IDI Engine / Re: Please help me get my JX 1.6TD running!

« Last post by ghostrider2 on Today at 12:28:06 am »

Here's the photos and videos as promised now:

Here is a photo of the injector pump timing set to 0.9:

Here's a video of the engine running and (you can't see it) but I push the cold start cable in and it stalls out. Please ignore the unfortunately timed air compressor turning on right at the end. You'll also hear my garage mate spraying the compressed air in the background (that's not my motor!)

And here's a video of it running roughly and you can see the bypassed fuel system. Is it curious no fuel is coming out of the return line?

Thanks y'all. That's encouraging because adjusting pump timing is something I know how to do now! 

And, yes, it has a turbo. Just the standard VW version though. Nothing fancy.

I would like to see you bump that pump to 1.25 and see what it does.  Is this an engine with a turbo?  Those should have 155 bar injectors so you can overcome some of the extra pressure that comes with increasing the air into the cylinder.  At the same time, you have increased the pressure and you need to inject the fuel earlier so it will take advantage of the increase and force that piston down sooner and you get the benefit of the extra power. 

That is what I have going in the 1.6 diesel with a turbo on my PU and it seems to do better than if I run a standard 90 or an enhanced 1.05 mm timing.

 I think your instincts are right.
 The cold start lever is a great indicator of how well the timing is set.
I don't think .9 is the recommended setting.
 At least around here it's closer to 1.

Even though they aren't the best place, PartsPlaceInc out of Michigan is probably the only place I think is available to find info on 1.9 IDI engines

Well, it appears my success was short-lived. After 84 views in 5 days, I'm sure someone would have mentioned a parts manual if one existed. Very disappointing.

Hello everyone.

I've spent the last year swapping a 1.6TD JX into my 1981 VW Vanagon (replacing a broken 1.7KY NA Motor). I've swapped everything from a donor vehicle that I test drove shortly before removing the motor and transmission. In the process I replaced most the seals and sensors (aside from the head gasket and injector pump).

It's now finally in my bus, cranks and starts with the cold start pulled all the way out. When I give it gas or push the cold start back in it sputters and dies. Here's what I've checked so far:

• Set the belt timing to TDC
• Set the injection pump timing to 0.9
• Bled the injector lines
• Fed fuel directly into the injector from a clean container to bypass the filter and make sure it wasn't a filter problem
• Checked for power at the solenoid and glow plugs - yes

I have photos and video of the following but can't post them to the forum. I'll update the thread if I get permission.

• A photo of the injector pump timing set to 0.9.
• A video of the engine running and (you can't see it) but I push the cold start cable in and it stalls out. Please ignore the unfortunately timed air compressor turning on right at the end. You'll also hear my garage mate spraying the compressed air in the background (that's not my motor!)
  
• a video of it running roughly and you can see the bypassed fuel system. Is it curious no fuel is coming out of the return line?
  

Only thing I can think of is to advance the pump timing but I don't really want to move it forward from the recommended settings until I've exhausted everything else. Thanks in advance for your help!

Parts get old and worn.  That was the case with my latch.  I did manage to repair it enough to get it to work but I really wanted one in better shape.  Glad I found one.

 I haven't had that one happen in a while.

I seem to remember someone on this forum that has access to some form of exploded view drawings and part #s for the individual pieces but dang if I can remember who that person is
