The manifold gasket is the same as the plenum gasket. The manifold gasket is a barrier between the manifold and the engine block.
No.
It is on the underside of the intake manifold
You will need a intake manifold set and possibly a plenum gasket set.
yes it is
The plenum is the intake manifold.
Plenum is another name for the upper intake manifold.
Yes, they share the same gasket and bolts.
White smoke is coolant in the cylinders. Died and won't restart cause the spark plugs are shorted with coolant. If you keep trying to start it without fixing it you could bend a rod! Most likely it is a failed intake manifold gasket or intake plenum gasket or the intake plenum itself. Don't drive the car cause if it is the plenum leaking coolant into the engine it can fill a cylinder with coolant and do major damage when you try to start it. No way to know for sure which of the three it is without pulling the plenum. If you're pulling that you might as well change the intake manifold gasket too. Could be a bad head gasket
Upper intake manifold plenum leak/crack most likely. If its blowing out coolant then you probably have a bad head gasket.
The plenum is the upper part of the intake manifold.
The intake plenum on a V-6 or V-8 is bolted to the top of the intake manifold. It has the throttle body bolted to it. The throttle body houses the throttle plate and is located at the end of the tube that starts at the air filter housing. Sometimes the intake manifold on a 4 cylinder is referred to as a plenum. It works the same way and is found in the same manner. Look for the air filter housing, then follow the hose past the throttle body to the intake or plenum.
You have to remove the throttle body/air intake plenum to get to the rear plugs. I believe the plenum is supported with two or three stays which are hard to see. You will need a new gasket for the plenum/intake manifold interface.One post on Toyota Nation Forum says that it can be done without removing the plenum. I think he is skilled at beating the clock at a repair shop.
