does the same breather mods apply to the eco as xe? the reason i ask is cos a mate has a 98 astr gsi and the thick hose from the rocker to the throttle body has collapsed and was wondering wether or not you could apply the mod to reduce the air going through the pipe and could minimise the effects of the pipe collapsing (it will be replaced anyway, it's on order) also does anyone have the part numbers for the breather mod that vx did to this setup? as this hose has collapsed it has caused a few problems, oil is blowing out from the bottom of the dipstick where it meets the cranck case and the rocker gasket is starting to leak, could the pipe collapsing cause this? the car has only done 36k and i wouldn't normally associate this problem with a car of this mileage.
