Bleeder Screw on an 88 325is steering rack?

[emcdonald]

Hi Everyone,

I just picked up my 5th E30, a 1988 325is that the previous owner had swapped some plastic bumpers onto. I'm planning on doing the UUC BBK and some other stuff, but the power steering was leaking. I originally thought it was the hoses at the rack, because the PO had replaced the rack with a used one and didn't use new crush washer, but it turned out to be one of the hollow bolts was cracked. Got a new one and thought that fixed the problem, but it was still leaking....

It turns out there is a hole on the right hand side of the rack all the way at the edge on the top of the tube facing towards the back of the car. I can't see in there to see if it's threaded, but there is a steady stream of fluid coming out when the wheels are turned all the way to the left (or most of the way...) I also got fluid to come out of the hole when I squeezed the boot on that side.

I don't have ETK anymore, but was wondering if someone knows if there is a bolt that goes in there and the size of it? Any help??

Thanks,

Erik

I think that hole is pressure relief for the bellows. If fluid came out of the hole when you squeezed the bellows, the rack seals are shot. Replace the rack.
