Today let's take a look on the Toyota Levin 20V 4AGE engine manifold gasket, although some may say they have differentiate by black top rocker cover or silver top rocker or may call it as 4 throttles, basically their manifold gasket consider a bit special when compare to other Toyota engine.
Have a look on the top diagram on the engine manifold and look at the second photo for their 3 manifold gasket inside a gasket kit.
The exhaust manifold gasket still consider a normal metal type of gasket design, with the design very similar to the Toyota Levin 16V which only differentiate by both left end and right end hole position.
And for this intake manifold gasket, it seems like make by the thick fibre material with metal gasket sheet on it, due to its original thickness, if one is buying the paper type of gasket, may be they need to re-use the thick fibre body.
The another layer of the intake manifold have this type of design, I'm not really know what is the technical purpose at this area, but they have the gasket with rubber seal attached in the inner hole.
