Suicide hose & catch can

[Cuppa]

@Cuppa
I'm interested in what reducers you will be using.
I've just had a play with some reducers / hoses I've come up with in our diesel hydraulic mechanics work shop.
One issue I'm slightly concerned about is the internal hose joiners greatly reduce the internal diameter of the hose . So when a joiner is inserted inside a 16mm hose, the hose gains a 11-12mm internal restriction. If that makes sense.
Now I don't know what pressure this works under or whether or not this will be of any hindrance.
I've got the reducing kit pictured below at home but the joiners internal passage is 10mm at most.

@Hodge Yep I saw that kit after I'd ordered my reducers. Probably the one I should have bought if I'd found it earlier.

I measured the ID of the connection to the air inlet hose & it was exactly the same as the ID of the joiners I have - (approx 11mm /12mm). The Provent is made to be used on a variety of motors,including bigger ones than ours with greater blow-by flow. As I understand it as long as any restriction is no less than the stock TD42 then we should be ok. I can't see any point in trying to fit 1" pipes as there will still be the 11mm/12mm restriction which Nissan use.
