hi, i recently found your video series. Having worked on these for ages its always interesting to see someone else working on them for the first time. Before you do anything else take the turbo off and remove that turbo gasket, it should only be the ring (if you have the groove) or the gasket. If you put both in there it will start to leak and it will be hell to change it as you pointed out. Theres also a specific torque sequence on the hot side to reduce the risk of cracking, which oculd be good to follow. If you want i can send over all the factory manuals if you dont have them, therese a bunch more in them compared to haynes which can be a bit shaky on this car. BTW, those turbo bolts look like std grade bolts, you should use something high spec that can handle the heat, or they will loose the clamping force over time. Ill gladly help if you have any more thoughts around the engine rebuild :)
@@hansgarage1751 its described in the technical bulletins, which i also could share if you want. That change came fairly early on, most or these cars have changed turbocharger sometime during their life, and gotten the turbine housing with the groove for the ring instead of the gasket. The ring weal settles less over time than the gasket and keeps clamping force better over time.
Great video. Not many out there showing step-by-step work on the 931. Will be valuable for years to come!
Glad it was helpful!

Thanks for the tip on the turbo gasket. It's curious that the PET shows both. I'll double check that to see it it's year model specific.

Excellent Cedric. If you want to reply with a torque sequence on the hot side that would be very helpful.

@garagecedric, I am also rebuilding my '82 931; I am at the disassembly stage now. Are the factory manuals you digital?
