Thanks chaps iwas expecting too get about that amount for her anyway.
I do have my own garage Badfish and would be willing to have a go at it i have done some of my own work . So would it be very hard too do or require specialist tools ?
I just assumed that it would need a new engine as the AA man said.
Would not say very hard to do "esp compared to a V6"
you should be able to find a link to a download of the GTV workshop manual and this will have the whole proccess in it.
There are a few specialist tools for the Job the most notible ones being:
Fly wheel locking tool
think you may also want a balancer lock but the belts on a TS may have markings to negate this.
All the tools can be got from totaly alfa relativly cheeply:
Twinspark (16V) Aftermarket Tools :: TotallyAlfa
They are also the tools that you would need for a belt change so maybe a bit of an investment.
Apart from those a socket set a torque wrench with angle indicator should do it.
Without taking the head off you should be able to figure if the belt has sliped by using a TDC indicator in conjunction with the cam locks. sus out TDC using the indicator and see if the locks fit, you could also sus how far out the cams are but rotating the crank till the cam locks fit and see what the TDC indicator says.
If it is definatly the head "AA can be wrong" then unbolt the axuiluries and remove it check the liners and pistons for damage/ condition "post a pic". as long as the damage is limited "bent valves and slight ding in piston" a second hand head, belt kit, new head gasket, and head bolts should get you going again.
You should go and have a good look in the day-light "have a good cup of tea and a bacon sandwich first mind" maybe take some pic's as they may help the forum help you
Again AA can be wrong did you lose alot of power when the noise started or was it just sound ?
