I have a 2000 rt with 200,000 miles on it. Well maintained in Texas, hot but no rust. Always had synthetic oil and good filters. No oil leaks, uses a quart every 6000 miles. I just replaced the entire front suspension and steering. Rear end is next. Transmission was rebuilt at 70,000 and is starting to drip a little at the bell housing. AC crapped out years ago.I am starting to get some small core plug leaks and should pull the motor to replace them all. How should I best decide if I should rebuild

 

Welcome to the forum.

What's your budget?

I'd probably leave well enough alone for now. Focus on the core plug leaks, you NEED to fix that. I'd hold off on a rebuild until you really need it.
