Hello board,

Failed!
Car is 87 740 non turbo. Still starts and runs well.
250,000 miles
Original cat. O2 sensor about 90,000.
02 ranging between .2v and .6v, and responds to sudden vacuum leak,as well as blocked air passage.
Plugs and wires good.
No apparent vacuum leak(sprayed around with carb cleaner)(also vacuum guage
reads 20, with a very slight rapid movement of the needle.
I did note brown stuff leaking)(more like oozing) from end of radiator hoses. Temp guage registers normal. No oil in coolant, or oil filler cap. Thermostat and housing recently replaced.

I will appreciate any assistance.

Thanks
