Hey all,

I did a bit of a search but not exactly sure which terms to use so didn't find anything of much use.

I'm looking for something to protect all my vacuum/air-con/similar hoses from heat; I found over the weekend that a lot of my hoses on the exhaust side of the engine bay have gone hard and many are cracked. The ones on my boost controller solenoid in particular were completely shot and that is only about a year old. Short of using fire sleeve, what do people generally use to protect their hoses? Does the silver wrap from factory on the heater hoses actually do much, it doesn't look like it would be very effective?

Any suggestions would be well appreciated,

Cheers,

Martin.

I bought some silver reflective stuff off Go Gear, which will work fine for anything not too close to the turbo. But it is a wrap rather than a sleeve.

I've got some of that stuff lying around, I used it as an outside layer on heatshields, but it seems an arduous task wrapping little vacuum hoses with it... Was hoping someone may have found something maybe like conduit that could quite easily go around the hoses.

A lot of these hoses are quite close to the turbo as well, I'd like to reroute as many as I can to keep them as far away as possible, but some of them it's just unavoidable, eg. wastegate lines, boost controller lines, etc. etc.

the problem with any of those heat wraps, conduits, shields, what ever is the heat from your turbo and dump etc is extreme and still melts the plastic from the wire over time..

without needing to drill any holes I was able reroute all the wires that ran down that side, out into the guard, up near the windscreen ( runs between inner guard and guard liner ) and back into the engine bay near the headlight,..

Problem solved :thumbsup:

Yeh works for wires, but not the vacuum hoses or heater lines. The heat from my turbo is destroying all the rubber hoses on that side, and in the instance of the wastegate/boost controller lines, that could cause some serious problems if I don't catch them in time...

one of the sites i worked at up north used to cut the factory sleeving off injector harnesses on new engines before fitment and used a fibreglass sleeve simular to the red sleeving you see on peoples oil drains. was about half inch diamter and thinner than the red stuff but was effective. tooks years or so of contant 24/7 operations to make the wires hard and brittle compared to factory. i have put aside 10m or so as i rewire mine in the next month or so. i have it in black and yellow. will have a look for part number and price if your keen. :thumbsup:

would heat wrap work?

Possibly, but again it sort of seems a bit more effort than it's worth. I'm talking about 4-6mm hoses, so to wrap all of these with something like exhaust wrap (I assume that's what you mean by heat wrap?) or heat reflective tape would be quite a job.

I did find these two products on the website that Paul posted:

http://www.heatshieldproducts.com/productdetail/heat-shield-sleeves/hp-hose-sleeve/59/44

Those look like what I was hoping for, don't suppose anyone has any experience with these or similar products??

hey mate ive got my ass hanging at work so havent been able to upload photos. internal diamter is 10mm and costs $4 a metre. will try get photo or 2 up tonight

You can get this stuff? I need some for oil/water lines and boost lines around the turbo.. $4/m is quite acceptable!

oh the farken issues ive had trying to get these photos uploaded, if it wasnt the camera it was the computer usb then the computer in general etc.

the $4 a metre applies to the yellow one you see here. i havent found the part number of the black one yet but im guessing it will be simular. i also need to find out if it can be sold in smaller boxes but i think it can be bought by the cm

We've used a product called fire sleeve with good success.

red stuff? if so that stuff is the goods :thumbsup: but ive never seen it in a size that is practical for vacumn lines. but perfect for turbo oil lines etc :thumbsup:

Yeh that's it. Fire sleeve is also hugely expensive, I couldn't afford enough of it to cover everything that needs to be covered.

Thanks a lot for that Trev, I appreciate it thumbsup.gif Do you know what temperature that stuff is rated to??

      Fark what are the changes of that snapping like that, clean. Nek minnit, custom radiator goes in, with built in oil cooler like those discontinued PWR ones from yesterdeacades ago

      7 Speed Auto transmission fluid change (Skyline, Q50, Q60, Fuga, Q70, A62 Titan and probably heaps of others including Navara...)

