Hi guys sorry I keep posting but am really worried having had a zlet engine die on me before now
My dump valve has stopped working on me, it half opens on idle and will dump but under boost moving it wont???
Have taken apart and greased, checked all pipes are fine, even borrowed one off a friends scooby and got the same results (Baileys)
I wouldn't be that worried if there wasn't a blanking plate on the oe dv (done by prev owner)
Anyone had this problem??
