Porsche 924 Scheiße - back on the road, for now...

[Rusty_Rocket]

Good luck with this car ND.  I also own a 924...

And it has these...

 

Which I can confirm, are also a total pain in the arse, for no gain whatsoever and worse fuel economy.

Keep at it!!

Brilliant, thank you.

The positivity and humour here keeps me going 😎

With the caveat that I know absolutely fuck all about anything and lack even the ability to search this forum. Can anyone else remember a contributor who some years ago, posted a detailed description of his kjet re-build. Including the modification at the end when he put a dent in something with a big hammer to allow something else to move further than designed?

I saw those trumpets and thought exactly the same.

Any videos?

Remaking of the £100 pipe in progress:

Total cost so far - £2.69 for another two pipe clips.

Cheapo Screwfix pipe bender works a treat! Needn't have worried about using 8mm pipe - the pipe out of the accumulator is that diameter anyway.

Completed pipe now ready to re-fit:

All fixed in place now and no leaks.

Car starts first time.

Pressure sinks when warm, same as before, but it does seem to start fine 🤷‍♂️

Going to get it back on its wheels and see how things go...

That’s great - hopefully you can get a few miles on it now and enjoy it, to give you the desire to get stuck in if the issue resurfaces!

There are only a few things that really cause headaches with K-Jet.  Disuse, vacuum leaks, and being meddled with.  Ethanol I'm sure now adds more excitement to the mix which will likely require a bunch of additional hoses and o-rings to be changed that otherwise would be fine for the next 30 years.  I blame that on the twats who decided to stick ethanol in all our fuel though rather than the system.

Keep your chin up and keep at it.  You'll get there, and once the bugs are worked out it'll probably be something which aside from occasionally cleaning the flap on the metering unit won't ever need attention again.  I know getting there though can feel frustrating as it's a lot of little bits that need a lot of dismantling to get to - but you'll get there.

If you've got a good hydraulics place near you they should be able to make up a new fuel line for you for reasonable money using the old one as a template.

Seems to be running OK, so I've had a few cautious laps around the block in the rain:

Re-starts instantly. I have no idea why or how.

The WUR I fitted looks like it's out of a Volvo (amongst other things) originally: https://www.deloreango.com/en/volvo-control-pressure-regulator-warm-up-regulator.html

I think the pipe on the back is just a vent. No great consensus on the net, and it seems to work.

Do not, under any circumstances, question this. If you do you will anger the gods. And then the problems will return. Good news though pal 👍

Twin choke side draught Webers are the work of the devil. Or something. Even the noise gets on your tits after a while. God invented SUs for a reason.

 

(Lovely looking car tho @Rusty_Rocket. Ignore me. Im bitter with Webber 🤣)

Stalled out when idling, so I richened the mixture by 1/4 of a turn on the Allen key, which seems to have done the trick.
