Cheers mate. I did give them a squirt of said stuff and the nuts and studs I could see looked in pretty good condition.
To add to insult, the turbo gasket is blowing too, but I have it booked in next friday. VW wouldn't entertain it, so I have to take the car to one place, they take to turbo off then they take the turbo to an engineering workshop then they take it back to the garage to refit.
I'm going to try and get the day off work so at least I may be able to smash out the cat while the car is in bits. knowing my luck I won't get the day off work and I'll have to do the job all over again myself. Or, maybe I should just leave the damn thing alone!
