 Posted: Sun Dec 27, 2020 2:07 pm Post subject: Couple questions about a DJ tune-up |
 |
|
Hello all. Some questions for you Doka owners. I have an '89 Syncro Doka that I purchased a month or so ago. Imported some years ago from Germany. It has always run like crap- missing, no power, general poor performance. Working thru the list of things to do and have new fuel lines, new filter, working on cleaning the grounds.
Like the fool I am at times I ordered a GoWesty tuneup kit that, of course, included few things I can use. I've read about the DJ engines but have more questions than answers. Would like to do the plugs, wires, rotor.
First. how to verify it's a DJ engine? If so I have the plugs needed from another post but the rotor seems different that what is there. Mine is a little loose on the shaft and is a Beru EVL 085 cz which is, oddly enough, not easily obtained in the States. The wires on it KW 216.
So I need to verify the engine type and then see if the ignition parts are correct, or even if there is somewhere in the US that I can order parts? Really don't want to throw parts at it but it seems like it was not maintained well so these things need replaced.
I will still continue working on the list of things to check like fuel pressure, pump, all of it. A little overwhelmed right about now since I haven't been able to get the simple things like a tuneup completed. |

Take a look at the black plastic oil breather tower.
It mounts to the engine block on a square base. At the rear side of the base facing the fanbelts there should be the engine serial number.
The letters "DJ" should be part of the serial number.

Okay, will have a look, thanks for the help. |

It will be here.
This one is a rebuilt engine from some shop in Germany so it's not the VW serial number.

How did your tune up go? Do any other work on the engine? I'm importing a doka with a DJ engine too, and am trying to learn all I can about it. Similar yet different to the MV it seems!

Well, I did the plugs and set the timing which was set to a NA spec engine. Still not sure on the distributor rotor and what is right. I kept the old one but it seems like it has a little play in it. Runs MUCH better but still not great. I've been addressing other issues like fuel lines and pump, still will revisit and try to find out what is correct. There is a Facebook T3 Doka page with a lot of members. I will try it as here a very limited number of owners it seems.
Good luck on the import. I am not sure I would do it again as it's been difficult to get the right info unless you are a real mechanic- and I am not. I can follow directions but I think that's not enough for this truck. You will do better I think.

| What you need to know, assuming it's is fuel injection is whether it is a Digijet or Digifant. Numbers off the distributor body might help as well. |

A "DJ" is easy to ID, it will have a Vac Adv / Ret distributor and an Idle control relay like an MV. It also will not have a 02 sensor.
A DJ is also a Digijet and not a Digfant. I believe the plugs are the same and the cap and wires are the same as a 1.9.

I can send some photos next week if that is helpful. I can also look for the identifying numbers on the block so we can compare. From other samba threads they sound like good engines ~ we'll get them running right!

Yes, indeed. Mine is running okay. One issue is that you don't really know what the PO did, or did not do, correctly. The timing on mine was set the same as a North American Vanagon and was 5 degrees off. That was an easy fix. Another thread here has some useful ingo on the DJ but not verified. If you ask 3 "experts" about plugs and other items you get 3 different answers. Would be nice to have a service manual for the DJ.

The engine is supposed to be running fine, so I'll see what the degree setting is and let you know.
Somehow I have a PDF copy of the AFC/DJ/DF systems maintenance manual with troubleshooting info. Printed 3/87, which seems early for the 112? I've never owned one so have no idea where I got it from, but that is the beauty of Samba surfing late at night for the last 12 years! It's big. PM me an email and I'll see if I can get it to you.

If its a Digijet it likely tunes the same as any Digijet fueled Vanagon engine and may well use all the same tuneup parts. I would suspect that timing it to 28° BTDC @3800+ rpms, with the hoses off and plugged would work fine for it.
