New cold start valve for sale?

[Jerrys76]

Does anyone know where I can find a new or refurbished cold start valve? Mine is clogged up and not spraying. I've checked the usual retailers (bus depot, german supply, go westy, etc) and no luck...

Thanks!

You know.....not to highjack this thread.....but here and there we have been discussing the issues we have with this valves.

Granted I mostly work on D-jet.....and out valve is slightly better in some ways and just as bad....and just as hard to find.

The D-jet inje tor can fit the bus engine with very little work but has a different plug. If you are just looking for function and not exact replacement you can use one. I have used a bus unit in D-jet.

The D-jet #s are: 022 906 171 A or 311 906 171 B.

The Bosch 0 280 170 019 is a D-jet style with a dead end fitting is used in some Volvo and BMW but is functionally the same.

All of that said....down the line when none of these are available.....virtually any engine fuel injector of the right flow rating can be used. There are so many brands and sizes....a small injector with a mounting bracket and tip seal could be fabbed up. Ray

You can also look to send out for ultra sonic cleaning. I sent mine out along with a set of injectors to Rich at Cruzin Performance. He was able to improve the cold start injector from a dribble to a solid spray pattern. Right around a $100 for 4 injectors and the CSV with a quick turn time. Notable improvement for sure...

Referencing the post Ray referred to I believe the rabbit valve with the longer nozzle will work as a direct replacement. Just make sure the EGR octopus of piping isn't in your way internally.

issue to note in using a different CSV is that the bus is a "flow thru" meaning a fuel inlet and outlet that goes onto the other fuel rail. Using another valve means T-ing off from the fuel line to that valve. No big deal.
Also, Bus Depot has them listed with a $95 core charge, they are listed as rebuilt, is OP saying they checked and BD has none to send out? On a related note does anyone know who BD uses to "rebuild" these CSVs, as I'm sure you could save a bundle circumventing them in the process. In my other research I came to the same conclusion as another poster to just send it to a rebuilder to have them cleaned and tested.
This is all fresh in my mind as I recently noticed mine leaking and started searching for these. Some tips:
1- search classifieds for FI stuff in general, often you will see a plenum for sale by itself or in a lot for cheap money, considering BD wants $95 in core charge buying a plenum for $30 just to get the CSV isn't a bad deal.
2- WHEN these were still available there were a few part numbers that will show up in an inventory system, used by the big company reboxers. They are as follows:
Bosch: 0280170026
Standard Motor Products: CJ8 (have fun sorting through the Jeep hits you get)
Beck Arnley: 158-0086

---note that these will all (or should) be actual Bosch parts, just reboxed. I found ONE CJ8 on Amazon Canada but can't figure out how to get it sent to America, won't let you enter the US address. At any rate they want like $200 for it.
So if you have contacts with some small scale parts houses, search all the numbers and you might come across something. I tried for about a week on the internet, searching parts sites in many countries, it truly is a no-go at this point sourcing new ones.

Happy hunting.

Do not get hung up in flow rates .The CSV is a crude device. Its just extra fuel. While having too much could be a problem...as long as its not huge and you are spraying for only a few seconds...its not an issue. Having a little too little would not be an issue either.

Other valves to check...were those from almost any fuel injected Datsun like the 280Z and the Nissan 280ZX.

any one look into the saab 900 CSV? believe it had the same design, but dimensions could be off.

Are the L-jet bug CSVs compatible?

Just take the csv and your injectors to your local diesel injection service center and have them cleaned. Should be about $100. They mostly work on highway truck/pickup diesel injectors but were quite happy to do mine. You get a flow report back as well.

I had mine done over 6 years ago and no issues since. Good fuel, ethanol free for the most part, clean tank and regular filter changes = no problems.

NOS ones are rare these days, and used ones can break too. I have nos one but it hasn't been listed for sale and when/if it is, it won't be cheap. They went NLA about 7 or 8 years ago and the off brand boxed ones have disappeared too. The solution I would go with if you need a new one is to use one that has a single inlet like shown, then run a hose to a metal tee, then run off that. It might even be safer because the plastic gets brittle on used ones and sometimes breaks at the top of the CSV burning the bus down.

The Standard Motor Products CJ8 cold start valve was a reboxed Bosch unit and they seemed to have been the last around as old auto parts stores closed in the 2008 recession. Even back then a new one was $75 to $100. The CJ78 valve visually looks close so it might work with a tee but I don't know. That said they are $240 - $250 each. ALl I can say is wanna play gotta pay. These buses aren't cheap anymore. Finding a used one and having it cleaned will work but test the plastic barbs first because if they snap off from age then up goes your bus.

All your CSV dreams and nightmares were discussed in my fire thread....

About page 4 is where it take a lengthy creative turn, unfortunately no conclusive solution was reached for an alternative.
