heres an update guys.

so the headgasket was complety hammered, obvoiusly he replaced it. Valve was burt out as i said and the starter motor was gone and the battery was completly finished, replaced all, car started, fired up perfectly, idled at 800, no missfire, plenty of power as compared to as before, everything works....

but me and my luck..

when i came back round from testing the car, i pulled up and turned it off. now...

wont even click over. starter motor got replaced as it was still under warrantee from the 2 days it had been on the car... nothinng. the DAMN engine wont turnover. Battery is fine and tried a jump.

what can it be now. this is my last last last attempt, then the cars being broken. almost half a year...

just sitting here thinking about it, i think it could be a problem i had ages ago with the ignition barrel thing. the black box on the left side, when i took it off and used a screwdriver, it worked every time... apart from this, me and the mechanic are compeltly stumpd as to why it wont start up.
