Next thing on the list was the rattling exup valve. Unbelievably the exup cover had 3 different bolts fitted and then when i removed the cover the bolts holding the exup to the exhaust were battery terminal bolts! They are as soft as sh*te!! The first snapped the head clean off, but i managed to get the other two out.
I removed the snapped one with big vice grips on the remaining thread and slowly removed it
I stripped the exup down thoroughly cleaned it and gave a light rub down until shiny. I then thoroughly coated in high quality heat resistant lithium or ceramic (grey stuff) grease, reassembled, adjusted cables and hey presto a perfectly functioning exup. Oh.. while i remember the spring that sits between the pulley and valve were missing, so i made one and it seems to work well. Fitted flip screen courtesy of clanadam. It was clear from top to bottom, so it showed behind the clocks , i masked it off and sprayed the bottom of the screen with some satin black paint. Looks good, hopefully it will work well. Find out tomorrow when going to work.
