SOURCE: 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.

1992 Toyota previa fuel pump cutoff switch


This make and model doesn't have a fuel pump cut off switch, the switch is only activated by an impact of 3 G's or more on cars and trucks that do use the switch. Spray starting fluid into the air intake of the engine, if it doesn't start you do not have a fuel pressure problem. Lots of things can keep a car engine from starting, you never mention any tests for fuel pressure or spark or proper valve timing (cam drive belt broken or jumped)

I have a Toyota Previa AWD, a couple of months ago when I would shut the van off it would not start again at all. I would leave it sit for a couple of hours and it would fire right up. The problem is...


I would first try putting a small amount of starter fluid in the air cleaner when it refuses to start. If it starts then, it is likely low fuel pump pressure which can be caused by a clogged fuel filter, bad fuel pump, or a poor wiring connection to the pump.
