Changed the oil Saturday at odometer 355,000.
3.5 Qt high-mileage Valvoline synthetic mix and new Bosch Premium 3312 filter.
Sunday I noticed coolant leaking out of the upper radiator hose, so that got replaced.
The car’s been doing great lately. I actually suspect heat soaking with with the idiotic 5-hour idle session may have freed up some rings? Cleaned out some carbon? Polished some bearings?
Warped the freaking longblock? The engine just feels a little more responsive
