Dad's car came to a new (temporary) home today...
 

Went down to visit dad's today, brought home a car.

Ok, so that may sound a bit simplified, and I did make plans to get the car - I was expecting to be a little closer to ready for engine installation by now.

Pictures? Sure - here's one:

First order of business was to take a look in the engine compartment for the impending engine install. I will have to buy a new firewall sound barrier. The old one is shot (no surprise there) - and there are a few more hoses that look a little rough that are asking for replacement.

Question (for anyone who may be listening) - what is the black box on the passenger side of the engine bay, which looks to have two vacuum related hoses on it? Looks CIS related, but I am still learning.... It kind of looks like a "charcoal container" like modern car/fuel systems have. I will try to post a picture - but I am sure there is a more experienced wrench that may know what this does....

"black box" in the engine bay
 

Well, a picture certainly is worth 1000 words in this instance.

There is a small vacuum hose attached to this box, that I was able to trace up to the fire wall, and then it is kind of "ganged" with the fuel lines for a little bit, then looks like it appears to go into the cabin.

What the heck is this black box?

and.... I broke one of the vaccum lines (the small one) when I literally touched it with my shopvac.

On the parts list to purchase from our host:

Metal-to-body engine seal
Both of the hoses that go to the "black box"
A sound barrier (on the fire wall)


...

I believe it is the charcoal canister for the evaporative emmissions system.

Progress... what the hell is this wire fore???
 

Today, I was able to put a little time into working on the car. I was waiting on the CIS airbox to be delivered- so I took a little time to sort a few wires, and install new rear shocks.

http://forums.pelicanparts.com/uploa...1364609610.jpg


Oh yeah, I pulled the rear bumper - because I figured that I will need all the room possible to install this engine/tranny combo in the near future.

When I pulled the bumper, I found a couple things:
There is a wire that looks like it's not been performing it's function for quite some time - long before the car started this hiatus...
General location: Driver side, near the bumper, but not the lights for the license plate. The corner markers and brake lights worked OK (according to dad) prior to "storage".

Any ideas where these are supposed to go? The cloth wrapping indicates to me that they are not post production adds.... Looks like they are copper-braided wires, and I cannot tell what color the insulation was originally.

Finally, looking over to the passenger side of the "engine room" - the rail that holds the "engine room seal" in place is broken. It looks like some collision work was done here, but it's not so bad. The undercoat is missing, so I may have to put another coat here. But - if you look close - the seal rail is broken. Or, more accurately - there is a large amount of the rail missing. ("Rail piece" ordered from our host earlier this week - pending shipment).




Can I get away with doing a pop-rivet to attach the rail (for the seal) to the frame? Or, should I get someone who can weld the rail? To that point, I don't see any weld witness marks in the existing rails. Can I use a real good glue to attach this rail?

Alright, I took another picture of the area on the passenger side of the "engine room" for better viewing ability. ...Can I get away with riveting the new "rail" in place here?

CIS airbox frustration (help, please!)
 

I received the used airbox from a fellow pelicaner for a reasonable price - but alas: nothing is just as easy as just throwing the fuel distribution device and throttle-body on the thing and calling it good.

When I inspected the airbox, (from a 78 euro) - it looked like things would be bolt 'n' go, but I was corrected when I found a problem that required splitting the top from the bottom of the airbox.

http://forums.pelicanparts.com/uploa...1364754191.jpg

On the left: the bottom portion of the 'new' airbox.
On the right: the bottom portion of the old airbox. I could not get the metal (what looks like) distribution unit out of the old airbox with out splitting the two.

Now, I am faced with a problem. As you can likely see, I have system that has to be put back in place, but I have to use the 'old' lower half of the airbox and attach it to the 'new' upper half. Seeing that this area is critical to the function of the system, I need to seal the upper and lower half of the airbox - air tight.

Any recommendations on what to use to seal the two pieces back up? I don't think this is a place to use superglue and call it good.

The insert was Porsche fix for blowing the airbox,, directing the coldstart gas directly to the air tubes. You still need a pop off valve and both items will work when put back together. I would use a slower drying epoxy that would allow you to get bothsides together and the screws in before set up. JB weld comes to mind.

One vote for JB weld. That stuff is pretty readily available, so I am leaning in that direction.

I read a post from a some years back where there was a fellow pelicaner putting his airbox back together and used a material called Devcon Plastic weld ii - and then reported a couple years later that all was well. I would like to give this stuff a shot, but have found that this epoxy is not (easily) available to mere mortals like myself.

So - I will clean the mating surfaces today and give JB weld a shot.

CIS Airbox: re-assembly
 

Alright, I have cleaned the sealing area of the airbox.

While I was at it, I went ahead and cleaned the rest of the thing prepping for re-assembly.

The plastic tongue and groove system is pretty nice, but I've got some missing due what looks like a previous attempt at sealing this thing.

http://forums.pelicanparts.com/uploa...1364838931.jpg

Thinking that there may have been some back-fire action in this airbox's previous life...

http://forums.pelicanparts.com/uploa...1364838990.jpg

So, what I've decided to do is give it a go with JB weld, and install the screws to get the new top part to seal to the old bottom part. Then, (and this is likely overkill) I may go back and hit it with some high temp silicone to seal it up.

