Power steering leaking

[shaz2010]

Lads has anyone come across this before, on starting the car the after about a minute the power steering fluid is pissing out from the cap ??

Reservoir Cap knackered? Air in system causing it to over pressurise?  Is it doing it without even moving the wheel? As in a minute after you have turned the car on it is leaking?

[shaz2010]

Hi mate yes even without moving the wheel! Just bought a new cap from Toyota and it still does it. Just removed the reservoir and cleaning it out as I read crude can cause this in the bottom of the reservoir. Just about to put it back on. Seemed there was a bit of shite in the bottom. But not sure it’s that.   If there is air in the system when I put the new cap back on is there a way to bleed it.

Also does it matter that the new cap has a different side indicator? Old on the right

The reservoir isn't very deep so I would have thought your new one would be touching the bottom and has maybe punctured the filter? And it looks like the new 'Cold' is lower than the original so the reading is different and would be wrong. I'd go back to your dealer and make sure you get a like for like replacement. You can jack the car up and turn the wheels with the engine off to help bleed it, and the same again with the engine on.

Ah ok, iirc both my JDM NA and TT are the same as on the right, the one on the left looks to be an early cap between 1993/05 to 1994/05, part no: 44305-24030. I don't think the type of cap will affect your issue though as it should screw on and seal the same and wouldn't foul the reservoir (obviously) as it's shorter, so you should be fine, ignore my previous comment. Although once the issue is sorted I'd try using your old one again as the level height does look different. Keep us posted, hopefully it all it needs is a bleed.

System is A) to full and B) full of air. Jack the front so the wheels are off the ground, go lock to lock a few times, get the air out

Don’t no if mine being a Uk spec would matter and that’s why it’s bigger ? Not sure. Yeah I probs will as it’s doing it with both.

Cheers mate I’ll jack it up tomorrow, would that be turning while the engine is started? And with the cap on.

Engine running, cap off so you can see whats going on. When did it start doing that?

This. If it hasn't been changed recently, I would suspect a seal has gone and is letting air in somewhere.

Cheers 

just on Sunday took it for a run as I do every other weekend. Stopped about a mile from home and got some more fluid and topped it up and got home with out doing many full turns. Was pretty much a straight road. Hopefully I’ve not killed the pump but there was still fluid in when I got home just was leaking

My NA reservoir was very blocked and was starving my pump for a little while before I sent it to Chris Wilson to be rebuilt. He said there was evidence of cavitation but it was rebuildable and it’s been fine for coming up to two years now, so I think it should be okay, maybe only a rebuild at the very most (if it’s not a seal in the pump that has gone)

Is that due to lack of use or old fluid?

Old fluid for sure. It was black and smelt burnt, probably hadn't been done in well over a decade, same with the coolant. From what I understand my NA was in daily use since import (2003) until about 2016, then it was driven on the odd weekend until I bought it, so I think it's more lack of a service rather than sitting. I did a flush using this method (@shaz2010 - this might be helpful if you want to flush your system once you find the issue), thinking i'd caught it in time but the whining got progressively worse. White spirit etc. wouldn't shift the crud in the bottom so I just fitted a good used one and coupled with the rebuilt pump it's sorted now. If your fluid is still red/sweet and has been changed somewhat regularly I don't think it'll be an issue you'd experience.
