A bus named Grace

[stew 89]

Thanks for this Dawie. Should I go to the guy and say this is what I want him to build : "2L CJ aircooled's points distributor's centrifugal advance is specified as 21- 25 degrees advance at 3400 rpm's. Add 7.5 deg static/ idle speed timing to that for total advance. Vacuum advance 8-12 degs at 200mm Hg."

Even though I have a CU motor?

Im Sorry for all the question Im just trying to rap my head around all this info. I don't think that a OE dizzy would rear its head any time soon.

[Dawie]

The guy might have a Sun distributor machine and might know what he is doing. But after reading what he said about the new fuel and valve burning, he might also not know.

At R1900, that is a chance i would personally not take.

About your compression...if your problem is serious. Before deciding to rush into buying a new set of pistons/sleeves, i would inspect the old ones first. If this happens to be a new quality set in standard size that did only around 10 000 kilos, the sleeves will most probably clean up by honing. Take them to a good automotive machining shop for honing. Then all you need is new pistons and rings. Which will be a fraction of the cost of a complete set.

You see this is my thoughts swell. U fortunately I have not collected the knowledge that would make me immutable. I have vague understandings of the who and why a motor should work but the finer details that come with experience and trial and error as yet I do not possess. I am so tired of people telling me they know what they are doing and know how to fix things and in the end the fruits of there promises never ripen.

This is why I am so grateful for your and Sean and Rui and every one that has given me sound advice.

The barrels are all old ones from different motors that were sort of the same size and have been resized to match the pistons I believe the pistons are the ones that were in the motor when I bought the bus. But to be honest I have know Idea what was swapped and changed and removed when the motor was at Valks Engine Change. I think that if I replace the barrels and pistons with new ones at least i know that what I am putting in should stand the test of time.

Is this bay any chance what I am looking for?

[Dawie]

What are the part numbers?

VW part number may start with the VW/ Audi logo and: 021 xxx xxx, 022 xxx xxx, 043 xxx xxx, 025 xxx xxx, etc.

Bosch number something like: Bosch logo, then: 0 231 1xx xxx ,or 0 237 0xx xxx, etc

its 0231168005

[Dawie]

Seems 0 231 168 005 is a points distributor from a 76-79 2L kombi? That is according to info on the net. I also have one with that number here in front of me, it has points, and it came from a 78 2L baywindow. The one i have has the old style vacuum unit.

Do you perhaps have a picture of distributor showing the black 3-pin socket were the plug for the hall sensor fits?

[stew 89]

Hi Dawie

Sorry these are the only 2 picks I have. the guy is using it on A 1600 with mechanical ignition.... Go figure...

You wouldn't be willing to let the dizzy go would you?

[sean]

That distributor above is correct for the 2L, it's just before the electronic one was released. Is he not willing to part? Or are you specifically wanting a electronic ignition variety?

[stew 89]

Hi Sean

I'm going to See if I can get it off his hands But I would like a Electronic Ignition. Are there any advantages to Electronic Ignition?

Thanks again.

[Dawie]

So to clear up you are looking for an electronic distributor system from a 1980- 1982 air-cooled 2L "CU engine" box- shape kombi. You also need the wiring loom with the plug that fits the distributor and the plug that fits the module.

Then you do not want part 0231168005 as this should be the same as the points distributor that originally came with 76-79 2L baywindow kombis. In fact this is what you already should have on your engine?

[stew 89]

Hey Dawie what I have is looks more like a beetle dizzy with the small vacume canister and no retard function.

I'm looking for anything the is more original then what I have. I think I will try get the points dizzy pictured for now until a electronic unit comes up.

[Dawie]

The correct distributor for a baywindow 2l indeed has the small single advance vacuum can and is similar to the 70's beetle one. USA models had a different dual vacuum can.

The distributor on your picture either had it's single vacuum unit replaced at some stage with a dual type, or it's from an overseas model. It's no better than the one that originally came with your car. Do'nt waste money on it.

Only purpose of dual vacuum unit's retard function is to reduce nox emissions as required by some overseas countries. This retarded timing at idle unfortunately also causes the engine to run poorly and hot and waste fuel. I would not connect the retard function as it's not required in SA.

[stew 89]

Oh ok so then I don't have the wrong dizzy on my bus. Then I will just wait till electronic unit becomes available.

Thanks again for all your help.

So Here are some picks of spark plugs....

1st is from Cylender 1 and the second is from Cylender 3

What do they tell me about the state of my combustion? I have no Idea.... what do you guys think?
