well time for a wee update on the issues
firstly, my headlight bulb blew at the perfect time, an hour before i was away to fit hid's, fitted them, they are stupendously good
the repaired boost pipe is still holding perfectly
the fuel lift pump i thought was totally dead has started buzzing, so i dug deeper and found there were no sheaths on the electrical terminals so they were badly corroded, cleaned them up a bit to see what happened, the pump now buzzes alot louder under the car and the wee hesitations i was getting on elevation changes has more or less gone, whats left seems to be the result of a perished induction hose which is due to be replaced anyway
found an uncapped vacum pipe so blocked that off, my turbo feels more eager to boost
however, there is one big issue, the clutch. it is 100% fine when the car is cold, but once it's warmed up and has been running for about half an hour, i start getting odd noises and the clutch under strain will vibrate and jam the pedal to the floor, seems to all be linked to a faint clonk i get now and then....result? the DMF is out of tollerance and needs changed, the sticking is a jamming cylinder either master or slave
ouch
that said, its only just going in no more, so not critical by any means, the pedal can be raised by toe and pumped to reset cylinder and all is fine for a while again, and i know how to stop it jamming when it starts vibrating, so it can be managed for now until needs must
