http://forums.clubrsx.com/showthread.php?t=296791 for this link dont you need to put one of the gaskets on so it doesent leak???

 

You shouldn't. Because they are designed to make a seal inside the cylinder head, so you may not need to seal them further.

You can always add a sintered metal or steel washer gakset. Just make sure and use some anti-seize to make it easy to remove if you ever have to do so.

 

i did that do it yourself o2 sim it worked out really good 4 months and no check engine light i also didnt use a gasket or anykind of seal i just did what the thread told me to do
