    Default oil catch install MI16

    Hi All,

    Hoping I can get some help with location/installation for a oil catch can to remove the oil reticulation systems which clogs up the intake. Would like info on physical location people have installed them and also the hoses/plumbing arrangement.

    Also after any recommendations of off the shelf oil catch cans which suit the MI16 or advice from others who have done it.

    Thanks,
    Geoff

    The best solution is to run a hose out of the cam cover and dump it on to the road EH Holden style.

    You can add a catch can behind the LH headlight if you like, but most importantly don't suck anything back into the inlet

    Can't dump the return oil line to fresh air as used as a Tarmac Rally car, won't pass scruitineering.

    What about running the oil return line that goes back to the air intake into a ventilated catch can and blocking up the air intake line?

    I'd be looking at proflow, they have a few quite good looking tanks.
    for CAMS I think it has to be 2L.

    This pic may explain it better. Put a tee in hose #6, the outlet of which goes to your 2L catch tank. Remove the hoses between the filler cap, TB and the AFM hose. Use rubber caps of the appropriate size & hose clamps to bung them. Rare Spare, Supercheap etc. sell them. You still need the hose between the AFM and the idle speed motor.

    The catch tank will still vent to fresh air, as they all do.

    Keep in mind that the hoses you modify/remove are rare and no longer available. Preferably, find a new hose to replace #6.

    Any idea what catch can you are installing? I'm looking at buying one myself and I may have settled on a Misimoto 2-port compact oil catch can. Has proper baffling and a 50 micron filter to condense any vapours, as well as diverters so that the oil vapour doesn't just go in one port and straight out the other. Looks pretty good, thoughts or other options?

    To re-iterate, if you're installing a catch can that will have to pass CAMS scrutineering, it must be minimum 2L if any part of it is vented to atmosphere.
    I like the look of this Catch Can 2L w/Drain Tap & Breather Natural, but they have a few options.

    I'm in the process of installing ITBs so I've been looking into this. I didn't know about the CAMS capacity requirement though, so thanks for that!

    Might pick one of these up with a barbed fitting and blank off the other inlet.

    I also just looked at the CAMS requirements - and yup, 2L for a sealed unit. HOWEVER (!), if you install a sealed (i.e - non-vented) unit and plumb it into existing pipework, you're all good and the catch can can be much smaller.

    Peter T - do you think the attached works as a sealed system (without the oil catch can air vent as per the pic)? Seems to make sense tapping off before the return to the intake and TB and then returning clean air to the intake & TB.....thoughts?

    A big part of the point is that you no longer recycle dirty air into the intake.

    I agree, the whole point is to avoid putting oil or oil vapour in the inlet manifold. I can't see how that solution in the picture is any better than the standard system. Just run a 2L catch tank, vented to atmosphere.
