p/s leak from pump cap?
Hi all,
I have been trying to diagnose a power steering leak on my 80, it always seems to maybe pressurise and leak from the from the pump cap. I Fill the reservoir to the correct level, bleed the air by having the front wheels off the ground turning about 10 times lock to lock. I have access to a vehicle hoist so I can inspect for leaks , letting it running for 20 mins no signs of power steering fluid anywhere, go for a 10 min drive, let it sit for 1/2 hr still no leaks. Next morning a 10 inch puddle of fluid on the ground. Done this twice now. always wet from pump cap running down the side. Just seeing if I'm forgetting something simple before I start pulling things apart.

As you have explained your problem, I just can't think of a reason why the pump cap should leak fluid while resting overnight.

Thanks for response Jim , I'm unsure how old the pump is the hoses were replaced a few years ago along with the control valv and ram there is no evidence they leak , just wet on the pump dripping onto the control and on the floor, I own a 81 aswell for the last 16 years and never seen leak (puddle) like this before , I wiĺl try the cap from my 81 to eliminate that first.

Possibly it is being overfilled. After it burps out the fluid, just drive it again and see if the PS works OK.
Later, check the level when HOT from driving.
