Hey I've been researching for a couple of days and cant find what I'm looking for. 91 crx Si with a stock d16a6. I removed the head to have it machined after the timing belt went out. When I started to put everything back together I found these little filters that I didn't notice when I was taking everything apart. I only found three of them. Can anyone tell me where they go and if there is only 3 or if I need to find more or if they even go to the car? Thanks in advance.
