What a great video!

Thank you very much for posting "The Great PutDown". It is quite special.

Seeing the subtle differences in how Mulholland used to look in the 60's brings back plenty of good memories for many of us that were there at that time.

And it was an awesome time to be alive in America.

The fuel injection lines were dirty and discolored after so many years of oxidation.

They looked like they just needed a good cleaning so I used steel wool to polish them up, and it worked.



With some hard work, 32 years of scuz, dirt, and staining came right off.



I was amazed at how well they shined up. Look at the lines in the sunlight



These lines were dark and filthy when I started, now they are clean and bright!

[Banning]

After timing the MFI pump, and all lines hooked up, we are ready to install the motor back into the car.

After a fuel system check, the motor can be started.
Like a Firebird (not the car) rising from the ashes, it will be re-born, again.

I can't wait........

Thanks Derek, without this thread, who knows how many years might have passed until the Carrera lived again?

Remember, first ride...

Thanks again.

A few guys from Perf Prod showed up at my house at dusk, they were on bicycles.
I know Ron who works there, and he brought his friends.

I gave them a tour of the Porsche and the factory performance manuals.
It was fun to talk to them about Porsches.

I told them about this thread on Pelican Parts, they had heard about it. They might join us next time we meet on Mul.

They left just after dark set in.

It reminded me of the old days when someone would show up at my house to check out their race car right about sundown,
preparing for a fun night on Mulholland Drive.

We need to start getting organized for next Friday the 15th. Who's in ?

[slodave]

I need to get my pedal cluster done .

Sounds good! I would have been done "two weeks" ago if it wern't for all the distractions . Tires and registration challenges are all that's left. Let's roll!

Derek, get your digital camera ready...

Now that the MFI lines are clean, they need to be fished thru the throttle linkages and fuel injection stacks so that they can be fastened to the injectors.



In order to get this done, they will have to be separated and put thru individually.



After taking apart their connector, each line can be run around to it's own injection spritzer.



When all injection lines are in their place, it looks like this.

[Banning]

With the MFI pump in place, you can see the close placement of the lines to their connectors located on top of the pump.

I see the problem! It's those durn red caps.

After adjusting the lines by loosening the fastener that connects them, they fit perfectly on their respective MFI outlets.
The opposite end of each injection line was fastened to it's own injector nozzle as well.
Injection lines in.

[Banning]

On Porsches, it's always a good idea to use new washers and nuts whenever possible. These are for fastening the MFI pump to it's stand.



One nut for the MFI pump is located close to the injection stacks and is difficult to get to.



Here is a close up. Thank goodness for swivel-sockets.



These lines located on the other side of the pump are for lubricating the pump. The small one is pressure to feed the pump, the other is for oil return.
The MFI pump is like a miniature engine with cams, a crankshaft, and many moving parts. It is quite complex and requires it's own oil supply.

[slodave]

It does not look like the nyloc is actually grabbing. Where there nyloc nuts holding the MFI pump on originally? I don't remember.

[Banning]

Now we come to a very important part of what we're doing. That is, to get this Carrera back on the road again.

So since we are about done, it's about time to time the MFI pump to the motor.

The old belt had very low miles on it, but many years had passed. Always replace the MFI timing belt if the motor is old from mileage or from age.





This diagram showing the firing order of a Porsche 911 is here for those of us that need reminding, probably no one here.
Keep track of what cylinders are where. It makes life a lot easier when working on the motor.




Now the first thing that we do is move the crankshaft to TDC (top dead center) on the compression stroke of the number 1 cylinder.
To do this, move the front pulley so that the mark on the blower housing (crankcase seam) lines up with the Z1 mark on the pulley.
Make sure that the distributer rotor is pointing to the notch on the distributer housing (number one in firing position).

Next, turn the motor 360 degrees more until the Z1 mark lines up again with the crankcase seam.
Now we are at TDC on the exhaust stroke (cylinder #1), and about to start the intake stroke. This is also called overlap because the intake and exhaust valves are overlapping; as one is closing (exhaust) and the other is opening (intake).

Now turn the motor over just a little more until the FE mark on the pulley lines up with the crankcase seam.
The engine is now 40 degrees after overlap TDC/#1 and fuel will spray into the combustion chamber just as the intake valve is fully open. Awesome!



The other part of this timing procedure is the position of the drive pulley on the MFI pump.

There is a notch on the back of the MFI pump located on the coller that's on the housing.
It should line up with the notch on the aluminum drive hub that drives the MFI pump.

See detail in photo:




With everything in the right place, the belt slips on, and the MFI is now timed to the engine properly.

The belt still needs to be adjusted so that it is tight.
By tightening the nuts that hold the pump down and moving it away from the cam that drives it, the belt is tightened.

NOW LET'S PUT THAT MOTOR BACK INTO THE CAR! I WANNA DRIVE MULHOLLAND!

[Banning]

Last night at about 10:30 I heard helicopters outside and they were LOUD.
Out the window I saw that a car had gone over the first Identical and there were emergency vehicles all over Mulholland.

This morning I was able to photo the car being taken out.

It was a long way down the mountain, maybe 400 linear feet.
The car must have been going real fast around the corner and have been fully loaded because it blew down the new gaurdrail to the ground.




From the imprint marks, it must have rolled side over side all the way down.



Police were all over and investigators too. Probably a fatality.



Mulholland was blocked for awhile during the operation.

In over 50 years of living here, I have seen many accidents where cars or motorcycles went over the edge or had head-on collisions in The Identicals.
This is a very dangerous spot, along with Carls, Deadmans, both ends of European Straight, Sideways, the top and bottom of the Esses, and a few more.

Always drive more carefully when your car is fully loaded, it handles differently.
And don't forget where the potholes are. A pothole almost killed a Porsche driver last year when it caused it to flip over in Sideways. Old Man Gary saw the aftermath.
Please be careful.
