yes welcome to bx's
that valve. everything imaginable is packed into a small space. Like putting 10 lbs of taters in a 5 lb toe sack.
no fun to work on!
Mark everything well. Use your phone to take plenty of pictures so u know how it goes back together.
the most common leak points on the bx2200 was the power steering hoses I bet I did 250 of them! They rub and then they leak. I put sleeves on them but because of the design it only prolonged recurring leaks.
