Well I did this fabulous job of rebuilding the engine. Running fine. But an hour or two into driving the car for the first time in a year I get a power steering leak which is keeping me off the road.
I took the pump out and separated the two halves of the housing and found the large oring cut, or torn. It almost looked to thin to be the right o-ring. I also found there were only three of four housing bolts in place on the pump housing. The fourth hole was painted. It looked like the bolt was missing from the start.
There is a bolt head clearance problem in the upper right bolt area on the pump and another bolt that holds the steering pump bracket to the block. The only way I got them both in was eliminating a lock washer on the forth pump bolt.
I put in new o-rings, put it all back together and no leak. But air I got. I tried a number of steps to purge the system. But there must be an exact sequence to use.
Just when it seems like it is purged of air it comes back. I took it on the road for half hour and then noticed when I turned left there was no power steering, but if I turned right there was. Wierd.
When I got back home I purged it again. This time I opened up the bleeder screw on the steering shaft housing and let the bubbles come out on there own until only fluid started to come out.
I started up the car, attempted turn the wheel which shut locked up the unit and shut the engine right down instantly.
There must be a specific sequence to purge. I tried to purge with a tube back into the resevoir by turning the wheel back and forth slowly until no more air came out.
Getting air into the system is not good on the O-rings because if high pressure air pushes past one spot on the o-ring it is like cutting it with a knife.
Anyone know?
Thanks
