You cannot weld something on.

I thought you could weld the mag cases? Isn't the space behind number 3 cylinder welded on mag cases sometimes?

This isn't the pic I was looking for, but this case was welded.

You can tig it. but with special very expensive tig rod.
My guy that does my heads can do them, but he has not done one for years, and does not like to do them.
It would be hard to find some one that is set up to do them.

I get ya. Definitely not something someone could MIG weld.

some of the expensive MIG welders might be able to do it with special wire and stuff, but I don't know for sure. When I took my welding class, we did go over the different rods available (for TIG) so you can do more exotic metals. I asked my teacher specifically about doing Magnesium cases (he used to be a dubber himself) and the look of horror was enough to crush any ideas I had about fixing up old cases :lol:

you'd have thought he was flashing back to a traumatic war story or something...

I'm going to make an assumption that the FI has been removed, and you're basically looking at a long block in the engine bay. If I'm wrong, then you'll have to remove the FI runners and IAD (Intake Air Distributor), along with the AAR unless you're using a low pressure electric fuel pump, then it can stay where it is.
However since you have a 72, you're going to need to change the breather box, and do something with the ports (short tubes) in the cylinder heads.
Anyway, you'll need a set of carbs, dual port intake manifolds, a fuel pump (mechanical or low pressure electrical), and carb linkage. If you decide to go with a mechanical fuel pump, you'll also need the bakelite spacer, and a fuel pump push rod that matches the pump you buy (try and get it for a generator, as that was what the 67 and earlier cars used).
The choice of carbs will also be yours, as some here prefer the Solex carbs (unfortunately they'll probably need rebuilding), or weber 34 ICT carbs. If you go with the webers, get them as a kit from CB Performance, as they'll be jetted pretty close for your engine, and have a balance tube (it's actually a hose) which our engine like. They'll also come with everything you need to install them, except the fuel pump.

You'll have to remove the stock t-3 electric fuel pump that's located under the fuel tank (usually on the right side of the beam), and route a new fuel line from the tank to the left fuel tube in the pan. Then you can add a fuel filter in the rear along side the trans (or put it under the tank like it was), as I prefer to filter the fuel after it goes thru the tunnel with carb motors. It also makes it easier to change, as you have more room to work. The next thing will be to remove the power wire that goes to the FI relay from the battery. This kills the power to the rest of the FI system that can be left in place, or removed if you want. If the car still has the FI wiring harness still in the car, you'll want to remove it and the ECU, and unplug the 3 or 4 wires that connect it to the car's wiring harness. The rest of the car's wiring can remain just as it is. I hope this helps.

Sil Modesti in Phoenix. But you have to bring your own magnesium rod.

thanks bobnotch!!!!

Mon Mar 29, 2010 3:50 pm

Bob- doesn't he have to also replace the two studs on his case with longer ones so he can mount a mechanical fuel pump?

Also- make sure you change ALL fuel hose on the entire car with new stuff, and use "fuel injection" type hose clamps. Whatever hose is on there is likely to be cracked, or soon to be.

Tue Apr 13, 2010 1:42 pm

the previous fuel lines are toasted becasue the mechanic who replaced them last, instead of using clamps with screws to tighten them on the fittings, used wire and wraped it around the line and twisted it tight like a twist tie hah then it caught on fire.

anyways, i got my wiring harness and now im looking for the 2 fuel injectors on the left side, and im pretty sure thats it, these are the new parts im buying

alt
fuel pump
dist-wires
hoses
belt
thinking about replaxcing the oil pump while i got the motor out
also any suggestions on dropping the motor? i have the haynes

how do the wires that controll the tail lights get back to the tail? where exactly do they run through the car?

Tue Apr 13, 2010 2:05 pm

You have to remove both rear fenders to access the tail light wiring. Don't miss the tiny screw under the hatch rubber.

Wed Apr 14, 2010 6:48 pm

so all my wires burned up, this wiring loom, http://www.jbugs.com/product/WM-311-62-67.html?Category_Code=1290 is this all i need since i already have the engine wiring harness? this loom will work the tail lights?
also i dont really know what its supposed to look like and where things are supposed to go ? i think the coil burned to ash cause i couldnt find it

also- about droping the engine, any tips for removing the engine and keeping the trans held in place?

there are a bunch of little things around the left side of the engine bay what are they? i need them whatever they are

thanks for any help its greatley appriceated, i hope to be on the road soon in this sweet little thing

Welding a VW case is kind of like trying to weld a Molotov cocktail. You'd better have the right equipment, excellent skills, and brass balls.

Mon Apr 19, 2010 10:07 am

heres what i need. i need the wires off of a running engine or i need a diagram to show me what to buy or what wires to make length to cut and where they go

i need the plastic parts mounted on the cars left side of the engine bay or i need to know what they are to order them, i cannot find pics or diagrams to tell me what parts these are can you help?

Mon Apr 19, 2010 10:25 am

PAY JSMskater to build you a New wiring harness and sell you the injectors etc. that you need. :idea:

Wed Apr 21, 2010 11:05 am

what is all that junk on the left side of the engine?

Wed Apr 21, 2010 11:09 am
