Hi guys,

As a part of my rebuild all the mods i do also require a shit load of custom work to make them all fit.

todays question ( ive searched and found nothing) is...

How have you guys overcome the issue of using a head oil drain kit ( spool one) with the waterlines which run behind the head...

Pics are me holding the lines up. you can see the space from the head ( 10mm bolt ) to the water line bracket .

the only way past it that i can think is either bend the lines which i know will f*k them up... or cut them and insert rubber hose in place around the drain kit... but im sure it will rub and overtime cut into the hose.. :(

i purchased a justjap heater hose kit ... do any of these hoses help my issue ?

any help is greatly appriciated as allways..

cheers guys.

Forget the head drain kit. Just drill out and relieve the existing internal drains. If the head drain kit does anything it acts as a breather for the sump and this function is better acheived by drilling and tapping a hole in the top of the sump and running a breather straight to a catch can - which is what I did to solve my oil out of the cam breathers problem (along with 2x 1mm restrictors on an RB30/25). Skim through the last few pages of this:

Drilling out the internal drains doesn't really do a lot unless you funnel the leading edge of the top side because half the hole is covered by the valve spring seat.

Yep that's what I meant by "relieve" the drains.

Does anyone know ? Or am i the first person with this issue?

You need to bend the lines out of the way and have them loosely sitting under the drain area rather than bolted to the head.

If you are worried about rubbing, put a slit down some fuel hose and cover the steel line where it touches. There is not a lot else you can do, that setup is designed for race applications and assumes you won't be using the standard crap back there

Is there a kit u can buy that replaces that junk i really dislike it so messy

Not that I know of.

It's just water and boost. You can run vacuum hose to replace the boost but the water line will probably need to be braid or similar as it will need to go into the turbos directly

Maybe they are not on the market yet. Their website hasn't got them listed. But its possible they are available just not online yet.

Ring Andrew and ask.

i have the same problem on my rb25det, i have been trying to think of a way around it.

does anyone know if the line has to be on a fall, as in letting the water flow down into the turbo? or is it ok to use just rubber hose and bend it around head drain kit. i have lewis engine drain kit.

please help.

      Sadly I can confirm if you are actually seeking to drift, you will quite easily spin up one wheel. Even if you're going in a straight line. I am not entirely sure of the metrics/terminology here but there's only a certain amount that the helical will actually spin both wheels. I've seen it on video with my own car where two lines of smoke switch over to just one after you really get in to it. Unlike with a clutch diff where you can keep your foot planted until the car regains grip, in my experience with the helical you want to be utilizing traction control allowing LIMITED slip or lifting (partially) when you start to spin up both tyres with a Nissan helical. Which makes them pretty sub optimal for drifting duty. That said... this is probably a helical on numbers alone. Just put the Kazz in

      Unlikely, as per Greg's post. This is not helical diff behaviour unless one wheel is up off the ground. Shimming what? You don't "shim" a mechanical LSD. Probably not in the sense that you have heard of people "shimming" a diff. And the process that Nissan f**kwits call "shimming" a diff involves super-preloading a VLSD cartridge against the side of the diff to create a friction/wear point (in a place that it wasn't supposed to have one) to make the sloppy, useless, viscous diff into a hybrid viscous/mech abortion. In case it isn't clear, I consider the process to be stupid. Nike.
