I noticed a smell as we pulled into the drive yesterday and when I opened the hood there was a little smoke coming up from the back of the engine. It was running fine, no engine light or rough idling. I checked the fluids and everything looked ok. Any ideas what might be leaking back there? This car has been a trooper but I fear she’s almost done for. I’ve done ALOT of fixing her the last couple of years but at 220,000 I’m about to give up after this…
