I need a diagram of the exhaust system on a 1992 toyota previa, showing the oxygen sensors, I have replaced the sensor with 4 wires, I was told that there was another sensor with two wires, however the two wire sensor only occurs on 1995 models and up, there is supposed to be a 3 wire sensor for the 1992, where is that sensor located and how many wires does it have.... I am going to go to a junk yard to find it and want to make sure that I get the right one....is there any way to test an O2 sensor???

SOURCE: how many gallons of gasoline does a 1992 toyota previa hold?

The toyota previa uses a formed silicone gasket for the valve cover and the cover is held in place by metric shoulder bolts ( 10mm). The valve gasket leaks because you can't get enough preload on the bolts to re-seat the old gasket when it gets old and shrinks. The shoulder bolts only allow you to tighten the gasket enough to seat the shoulder on the bolt. If you continue to torque down the suspected bolts, you will snap the bolt off ( don't ask me how I know this ). You can either 1.)replace the old gasket with a new one or 2.) remove the existing bolts around the leak area and put in new metric bolts that do not have a shoulder. You may want to put in a small sleeve into the existing bolt hole but shorter than the thickness of the valve cover to account for the smaller diameter bolt. You can now torque down the bolt and get enough preload to seal the valve cover without removing the old gasket. Make sure you use a torque wrench ( in-lbs) or be very careful not to snap these small valve cover bolts.

Change the fuel filter,if this does not correct the problem,replace the fuel filter in the fuel tank.Have the timing belt checked to make sure it has not jumped a notch.

Why would you not go to the auto parts store,buy what you need,return home and install it yourself.

You must have lost your mind,if you think that a junk yard exhaust system is anything but rusted metal.
