Hey,
I have a problem with a hydraulic pump (ABC), there is a leak.
At first it was out of the hydraulic oil tank cover (not tank steering wheel from the steering oil shows okay). From small cap rises from the oil and hydraulic oil, the oil is not return. The oil is always leaked from a little cover. And now after all this time I see that pump oil pouring herself. What is the problem of the car? ABC Pump, oil returns, or even something else? Thanks, Ilan

Hey ILAN,

It sounds like the pump has let go, follow the leak and replace what you find. I would wipe it off first and then run it for a bit to make sure of the leaks location.

Please let us know what you find so it will help others.

Best, Ken
