Hello, I'm new here. I read the DIY article about the catchcan setup on the back side of the Honda B20 block. I have the Honda fittings about the holes, but they seem not to be aluminum - they look too heavy to be aluminum. Will there be a problem when the engine heats up end there is heat expansion - both the block and fittings? If they are different alloys? I attached a image of what I have from the local Honda dealer. Second question is about the washers - they really seem to be aluminum (very lightweight) - should I use them as is or there is need to apply some teflon tape?