Airbox assembly
 

Today I shot over to the local autoparts store to get some JB Weld to assemble the airbox this evening.

Seeing that I work very slowly, I decided not to go with the "plastic welder" type stuff, because I would have a problem with it hardening before I could successfully put the two halves together.

It's not the most beautiful thing in the world, but I think we've got a good seal here.

http://forums.pelicanparts.com/uploa...1364952651.jpg

As extra re-assurance, I will be tracing my seam line with RTV black to ensure that we do not have an air leak.

In hind sight, I think that I might have been better off going new with this airbox, but at more than twice the cost - the jury is still out.

CIS progress
 

Because I am working in uncharted territory, I am likely going to have some questions in these stages of the re-assy. When I got the motor, the CIS was not attached, and I have to rely on the images of other pelican-ers as well as some of the images I have found elsewhere to determine where some of the vacuum lines and various hoses are supposed to connect.


That said, I was able to put a little time into putting new hoses on the recently re-assembled airbox.

http://forums.pelicanparts.com/uploa...1365126397.jpg

I don't really have a bunch of time to work on it till Sunday, where I hope to attach the runners, fuel injectors and the CIS to the engine.

I think that we're nearing the home stretch!

Coil wires?
 

Hey all:

I put a couple more hours into her again today: the task was to install the CIS/intake - as far as I could before I was done for today.

The CIS install was a little more of a task than I originally estimated. I pity the fool who will attempt a CIS removal with the engine in the car.

http://forums.pelicanparts.com/uploa...1365375271.jpg

As I suspected, I have some questions regarding the miscellaneous wire connections. As stated above, I received the engine with the CIS disconnected, so I am in uncharted territory to complete this job (finally).

Anyone have an answer on this:
http://forums.pelicanparts.com/uploa...1365375363.jpg

The large gage RED wire - I believe to be the "hot" line to the starter.

However, we have 3 other wires, and I *think* they go to the ignition coil.
Brown
Brown with white stripe
White

Which ones go to the coil?

Anyone who's done this before may remember, or another person who has a 79SC may be nice enough to pop out to the garage (to take a look at their coil) to provide some input - - I'd really appreciate it.

Wire connections
 

OK:

So I am trying to put the wires in the correct spot(s) - and the coil being the first one - has me slightly stumped.....

My "workshop" manual says I should have a brown/red going to the B terminal. White going to the A terminal.






http://forums.pelicanparts.com/uploa...1365553839.jpg

A different manual says that I should have brown going to the B terminal, and ??? going to the A terminal.


http://forums.pelicanparts.com/uploa...1365553932.jpg

Geeee whiz... - I am thinking that I have an obsolete wire diagram; an incorrect wire harness, or I am seeing wrong colors somehow.

The "gage appropriate" wires lead me to believe that I should be using White to the A terminal and Brown with white stripe to the B terminal: am I going nuts here?

http://forums.pelicanparts.com/porsche-911-technical-forum/472550-coil-wiring-help-please.html
The red is the battery cable to starter as you said. Also the small yellow wires go to starter. Can`t remember which go top or bottom. I just connected them as they layed down naturally as i installed the wiring harness.

Hope that helps abit :)

Oheggem -

Thank you for that. So - for sure we're looking at WHITE on the A terminal - but what's frustrating is that I don't have a brown/red wire available on my harness - but the Brown/White one is there ready for action!

Fuel drained
 

Well, the gas in the tank was a little old (nearly a decade) so - last night - I swapped a favor with a neighbor/friend and we were able to drain nearly 10 gallons of gas from the system. (I hope the leaf-blower likes aged premium...)

As a "while I'm in there" - I figured that I could replace the fuel filter as well as the "accumulator". I got sticker shock on the price of the accumulator, so that will not be replaced.

Here's an easy question: Is there any trick to opening the gas cap as if I were at the gas station? I know, lefty loosey - but it feels like there is a lock there that I am missing.

The brown wire goes to the bolts that hold the coil down and is a ground. The white and brown/white go to the coil - the other ends of that pair connect to the CD box and you should be able to trace them and and use a continuity tester to find the ends that connect and there is a diagram on the box that will allow you to figure which is which..

K Sykes:

Thank you. I will take a look at the CD box and bust out my multimeter to do a continutity test (...why didn't I think of that before!).

Cool.

Transmission mount broken
 

Well, frustration was the result this evening, as I got a few steps further in determine where wire connections go, and I pulled the trans so that I could attach it to the engine. One thing is for sure, this slope got rather slippery quickly.

I was looking at the trans support, and there is a massive crack in it. I don't believe that this (crack) is supposed to be there...

Gonna have to buy another one of those... (shuffling off to the classifieds section).

I need to ask a question at this point to the forum: CV shafts --- is there any suggested care I should take with these CV shafts? Should I get them re-worked by a professional "while I'm in there"? They look fine, but dirty. Shouldn't they have a little crimping connection so that the boot does not fall off?







http://forums.pelicanparts.com/uploa...1367982360.jpg

I would clean and repack the inner cv's while you're there if they're dirty and replace the boots if they're weathered or cracked. I've found remanufactured axles can be of far lower quality than OEM even with a ton of miles on the OEM.

As for the trans support brace - if you can find a good example used then that might be a good idea. You could also clean and weld/repair what you have if you're trying to stay on budget.
