It never fails. The service engine light came on, just as I went to get classified. EGR again. We tightened the HECK out of those bolts. Went for the 110-mile cruise, no codes. Still a clunk, though. Found the front cradle bolts were loose. Oops. Tightened those. Drove to my hotel. Sunday morning, drove from the hotel to the venue for the awards ceremony. Smoke poured from the engine compartment. No idea. After the ceremony, ran the engine in the lot for 10 minutes. No smoke, no codes, but found an EGR leak under the EGR tube, by the mount plate. Drove home, service engine light. I guess it needs a new gasket. Again. No smoking or other issues.
Going to check fluids after the engine cools. Maybe tomorrow.
