[QUOTE="marcusthehat, post: 3791124, member: 61430"] The nominal 15mm OD pipe from the pump to the valve block, is cracked somewhere near a bend, "pissing" oil upwards, but only when at maximium pressure (i.e. when the PRV is working) I had thought I had "near-enough" found the leak location, but v hard to properly see while "in-situ", and I figured that the crack would become visible after buffing up prior to brazing. NOPE, no crack to be seen, so I got the whole proximate area brazed, but on re-fitting it is still leaking. How do I best pinpoint the leak location? cheers mth P.S. I refrained from using the point of my finger to pin-point the leak. [/QUOTE]
