Hi guys, doing a bit on my project, I've just noticed that there is a hole in the bottom of my idle control valve. It had some kind of crispy cracked sealant round the edge and over the hole I picked a loose bit of and found the hole, do I sealant back over it? Any help/advice is appreciated
Car is a 1997 wrx jdm

 

Can somebody with the same car have a look under their icv to see of there's a tiny 1mm hole or is it blocked,
