R34 power steering

[drifter17a]

Hi all

 

my r34 has been off for over a year with occasional start. Today I noticed a lot of noise from engine bay when turning the wheel as if power steering has no fluid . Checked and loads of fluid had flowed out of the resorvoir. Has anything been blocked/ destroyed? Maybe fluid can’t get into pump

and flowing out ?

could it need bleeding by turning steering side to side?

thoughts?

No idea. It's too weird.

Does the steering feel heavy when you turn the wheels? Any puddles of fluid on the floor or that you can see leaking from anywhere?

You could try bleeding the system, if it’s making a whining sound when turning the wheels then that’s a sure indication there’s air in there somewhere. Start the car and remove the reservoir cap, then turn the wheels from left to right a few cycles and then check if you see any air bubbles rising to the top of the reservoir. Top up if necessary and repeat.

Otherwise, I can only suggest that your pump vanes have seized or that there is a perished seal somewhere??

Yep it is overflowing. All was working fine but been off for a year so guess something may have seized. Steering is heavy yes

 

i will raise the front of the car and will turn side to side to test id bubble goes away

Or, just take PS pump off and inspect?

Does no-one do this any more?

Too much work, but guess I will have to

Easy place to start is jack up the front end, turn steering wheel lock to lock and see if any air bubbles purge. If nothing happens it's probably time to pull the pump and inspect. It could also be a line is clogged for whatever reason and you need to isolate the part of the system that is blocked on the high pressure side causing the pump to be unhappy.

Mate. Your car is like 20 years old. Expect that the rubber bits (seals, hoses, etc.) needs to be replaced.

Best bet is to carefully go through your engine bay and try to find parts that need replacing (e.g. rubber hoses).

for your power steering issue, best bet is to pull off the pump (not that hard, you can buy basic tools from Supercheap et. al. to remove it) and then inspect/get it rebuilt.

*edit* forgot to add, no idea on R34, but my R32 HICAS computer has been playing up since I bought it (10+ years ago), so I just disconnected the small plug to "disable" HICAS but keep my power steering. So something extra for you to look into.

It may not be relevant to your situation, but when I had the issue of air getting into the system on my GTT, I found there was a tiny hole in the aluminium cooling pipe. Enough for air to be drawn in, just not enough to cause a significant leak.

Looked like the previous owner had chosen a bad place to attach the earth clamp of his welder and tried to mask this with a piece of mesh sleeving 🙄
