1771 Cugnot Steam Wagen
Went to the dealer with an issue months ago October and they replaced the rocker arm on the E300. They did a coolant flush and refill and noticed "oil" in the coolant. Head gasket? Honestly it's shown no issues of leaks. Again, I haven't done a test with dye. Most recently the cars been getting in high temperatures of the 90° 92° temperatures. Forgot to mention that's with the AC on coldest climate. Also, recently when it's at a complete downshift from a complete shift, it shifts into first gear and it "jolts" or "bucks". This seems only once in awhile. Thanks if anyone as an idea what these issues are. The ACs getting looked at on Wednesday along with the rest of the car. The AC blows out one side cold (passenger side) and driver side sometimes warm and sometimes moderately cold. Just wanna get an idea before Wednesday.
