Power Steering Leaks.

**Spasso** · 04-26-2006, 01:56 PM

Hi Guys,
I just picked up a '94 530iT to go with my 530i and find that it too has a slow leak from somewhere in the power steering system, located in an area that appears to be above the PS pump. The leak area and splatter pattern under the car is identical.

The low pressure hose has been replaced on the iT and the system still has the leak, about a pint every 800 miles.. No noise comes from either pump and both work fine.

Before I dive in on this project (great, now I have two of these) is a there a common place on the system that eventually leaks on all of the V8 cars or is this just a coincidence?.

Thanks, DJ

On my 90 535i, 5 spd, 105K, my PS leaks were the clamps. BMW uses crimp clamps. Fix is to replace with worm gear ones. FYI, make sure you use the correct fluid.

I doubt the problem was with the clamps. Many people would argue the crimps clamps work better because they provide a more uniform sealing surface and don't make themselves oblong.

Usually on older cars the hoses are shot and it's a good idea to replace the clamps as well. Don't know how different the V8's are, but my PS hoses were due for replacement.

I was just under mine this past weekend installing a set of Powerflex poly thrust arm bushes in mine and came across a PS leak too. Not bad, but something I need to address. In my case, I could swear it looks like the compression washers at the pressure/outlet hose are leaking. I half thought about tightening them, but with Murphy's law strong in my life I figured I'd just better replace them. With my luck, I'd strip threads or somehow make it worse. I have to keep remembering that this isn't like working on my old Pontiacs!

I thought the same on my sedan. It appears the drip from the banjo fitting is there just because it is the lowest point in the system.

Does any one have recommendations for sourcing a new PS pump on the outside chance it is failing?
Thanks, DJ

Be careful with that bolts, they are hollow inside so that the fluid can run through it. I found on my car after I bought it a leak, and guess what: the p. owner had tightened it too much and the bolt was broken.

whats the process for changing the power steering hoses?

Tse! Tse! You are using a 3/4" drive torque wrench as a ratchet wrench.