      By Duncan · Posted

      I thought I'd do a write up on an auto transmission fluid change for a the nissan 7 speed Automatic. At some stage the genius engineers decided that the fluid in the trans was "for the life of the transmission", (which seems kind of self supporting to me) and removed the dip stick and fill tube (funnily enough there is still a casting for it). Anyway, for this job you do need 2 specialist tools in addition to regular hand tools, jack and good chassis stands. You need a way to pump fluid up to the transmission; I got one of these but there are plenty of other options: https://www.ebay.com.au/itm/364584087070 Don't trust the generic listing though, it does not come with the required adapter for the Nissan 7 Speed. You need one of these, can't do the job without it: https://navarapart.com.au/product/genuine-nissan-patrol-y62-d23-np300-navara-re7-dipstick-fill-connector1 You need a heap of compatible transmission oil. Could be Nissan, could be anything else rated for Nissan Matic S. You need at least 10 litres, I had 15 to give it a better flush... Also, you need some biiig oil catch trays, at least one of these, or bigger if possible (volume was fine, size was very marginal): https://autobarn.com.au/ab/Autobarn-Category/Tools-%26-Garage/Specialty-Tools/Oil-Service/Garage-Tough-Oil-Drain-Pan-Black-16L---GT1068/p/TO03191 Finally, a measuring jug is very useful if your pump does not have volumes marked on it, I got a 6l one: https://www.repco.com.au/oils-fluids/fluid-accessories/measuring-jugs/penrite-measuring-jug-6l-pmj006/p/A5322648 Oh, and gloves.....this stuff is horrible (not as bad as diff oil, but getting there) ....First, jack up your car.....

      So I mentioned the apprentice, @LachyK helped take the bonnet off. We just undid the nuts on the hinges and unclipped the gas struts, then pulled the bonnet back a little as the front was catching on the front bar.  I had a good look at everything today and have removed the rams, repaired/reset the hinges and bolted it back together like it never happened. I'll do a separate write up on the repair, and I also removed the poppers from the Fuga today too to save grief down the road.....as said above it is at least $5k to repair retail. I'm also happier about my ability to prepare a race car, and less happy about Nis-nault's engineering (I can hear @GTSBoy sAfrican Americaning) because the top hose of the radiator didn't slip off.......it snapped clean off. By practice I put the hose clamp hard up against the flare on a neck to make it least likely to ever move (thanks @Neil!). I guess that puts a little more pressure on the end of the pipe as it is further away from the rad, but still, that is pretty shit. I've put it back on for now as there was a fair bit of neck still there, but obviously there is no lip on the neck any more so I don't think I'll track it again until I have a new rad. Speaking of which....more research required. It looks like Koyo makes a standard size radiator in ally which I'll grab in the meantime, but I really want something thicker so might have to go custom in the medium term (ouch) Coolant still needs a refill and I have the pressure tester on it over night, but other than a wash down of the engine bay it seems alright. And @MBS206 noted something noisy on the front of the engine and I think I agree....time for a new accessory belt and tensioners I think.

      our good friends at nismo make a diff for it, I have one (and a spare housing to put the centre in) on the way. https://www.nismo.co.jp/products/web_catalogue/lsd/mechanical_lsd_v37.html AMS also make a helical one, but I prefer mechanical for track use in 2wd (I do run a quaife in the front, but not rear of the R32)

      R33 persistent issues. P/steering and lag/misfire

      By GTSBoy · Posted

      What are we supposed to be seeing in the photo of the steering angle sensor? The outer housing doesn't turn, right? All the action is on the inside. The real test here is whether or not your car has had the steering put back together by a butcher. When the steering is centred (and we're not caring about the wheel too much here, we're talking about the front wheels, parallel, facing front) then you should have an absolutely even number of turns from centre to left lock and centre to right lock. If there is any difference at all then perhaps the thing has been put back together wrongly, either the steering wheel put on one spline (or more!) off, and the alignment bodged to straighteb the wheel, or the opposite where something silly was done underneath and the wheel put back on crooked to compensate. Nut there isn't actually much evidence that you have such a problem anyway. It is something you can easily measure and test for to find out though. My money is still on the HICAS CU not driving the PS solenoid with the proper PWM signal required to lighten the load at lower speed. If it were me, I would be putting either a multimeter or oscilloscope onto the solenoid terminals and taking it for a drive, looking for the voltage to change. The PWM signal is 0v, 12V, 0V, 12v with ...obviously...modulated pulse width. You should see that as an average voltage somewhere between 0V and 12V, and it should vary with speed. An handheld oscilloscope would be the better tool for this, because they are definitely good enough but there's no telling if any cheap shit multimeter that people have lying around are good enough. You can also directly interfere with the solenoid. If you wire up a little voltage divider with variable resistor on it, and hook the PS solenoid direct to 12V through that, you can manually adjust the voltage to the solenoid and you should be able to make it go ligheter and heavier. If you cannot, then the problem is either the solenoid itself dead, or your description of the steering being "tight" (which I have just been assuming you mean "heavy") could be that you have a mechanical problem in the steering and there is heaps of resistance to movement.
