Maybe a stupid question but do you have to drop the oil before removing the hydraulic valve?
Cheers, Dave
As long as the car has been sitting still for a while, it should be fine as the oil just sinks to the sump. The valve is higher than the sump.

Be careful when you remove it as you can snap it (the case part) by wiggling it too much as you pull. It depends on how long it's been in there, the condition of the engine etc. There was a video about this but I can't find it, unfortunately. Might be wise to use some penetrative oil around the case first. In this video, it actually snapped and the guy had to drill it out! I don't think anyone wants to go there.
