My Porsche 924 Turbo: Fixing the

[@chrismadge7292]

And I thought the Super Charged 924 was a nightmare to work on, the Turbo looks even worse :0! I used stainless steel studs and Aerotight nuts all around my exhaust manifold, down pipe etc. Hopefully they will never seize! Aerotight nuts are stainless self locking - ideal for exhausts etc if you ever expect to take them apart again.

[@GarageBiljon]

Thanks Chris, I've never heard of Aerotight nuts but will check them out!

Should have cut the J Pipe and put in a flex sleeve on it. The common fail point of the J Pipe is the weld at the flange to the waste gate due to vibration. Putting in a flex sleeve dampens the vibration and keeps the pipe from breaking off.

True, but the previous one lasted nearly 40 years, so I will hedge my bets 😃

Brutal job on your back under the car with less than a meter of room to work. We're taking apart an '82 924 Turbo for engine rebuild and took the exhaust apart yesterday. Only broke one stud on the exhaust port of the turbo. Agreed that the 931 is tough to work on but that challenge is surpassed by 944 Turbo or 951. We did a trans axle rebuild and clutch replacement last year on a '87. That car is really fun to drive now and I can't wait to compare the 931 driving experience with a fresh engine.

[@GarageBiljon]

Haha, yes, we rebuilt the turbo on a friends 951 a couple of years ago and I remember the impossible access to nuts and bolts there as well! My experience with the 931 vs 951 is that the 931 is a rawer and more characterful and old school car. The 951 is quite a bit more refined and sophisticated, but I love them both.

Recently did the motor mounts on my 944, what a pain in the butt. You made it look so easy. Anyways, what is the link to that to you were using the short socket wrench? Can you please send me the link? Thank you and keep up the good work with your videos. They are awesome.

[@GarageBiljon]

Thank you Phillip! Have a look here: tinyurl.com/a7kmkzdw

@Johann, next time you have bolts & nuts not coming loose, come an borrow my 230v singlephase hand held induction heater, works like magic!

[@GarageBiljon]

Thank you Willem!

[@jeffhammond8969]

Jon, love your patience with this job. I think I might have thrown in the towel once the studs broke! Did you think about having the wastegate bread blasted and coated while it was out? I’m sure timing has at least a bit of input on that decision.

[@GarageBiljon]

Thanks Jeff! Every night as I came back into the house I told my wife that I am going to give up and have it done, but somehow the next day when I tried again with a different technique or tool I would book some progress and then I just kept going. These cars were insanely expensive to maintain back in the day, and I can see why; It was not built with serviceability in mind. Luckily my time is free 😅

[@GarageBiljon]

With regards to the bead blasting; I did think about it but figured this will be back to being crusty in no time, so decided to leave the rust as it does offer a level of protection in its own right.

[@BigFish246]

Great video, thanks for making this. Where did you source the motor mounts from? I read that left & right are different, and one of them are available? Can you share where you bought the motor mounts from and what part number?

[@GarageBiljon]

I bought the motor mounts from a Porsche specialist here in the Netherlands that had a bunch of rebuilt units available, even though I believe them to be NOS. But unfortunately they have run out of stock and they can't tell me if or when they will have more set's available.

[@clementclem7566]

Hello, I'm doing a rebuilt of my wastegate from a porsche 924 turbo but I don't find the rebuilding kit with the thermic washer. I was wondering if you can tell me where did you find this kit. Cordially Clément.

[@GarageBiljon]

Hi Clément, I bought it about 4 years ago from a guy I found on Rennlist, here is his website: www.performanceenginerding.com/products.html.

[@douglasshand]

Hi, enjoying the videos. I am slowly bringing a neglected 968 back to life. Interested in your thoughts on the Quick Jacks. I am deciding whether to purchase a scissor lift but not sure if it will be any better than the Quick Jack.

[@GarageBiljon]

Thank you Douglas! I am a BIG fan of my Quickjack, it is super versatile and very stable. A scissor lift might give you more height though and that is my only complaint with the Quickjack, it would have been great if it had just a little more lift height, but overall I have no complaints.

[@clintg6016v]

I’m doing this same job now, except that I’m replacing the turbo and Cerakoting the manifold as well. It is work!

[@GarageBiljon]

I have a tiny crack in the Manifold, so it will have to come out at some point in the future too, then I will go the Cerakote route too.

[@Bob_Sacamano1975]

Awesome video! Hope there will be more on the 931 on your channel.

[@GarageBiljon]

Thank you Bob, there will be some videos coming in the near future. She needs a new clutch and some other odds and ends.

[@maxboost259]

This has been my favorite video yet.

[@GarageBiljon]

Wow, thanks Max! It was a very tough but rewarding job too.

[@garagecedric]

Be sure to use studs and nuts made for the heat, then its easy to remove them next time :)

[@GarageBiljon]

Agreed Cedric, that I why I went with the expensive original Porsche studs and nuts. The previous guy didn't and made this job so much tougher than it needed to be 😅

[@garagecedric]

@@GarageBiljon Can also be from other cars, vw parts are cheaper for example. Buying from porsche themselves should be good stuff. Regular studs really "weld" stuck and oxidise at stunning rate :)

[@GarageBiljon]

True @@garagecedric and I often shop in the VW/AUDI parts store, but on this job I did not have time to cross reference parts. But to be fair, fhe parts were very reasonably priced from Porsche.
