Hi guys

I know issues with HICAS have been posted 65 million times before, but i have a problem that i cant find the

answer to after searching many threads.

My car has had the HICAS removed by the previous owner. The problem is I have a power steering leak that is difficult to find, the rear of

the pump has been closed with a banjo bolt with no hose coming from this. I think this may be the problem, but my mechanic put a new stonger

washer on the bolt which slowed the leak down. The leak seems to be from this area, its hard to tell as when the car is hot it makes a mess all this side of the car.

What im asking basically, will having the rear of the pump closed off be causing it to leak under pressure under hot oil temps?

How could this be fixed?

Sorry if this seems a little brief, but its difficult to explain.

Cheers!

Hot oil will become thinner and will be more likely to leak out if the leak is small enough. This is what id be doing. Clean down the entire area with degreaser and make sure you can see the area well, IE: get a light if you need to. Start up the engine and get someone to load up the steering IE: full lock and watch for leaks. That will help you identify where the leak is and then you can either replug the banjo fitting properly or get the pump rebuilt as it may just be a leaking pump seal.

Good luck :D

we have plugged the rear of the pump with a bolt and copper washer - no leaks. may not even be coming from there....spray the whole area with degreaser then check what is wet after a quick drive

Hey Duncan,

Did you work on the car for the previous owner?

sorry buggor34 i meant the royal "we", I have blocked the rear stage of mine without any leaks

michael - yes you will kill the pump if you just block up the rear stage, I killed my first one this way. You need to pull the back off the pump and remove the blades on the impellor

can you run a line there and use that to hook upto a cooler and run the line back from the cooler to the front stage?/line by using a T piece? As i dont have any of the pumps?/solanoids for the HICAS on the left of the engine bay there anymore.

indeed you can, or return it straight to the resoviour to cool it before it heads out thru the first stage.

if I did it again I would do it this way, but instead mine is one stage only - resoviour - pump - cooler - steering rack - resoviour. Still boils over during track work even with good fluid. cooler is pretty small though only about 10cm high

its worse than that mate, I'm talking about a proper aftermarket core not the super crappy standard finned pipe thingy. Fluid boils every session for me (say 8-10 laps or 15 min), but until this year we were not allowed to run a bigger cooler.

Funny you should say that Duncan, because thats what has been done to my pump (bolt with copper washer). The mechanic found the leak

& it was from the front seal on the pump :worship:

Do you think it would be better to take the impellors off the back of the pump or route a pipe somewhere? If so where would be the best place to run

the new piping?

Thanks heaps!

Buggor - this is all Skyline 101 :D Many a detailed thread.

People remove the rear stator, but most people just re-route the lines. Check the pictures people have posted, compare that with what you see when you get under the car and its dead easy. Cut some steal pipe, fit 30cm worth of hose, few hose clamps - wo la!

The trouble is that the previous owner has removed all the lines that were associated with the rear of the pump. & just blocked the hole with a bolt & copper washer. Which i believe has caused the pump to blow the front seal.

I have searched through many threads and am confused as to what option is better. Do you have any links to any good

threads?

In your opinion would you while repairing the pump take out the impellor or add some fittings and hoses to the rear of the pump and use an aftermarket cooler etc? I do plan to take it to a few track days in the future.

Cheers!

well putting everything back is all too hard, so stick with what you have. if the rear stage is blocked off and its done more than a couple of hundred ks, they must have taken the blades out of the rear stage....otherwise it would be dead by now

    • It only looks tidy, as most of the stuff that was on the whole back wall, is now in the trailer to go to the tip, or has been shoved in my 2.2x2.4m "Spare parts room", and now I can't get to anything in there Ha ha ha I could definitely do with a bit more space, but I'd just end up with your problems I'm going to enclose the car port beside the garage, and move a lot of stuff into it I think. OR... It will be setup as a fabrication area, and the main garage will have parts storage in it. I'm not sure yet... Need some pictures of that big shed you've got with the bikes and Skyline in
    • No. I think it's gone. 😭 I think you can get body coloured ones on eBay so I think I'll get one of those... Or just hang a red ribbon from the hole and whack a TOW sticker next to it.
    • Can't say I've had a bad experience with one on my car, then again it only gets washed once or twice a year... The wheels on the other hand, get a good spray often due to my shitty dusty pads.
    • @MBS206 thats pretty neat and tidy to me!  I'll get a photo of mine when I'm out there next. It might require multiple photos to understand the scale of the atrocities though... In total I have 4 sheds of varying sizes and layouts. Main shed is 14x8, second shed is 3x8, third shed is 11x2.5, fourth shed is around 6x4.  All are pretty much full.   The main goal of my cleaning tsunami is to make the main shed predominantly car and motorbikes only. Second shed is my metal fab room (2 x bench grinders, drill press, bench belt sander, metal band saw, scrap metal storage and some of my garden tools.  3rd shed is more bigger garden stuff, storage for engine crane, jack stands, concrete grinder, concrete mixer, air compressor lives there, and it now has two 2mx2m pallet racking shelves with itemised boxes holding building stuff, electrical stuff, plumbing stuff, etc, etc.  The 4th shed is Ryobi electric ride on mower, mini boom sprayer, ancient Kubota tractor, more garden stuff!  I have got a lot of shit....  Then there's the pool house (8mx4m) and the pool pump shed (4mx4m).  I built all of the sheds over the 11 years we've been here.  The main shed was a Ranbuild kit, the rest are all custom made to fit the areas available. Building the main shed taught me a LOT as I had no idea about building anything prior to that!  I've still got one more in me. It will be my man cave which I poured the extra concrete for way back when I poured the concrete for the main shed. The idea is the Skyline will be a centre piece of the main cave once (if...) it's finished.  I told my now 14 year old son yesterday that I will 100% drive him to his year 10 formal in 2 years. Still a long way off but at least I now have a date to work towards! 🤣
    • Modern oils are amazing. Add tyres to that as well.
