The compression is the same for all cylinders(150), but when I turned motor over, water came out of #1 cylinder only. Any idea?


Sounds like a head gasket leaking water in from the cooling system. Does it run OK? Any water in the oil on the dipstick and a mayonnaise type film on the oil filler cap?

How to remove egr valve on a 1993 toyota previa


That previa has a central engine, so all engine work requires you take out driver and or front passenger seat out.

1992 Toyota Previa van,Oil dripping onto exhaust manifold, replace head gasket? need a free manual!


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.

I need to know where the egr valve is located


EGR stands for EXHAUST GAS RECIRCULATION.

This is a loop back system between your exhaust manifold and the underside of your filter.

The EGR valve is located between the inlet (exhaust manifold) and the outlet (intake manifold).


About 8-12" below the air filter....toward the passenger side.


EGR carbon built up can be clean.

Check the soft membrane on the EGR valve and see is it crack/torn. If it's in good shape then you may reuse it.

The professional use a vacuum hand tool to determine the travel of the EGR.

There are carbon built up inside the EGR air passage tube too,


Make sure you give both a good cleaning.


The EGR base gasket MUST BE REPLACE!


Order one before you start the job.


Please post more info on the comment window.
