Hi! My first post here! I've been getting great info from y'all and can use some feedback on an issue.

I'm having bottom end rattle noise at startup. Goes away after driving a while. I've checked for Flex Plate issues and all is well there. Stethoscope says it's up under the oil pan. My question really is about what I'd need to check/replace up under the pan if I decide to go in. Never done anything quite this big but I'm gaining confidence so, hey, I might give it a shot. I've read about the bearing set in there getting to rattling but I'm not the wiz at this stuff (yet lol!) and need to ask you guys what this might be and what's involved in fixing it.

I just changed my oil to T6 5W-40 with a WIX filter.

Then there's this question. If I do nothing, what are the chances it'll just be OK for another year or so?

Hopefully these links work!
