Had a mare on Sunday. S3 8l. Valve cover gasket replace. All going well, new gasket on, cover back on tightening nuts 10nm with torque wrench and a couple stud snap. I then remove all the nuts again to remove the cover, but one nut seems to now be missthreaded and stuck on and it’s lifting the threaded stud. Its still in situ preventing cover removal. I then walked away.
I’m off next week and am in 2 minds whether to attempt to redeem the situation myself as I’m determined it won’t beat me, or call a mobile mechanic in. The advice I’m looking for is, are my thoughts now on the right track ...
1. ordered a new set of threaded pins for the head in case more give ( 2 different sizes - central studs (3) and outer (6) off of Audi.7zap.con) no’s 3 & 4 in the exploded diagram ... is this correct
2. Plus gas the sheared studs in lead up to having a go at removing
3. Remove the last nut still holding the cover down by using the 2 nut method so I can then see how much of the broken studs I’ve to play with
4. Hopefully enough purchase on the broken studs to remove and replace with new threaded pins .... do you replace immediately?
5. do you just fit these threaded studs by same 2 stud method until seated ?
6. Purchased one of those Chuck style stud removers ... are these any good?
7. Do I now need to order another gasket ?
Lost confidence in the torque wrench now,and I’m a little apprehensive of doing more damage by having a go. Also an exposed head and dropping something in gives me the fear. if I get to the stage of tightening up the cover again it’ll be done hand tight by feel . Simple job that just got harder
Really appreciate any experienced guidance
