Hi guys, Just wondering if anyone could give me a little info on opening up the breathers on top of my tapper cover. I have been told to open them up would -10an be big enough as they already make the adapters. and does the catch can have to have a filter on it thanks -kj

if you externally vent the catch can its illegal in vic anyway. legal way is vent the catch can back to the turbo inlet or intercooler piping via a filter. I haven't opened mine up i just got some aeroflow fittings. cant remember what size but they have rb30 in the part # and are designed for the rocker cover. I'd doubt that fitting size is a huge issue unless you are running a bajillion psi and rw killawasp. I'm pretty sure mine are dash 10 adaptors and then dash 10 fittings. running rebuilt nissan t3 6psi 3" exhaust fresh engine and no holes cooler 150 kw atw.

yea car is running on 12psi atm probably jump it up to 14psi after this setup is sorted . Just wanting to put the -10an Aeroflow lines in from the stock 6mm holes or whatever they are. Also can you just block the hole up from where the from breather goes into the Intake manifold..Cheers for your help mate .

Anyone ???

Yeah, you can remove the PCV valve and block it up, I used a threaded bung.

Cheers mate !!!

I had a bit of blow by on a new engine until I fitted bigger breathers. I have not lost anything noticeable (basically none) for the last 5000kms when I went bigger. See below link. http://www.calaisturbo.com.au/showthread.php?t=278676

Head breather to catch can & catch can to intake before K&N air filer. Just had a 3 inch pipe fabricated with K&N air filter and a 3an pipe running off it.
