Oil consumption in the old '91 Integra seems to be increasing very rapidly.
- oil is now VERY evident -- carbon is now wet, and throttle plate sticks slightly before cleaning is performed;
- intake plenum obviously coated with oil inside;
- exhaust emits brief puff of smoke when transmission is shifted at very high revs (not visible to driver, but is visible to following car).
Funny though, the car just passed smog with wonderul numbers back in the spring, and it starts and runs as well as ever. But gas mileage has dropped by about 1 mpg in the past year:
2008: 29.79 mpg 2009: 29.91 mpg 2010: 28.75 mpg (June-to-Aug, each measured interval roughly 3,000 miles)Not good.
