When we talk about Daihatsu YRV, we normally think of the K3-VET 4 cylinder engine, but actually there are a 3 cylinder engine model of YRV which using the EF-DET engine, the EF-VE engine is commonly use on Perodua Viva in Malaysia market, in engine gasket side, most of the gasket in EF-DET and EF-VE are interchangeable, but we found something special at the intake manifold area.
You can find the above photo are intake manifold which is dismantle from Daihatsu YRV, there are basically have 3 pieces of gasket attached on it, an intake manifold gasket with 3 holes, an intake manifold gasket #2, and a throttle body gasket which you can find the gasket at the below photo.
The interesting part is the so call intake manifold gasket #2, which for the YRV EF-DET engine, it seems like a piece of rubber which without any hole (as seen on above photo), it seems like the function is to seal off the hole on the manifold.
Unlike the Perodua Viva EF-VE engine, this piece of gasket (which can be seen at the photo below) is having the hole just like those normal type of rubber o-ring gasket.
