Stock Bov > Aftermarket (rb20det)

[ebj]

(I did a search and could'nt find anything, maybe the actual topics if any are just abbreviated funny)

I've got a '92 import HCR32, with next to no modifications except for an aftermarket BOV of somekind, and an HKS Super Dragon Exhaust with a custom exhaust manifold. Its running rich, like 14.5Litre p/100km rich, from what i've read i should be doing mid 10s even 11s p/100km;

So i've decided to service all of the basics,

Oil Filter, Fuel Filter, Oxygen Sensor, Vacuum hoses, cleaning the MAF intake sensor(A bit sticky when cold), cleaning the pod and intercooler, Rocker Cover Gasket (a bit leaky), and some of the oil pump pressure lines etc. Spark Plugs, Engine/Diff/Gearbox Oil Change, Fuel Pump(mines just about had it), and attempting to find some decent coilpacks that are'nt half a wopper, and since Bosch dont make RB20DET ones, I dont know what to get.

Getting to the point, its armed with this BOV, which sounds awful ricey and i cant for life of me think how its a good thing to have. it appears to vent directly to atmosphere, which in my understanding is'nt a good thing because then the exhaust side oxygen sensor tis'nt picking up correc readings (Fuel/Air Ratio's and will in turn run the car over-rich?).

so would i not be better of returnng the system back to its original Stock Plum-Back BOV? or is there a system out there that will work even better than the stock setup thats not too expensive and silences the Air Bypass.
