Which Oil Line To Use In Hi Octane Catch Tank?

[xanavinismo]

Hi all,

I bought a Hi Octane Catch tank for an R34 GT-R, and just wanted to ask you guys which oil lines you recommend I should use to go to the breathers, like brands and where I can get from etc?

Cheers,

Glen

Being poor I used hightemp oil resistant etc rubber lines.with hose clips. Pressures are low.

I used Aeroflow 400 series rubber oil line with Aeroflow pushlock -10AN fittings on my GTS-T mainly because they don't draw much attention, look good in black and being a non-braided line (which really isn't necessary for a crankcase breather) the whole ordeal was fairly cheap, obviously the fittings are a little bit expensive, but if you're buying fittings anyway it doesn't really matter

EDIT: as to where i purchased my stuff, i got it from rocket industries in sydney, but you can find all the items on ebay and other online stores

Thanks for the reply guys, so with my Catch tank the fittings are threaded, so does that mean I have no choice but to use Aeroflow or Earls fittings etc?

Like I cant just use rubber hose and clamp?

Cheers,

Glen

Correct you will need fittings not just rubber/clamp. If you tried rubber/clamp on those threaded fittings it won't work very well. You need to work out what AN size they are, I think High Octane racing mention the sizes on the product description. As a side note, I know you can purchase a High Octane catch can without the threaded fittings, designed for rubber/clamps so not sure if you knew that was available or not.

The engine covers which have your PCV valves would then need to be changed to fittings also most likely, which you can weld on. The PCV valves correspond to AN-16 size from memory, any smaller would be a restriction.

Unless someone has tried fittings on the catch can and just clamped at the PCV valve side, I personally don't know how well braided line would sit on the standard PCV valve outlets. The way Jordy has his catch can setup would be the ideal way if you go down the route of fittings on the engine covers and catch can.
