So I've been looking at the OAS for a while and thinking that it can be removed without removing the Turbo!! At first I thought about just bending the heat shield out of the way. But after further investigation I'm thinking that if I remove the downpipe bolts that "look" like they sandwich the heat shield in place it would not require turbo removal???

Please let me know anything that I have missed or just simply brain farted on as I'm drinking and thinking at the moment!!!

Thanks

Hi Mike.

I managed to get the AOS out without taking out the Turbo once. It was a real pain since it is so very tight and that I had to sit on top of the engine. My knees really wanted to kill me afterwards. When I reinstalled I used a shorter bolt down by the heat shield since you will not be able to fit the stock length (when removing it the threads forces it out wich is not the case when refitting)

Good luck!

Mike and Peder, I am actually at the same point after I do an oil pan/rod bearing/motor mount replacement. Alternator is also out, th eject steps would be turbo removal and AOS. Is the turbo difficult to remove other than the mounting bolts? The internal hex bolts look like they need to be removed carefully.

it is amazing just how many parts must be removed to do simple repairs on this beast to have clearance.

Do you have a spare AOS? If so, I have replaced the AOS without taking off the turbo by breaking off the existing AOS. This gets you access to the AOS bolts to remove and replace the AOS. I used to always have a spare AOS in my parts bin, just for this reason.

I once replaced the aos without turbo removal but it's extremely tight getting the bolts in and out and took some creative tool combinations to fit into each area. For what it's worth I'd just remove the turbo and replace the flange oil orings on the top and bottom. The turbo is easy to remove once the alternator is out of the way

Yes it is tight and crowded in there😊

Not difficult to remove the Turbo and if you do you can easily get to the AOS.

As I wrote I managed to change AOS and it seals without removing the Turbo but I would probably not do it again.

Damn it!! I just replaced the alternator about 1 year ago. HAHAHA!

So when working on a 951 this is the typical order of operation?

1) Remove car from engine ?
2) Do anything else that needs to be done.
3) Drink heavily!!!!

Thanks

Once the turbo is exposed, be sure to soak all of the bolts in your penetrating oil of choice, and be prepared for the possibility of a broken stud or two . . . .

If you are prepared for this, there might be a lesser chance of it happening.

Good luck!

The turbos mounting bolts can be removed with extensions and swivels from underneath but if you remove the alternator you can get at them with a rachet and a 6mm Allen socket very easily from the top of the car without m-fing the car and the engineer who designed it lol.

I'm still trying to short cut removing the Turbo. Is it possible to remove the 2 stupidly located bolts that attach the turbo outlet pipe to the block and slide out the heat shield?? Actually they look like they are somewhat more accessible than some of the other stuff.

Thanks

Ok one more question. Is it possible to remove the 4 nuts that hold the downpipe onto the turbine exit while everything is still in the car? It looks like one of them is not removable and maybe that's why the instructions on Pelican shows the turbo removed with the downpipe still attached???


Thanks

Since no one is answering I will. NO! NO! NO!

Hahaha

with the 944 turbo a 'short cut" will usually take twice the effort and time compared to the factory manual way!!

Mike Goebel

Please send me a copy of the factory manual!!
