What tools do I need to replace my valve cover gasket?


Combination wrench set 1/4 " to 1" and/or 6mm to 19mm box-end & open-end or deep-well and short socket sets same size as wrenches with a 3/8" and 1/2" drive sets, Torque wrench, soft-faced hammer ( plastic or rubber ). The proper torque for valve cover mounting bolts is 85 inch-pounds for 1994 and later years.
Remove crankcase ventilation tube and hose from valve cover, Remove wire loom clips, note the locations of the studs.
Remove accelerator cable, kick-down cable and cruise-control cable from the snap in clips on top of valve cover, disconnect them at the throttle body .
Remove the three bolts and the control cable bracket.
Remove the valve cover bolts and lift cover off. If cover is stuck use a soft-face mallet to tap on the cover to break it loose.
DO NOT PRY ON THE gasket flange.
Contact me if you futher help.

How do you remove the rear seats in a 1993 Toyota Previa?


hi

The rear seats have 1 x12mm or 13mm bolt securing it to the rear wheel arch.

Remove the cover over the bolt and unbolt the bolt 12mm or 13mm on the left and right side wheel arch

Then under each seat is a metal clip that holds the seats in place lift them up to unclip the seats, and then they can be removed.

cheers

    I ran low on gas in my 2004 toyota solara after filling it up i noticed that it lost power and would'nt go over 45 miles per hour....what do you think the proplem could be?


    There are always deposits inside the fuel tank. Usually, driving around with more than 1/4 tank slshes them around enough to keep them out of the fuel pump screen. But, when you run low on gas, the sediment gets sucked to the screen, and blocks your fuel flow. If the solara is built like most toyota cars, there will be an overhead access to the tank. This is located under the rear seat bottom. Remove the rear seat bottom by pulling up on the back of it first. then tilt the rear toward you and push the front of the seat about 1/4 inch backwards. This will disengage the front clips of the seat. there will be a little circular cover with 10 or 12 bolts under there. remove the bolts and lift the cover. Pull the assembly out. You have the fuel level and pump assembly in your hands. At the bottom is a little motor and a fine mesh screen. When clean, this screen is white. When dirty, its usually a brown-orange color. You can get this screen from autozone or advance.

    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.
