Well I decided to fit my RS injectors which have been sitting around for a while - this went well thanks to Fishfaces excellent 'How to' guide to which I will later add my comments as I did it slightly differently. Only real problem was removing and refitting the standard air box (yes I know I should bin it!) which is a right pain, as we all know. Car started fine and showed no faults so off I went to 'test them out' as it were. Drives great, smooth and responsive....however...on arriving back after 20 miles a cloud of smoke seemed to surround the car - at first I thought I'd lunched the clutch, but it turns out its steam and a couple of pints of coolant have exited the system. It would appear that the problem may be a leak under the airbox, possibly caused by all that ragging on the airbox which is required to get it out from the engine bay. So, looks like tomorrow I'll have the joyous job or removing the airbox again...I just wondered if anyone can confirm that there is a hose under the airbox that is the likely culprit? Steam seemed to be coming from between the MF housing, plenum area. Cheers guys...
