Hey Hilton: Clamps? You mean hose clamps on the ends? The blue hose should not have hose clamps put on it. They will cause it to leak.

The one that I remember most vividly was replacing the motor mounts on my first 928. I had just bought the nine-volume set of manuals on sale from a California Porsche dealer, and was dismayed to discover that the mounts aren't even mentioned in the manuals. There was no knowledgeable internet support in those days, so I had to muddle thru by myself. A nasty job - I had not really started cleaning the car yet...

So how did you mod the factory tool?

Rob,
That is the tool I used. It is fine with the engine out of the car. With the engine in the car though it is useless.
I also found the steel to be much too soft and it bent very easily.
I built a simple piece which allows the tool to actually bolt to the cyl head. This allowed a better angle of attack as well as an easier removal and installation.

Corroded rear pivot bolt removal! My first 928 spent its whole life in Chicago and was driven year round. I destroyed both rear pivot bolts trying to remove them. I soaked them, heated them, pounded on them, and eventually had to cut one of them out. The other one came out eventually, but I still replaced it.

Yeah, the blue hose is just soft silicone under a braided sheath, and the flow in that hose is just gravity (no pressure). Clamps will cut into the hose over time. I have found leaking ones with clamps that had a cut under the clamp - pulled off the end, cut off the split part and shoved it back on without the clamp - leak gone.

But I'd be a bit worried about all the left-over parts after reassembly...

I had an minor epiphany when doing this job a few months ago.. The rear threaded steel insert piece in the bracket, where the through-bolt connects, actually slides in the alternator casting. A gentle tap with the mini-mallet moves it back slightly, so it fits up around the block bracket prettty effortlessly. Of course, the bolt still seems to run into the fan console at the front, but just loosening the two top bolts above th radiator means you can move the fan console enough to get it lined up without disconnecting anything else on the radiator.

Nicole,
I can get the dash and heater core out in around 2 hours and everything is pretty easy to access. So I don't find that one too bad.
Sean,
I agree the alt isn't my fav job, but I think you should try the springs. You will have a new worst enemy.
I used a leakdown tester and put 100 psi into each cyl. This holds the valves up.
However while installing a couple I bumper the valve with the upper perch and the valve dropped down a little. Thankfully they don't go far and a magnet pulls it back into place with ease! It took me 6 hours to do cyl 1 and 2 and the exhaust side on 3. After I made a tool it took me 2 hours to do the rest.

It takes me 2 hours to mentally get ready to pull a heater core or evaporator....
