stop, waited for the lights to cycle, then started it up watching for the low-oil pressure lamp (red oilcan) to possible flash momentarily? That's a sure sign of a bad ADV on the oil filter.

You can swap the oil filter without doing a pan drain. You only lose whatever is in the filter.

Ill give it a try. Weather Is weird as hell here this week with highs in the upper 60's to low 70's. so I'll keep trying but it might not do it anyway until it gets cold again.

2008 JK in Little Rock, Arkansas - mine does this if the engine has sat without being run for a few days before I start it up - such as if my Jeep is parked at the airport while I am out of town for a few days. It's a grinding noise for less than a second on first start-up only - even if I immediately shut down & restart, it doesn't happen again. Never replicated under any other circumstance & doesn't seem to be temperature related for me (temperatures are pretty moderate most of the time here).

Doesn't happen all the time & has never seemed to cause a problem. Discussed with my dealer (on extended warranty) - they said to ignore it unless it worsens or causes a problem so I have.

Good luck.

I've got the lifetime warranty, so hopefully if anything bad, it'll be covered if in fact ends up to be my starter, hopefully it will happen while at home!

I use the gold box FRAM filters and in my experience, they have been the best at preventing oil drain back/grinding starts. They have large anti drainback valves.
