I'm wondering if anyone who's done an engine out on a 955 Turbo provide some insight into where the access port for the torque converter bolts is?

From my research I have found that it seems to be positioned behind an engine mount bracket on the left hand side of the engine (looking at the engine from behind).

What I'd like to know is, what needs to be removed in order to take the bolts out. Does the turbo need to come off, and the engine mount bracket? Headers?

Any insight into this would be appreciated before I get cracking on this project.

 

I hope this picture helps. Getting this bolts out sucks, engine was on the floor with gearbox, axle completley attached.

 

Thanks for the reply, this is helpful.

Do you think it's doable with the engine and trans in the car? I mean I know it's possible, but how difficult do you think it would be?

One plus for me is that my car is RHD so wouldn't have to pull the steering shaft off as I can see you had to.

 

You cannot See the bolts and they are really good toqured. Best way is remove engine and gearbox. Remove the cat from the turbo und try working with a mirror and a lot of luck.
Im not sure maybe you can get the bolts by removing the starter too, but I never tried this.
I personally think refitting the bolts is a nightmare, if you drop one bolt into the hole you have to pull the engine again.
I manual swapped mine so never had to do this.

 

Yours is also a Turbo? Manual swap on that would be awesome, although surprised it can take the power. Was the box from an S or GTS?

I am going to have someone help me do the job and it sounds like he is keen to try doing it without dropping the engine. I've seen a few videos where people have done it so know that it can be done, but obviously it will be a battle.
Dropping the bolts or tool in the hole would certainly be a nightmare, I might try and think of some ways to mitigate that risk if we do it. Pulling the starter would be even more of a pain I reckon, I've had the manifold and coolant pipes off before and that took ages. Also, I imagine dropping the bolts from the starter cavity would be just as easy. Perhaps a little more room to work but unlikley to be worth the pain to get there.
I wonder if they make magnetic 10mm triple square bits.........

 

Can't get to the bolts from the starter.
The bolts are an extra fine thread and super easy to cross thread when installing. The access is at an angle which makes it easy to get them cross threaded. The good news is that if you drop a bolt in the access hole it can't go anywhere, the clearances are really small.

 

My car is a 06 Turbo S with Cayenne S manual gearbox, it is the same as Cayenne GTS . I think I am the only one with a manual gearbox swap.
Gearbox is completly fine.
