My Celica (ST185) has a vent to atmosphere bov currently and I would like to have it recirc, ideally with a standard item. Thing is, I don't know what the standard one looks like and can't seem to find one online to know what I'm looking for!

Can anyone tell me if the earlier 3S engines had a different one to the later model? My only experience of 3S bovs is on the MR2 and they are different....

Alternative I guess is to route the HKS back into the inlet? But then it won't look standard.
