I'm curious to see if that'* solved your problem. GF'* intrepid does the same thing occasionally in all weather, but it'* not as defined of a sound, and unless you're a perfectionist like I, you wouldn't notice it lol. If so, I THINK I may have thrown a Fram ToughGuard on there. Time to go mopar... maybe lol.

All right... Let me just take a moment here to say no to Mopar and then direct you to my oil filter thread (bias?). Enjoy.

I changed the filter out several days ago and I haven't heard the problem since! (although it hasn't been quite as cold, either.) I'll post if it comes back though!

Radomir, that'* a sweet thread... bookmarked. Thanks.

Good to hear the Caddy is healthy again

Please follow the links in it and read the previous posts of some of the guys on there as well. That'll get you ÜBER filter knowledge.

Some bad news... Since it'* gotten cold out again today (below 20*) the noise has returned. :( I'm pretty bummed out about it.

I'm thinking it may be a good idea to send the oil in to get tested. Where'* that company that does this? I can't remember. Also, the oil smells a little 'off.' Almost like there is gas in it or something.
