secondary air . pulled hoses off pump and seamed dry . but when i pulled hoses off on rear between valve covers it has moister and white sludge [ oil and water).does this mean combi valve is bad? also all vacuum lines seam brittle . pulled on the one one that goes down by plastic pipe and it came off easily. trouble is i cant see were it came from without removing parts.. also a reasonable place to find cross over pipe between valve covers and vacuum line replacement (vacuum line seams to have extra protection from heat) will try and check pump soon may need one of those too but first i need to replace vacuum lines and cross over pipe broke when removing to check.
