I've made and 3D printed a good few parts for my W124s, not many for the W116 yet.

It'd be nice if you could share the model on Thingiverse or maybe Printables from Prusa.

Nice collection! I have a bunch of w116, w126, and e28 parts I need to upload. For now, here's this part at least on Thingiverse:



Quote from: orientrot on 22 June 2022, 03:35 PMVery nice! I can get you pictures of the one from my car if you are interested, or perhaps I should try my hand at it. What CAD program are you using? I know Solidworks and Inventor but haven't used them since graduating because they are expensive.

This was drawn in Sketchup (quick and dirty), but I typically use Fusion 360 for anything more complicated. SolidWorks is great too, but I haven't had access to a licensed copy in several years.

I'd love to see a pic of the real McCoy if you'd post one. I've found line drawings of the w116 holder in various online parts diagrams, but couldn't locate an actual picture. Every photo seems to be taken from a few feet back with the trunk raised and the vertical portion of the lid cuts off the area I'm interested in!

Quote from: UTn_boy on 22 June 2022, 03:43 PMProvided there is no air in the cooling system, Hearing air gurgling in the heater core is indicative of a leaking or blown head gasket. 

How would you recommend to proceed? Any advice would be highly appreciated.

Thanks for the insight, UTn_boy, although that message scares me and probably should ...

The current situation:

- I do not know if the cooling system is air free or not. How to determine that?
- gurgling is heard when accelerating
- Coolant looks like new coolant
- Coolant temp is constant and ok

Will a cylinder compression test identify a blown head gasket, i.e. if the compression test is ok the head gasket is ok?

If you know Inventor, you will feel at home in Fusion 360, which is free for private home use. Not as powerful as Inventor, but does the job.

Well, the old injectors are back out, the new ones refitted but this time using the old injectors' (correct) rubber holders/sleeves.

Refuses to start.

I am at a loss.

So far:
New injectors + new sleeves. No start.
Old injectors + new sleeves. No start.
Old injectors + old sleeves. Start!
New injectors + old sleeves. No start.

The new Bosch injectors are supposed to be the updated version of the originals.

Perfect, thanks!

Maybe the system self-bleed depends on certain valves in HVAC being open/closed? As long as my vacuum system is shot these valves might not be in the right position? The vacuum system is also on my to-do list ... later.

Valve is not leaking, yet, but thanks for the tip!

There should be no ill effects of doing that. That pod is on the HVAC vacuum circuit, which is supplied from a separate reservoir under the front wing. Probably best if you disconnect and plug the vacuum line, and then fix the lever in the closed position.

As for air in the heater core - that's odd as the system should self-bleed.

Also a somewhat related tip: if your valve is leaking (as they tend to), this same heater valve from W201 (much cheaper than this one, as it's all plastic) is an almost 1:1 replacement. Just needs the tiniest of modifications to the part, but not the car. I have one on my car.
