Oil consumption in the old '91 Integra seems to be increasing very rapidly.
Throttle-body annual inspection & clean Aug14/10:
- 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)
