I'd put catch can higher up on the list not the last. I'd also not bother with Dawes valve without doing needle valve at the same time, you gotta take turbo control away from ECU.
Intercooler is probably cracked already and leaking, any dark patches spreading about the fins near the end tanks? Don't forget that glow plugs timer mod should be high on the list too.
The ridiculous post glow time Nissan has set (5 mins) leads to all sort of problems.
I only put the catch can last on the list because of importance really. I really doesn't matter when you do the catch can. I couldn't agree more about the dawes and needle valve, but you need to do the dawes before you do the needle valve. I'll edit my post to make it more understandable. If fitting both, install the two together and set the dawes before the needle valve.
The glow plug timer is something that does need to be done too. Something I need to do to my Patrol. Not to forget installing metallic tipped glow plugs too.
Boost and EGT gauge first, than catch can, than needle valve and Dawes valve together at the same time than the rest.
For catch can try Ebay or Western filters ==> crankcase breathers ,they supply a kit, catch can with all the goodies like hoses, fittings, hose clamps whatever.
e.g. --> Universal Provent kit 16 mm hoses
+ drain valve and hose kit personally I wouldn't get the drain valve with hose from them as it is a rubbish and overpriced though.
The stop/ball valve is available from Bunnings and clear hose too all for princely sum of $10 plus couple of hose clamps. Hose is 10 or 12 mm.
I got the replacement valve from "Industrial fittings" and I just sourced the catch can from them, rest I got from elsewhere.
On mine 2005 Di the inlet end on turbo hose is 16 mm so I flipped OEM hose around to point to the firewall (backwards) and than rejoined its 16 mm end with another 5/8 (16 mm) hose via additional barbed 5/8 joiner to reach the catch can where another 2 reducers are needed to convert from 1" (25 mm) outlet/inlet on the Provent (so a bit of 1" hose is also required) to 16mm so you can run the hose back to intake hose. You'll need to measure the size of the pipe on your truck.
