ok i have been getting oil up my TB and spacer and i was told that it could be caused by the pcv screen being bad..i took my pcv valve out and there is no screen at all...i have a vortech upper with a ported truck lower..is there any way to "make" a screen. i looked at my old stock lower and it looks like maybe i could use some steel wool or something..even if i do make some type of screen to put in there,will it fix my problem??
