It's easier (and cheaper) to find a used one that works than buy a new and expensive one. Point is that on 924 NA you can use a WUR from whatever car that uses CIS (Ford, Audis, BMW etc). They're the same thing.

I've seen a couple different styles. One has a vaccum port (for the 931 I think and maybe for the early 928's) and others don't. You'll want to be sure you're getting the right one for the 924. I think the vaccum is for extra enrichment at WOT. It's in the Probst book, which I don't have at hand right now.

I bought a rebuilt one from Perf. Prod. for about $76 or so, with their 10% discount, which I think they're running right now. I remember it was so cheap, I bought two, both rebuilt. But the core charge is around $90 also. Napa also sells one, Echlin brand I believe. It was around $109, also rebuilt, I believe. If you call Perf. Prod. or Tweeks (Mid America Motors?) they'll give you a current price and possibly a discount from the catalog/web price. They did for me anyway. I didn't ask for it, they just took 10% off so I must have hit Perf. Prod. while they were having a sale.

I don't have any complaints about them. It fixed my fuel pressure problems. But the only way you can know for sure it's working or not is to have the CIS gauges hooked up.

A local Bosch dealer had them for about $189 new. He recommended I buy the rebuilt so I did.

*Edit* BTW, when I opened up my old one, I couldn't find anything to repair on it. There's not much that can go wrong but something did. I just couldn't figure out what it was. Couple others have tried to fix them with limited success.

Only thing that can break in WUR, is that the wire doesn't heat the bimetallic strip anymore and thats it. You open it up, apply 12V to it and touch it, if it heats, then it works.

Yes, there are two kinds, with or without vacuum, I referred to that one without.

That's not the only thing, that wire helps to heat the unit to get the fuel pressure to the 'warm' setting, however, if it has an open the heat from the engine will get you there(just not as quick). I recently had a failure of the WUR, it would NEVER get to the warm spec and the heating element was fine. Another WUR cured the problem.

When I bench tested mine, it would heat up and you could see the strip moving the spring but it still wouldn't flow to the correct pressure. I checked for flow through the ports, too. No satisfactory results. Only fix was to replace it.

Raceboy, have you found a way to test these that can result in figuring out a way to rebuild the component?

A used one is certainly cheaper but I would still recommend a rebuilt over a used. Better odds of success.

IMO only thing that is rebuildable in it, is to rewire it or the bimetallic strip is tired. There's no more "moving" parts. Of course, there may be dirt in the filter-like thing too.

After replacing my WUR with a new one ($200), I took the old one apart to see how it worked and what went wrong.

The problem was that the valve has rusted up. There is a steel disc with the fuel-line connections on it. It has a very small pin hole which gets covered by a tiny steel puck (under pressure from the bimetallic strip). The 'puck' had rusted to the disc so it wouldn't move.

If I was keen, I'm sure all the parts could be cleaned up and the WUR would work like new (if I hadn't lost the screws ). Same must be true of reconditioned ones where at least some of the components are renewed.

Sorry Mike but ... where did you buy a new WUR for only U$S 200?
I can´t find new ones, only rebuilt for 184 dollars

http://www.napaonline.com/cgi-bin/ncommerce3/ExecMacro/NAPAonline/search_results_kw.d2w/report?ENG=8%7C2.0+L+1985+CC+L4&search_string=Fuel+Warm-Up+Regulator&org_string=regulator

In case the link doesn't work:

NapaOnLine.com....$112 for Echlin brand w/no core charge listed. Don't know if that's new or rebuilt.

NapaOnLine.com....Beck-Arnley for $98. $20 core charge. Again, doesn't say new or rebuilt but I'd bet rebuilt.


Don't know instock position though. Call them.....Do you have Napa where you live? You can order off the web, too.

If the link doesn't work, go to NapaOnLine.com and search by listing your make, model and year and then search for "regulator". That's what I came up with.
BTW, I'm amazed at Perf. Products pricing...jumped over $100 since I bought mine 3 months ago. Unless I got a less-than-attentive salesperson.

So, my motor is still out, and right now it's super easy to get to my WUR. Should I just replace it with one now? If my car was hard to start before, and it idled rough, would this be a problem? How often are these the source of problems?

Thanks,
-Jonathan

Are you sure it's the WUR, Jon?

When mine wasn't working:
1) the car always started OK,
2) the car always idled OK,
3) it would try and die when you pulled away or put your foot down until it had warmed up for a couple of miles.

I just mention this because it doesn't sound like you're having the same kind of trouble.

Finally I bought a new WUR and new injectors when I went at the factory in Züffenhausen Germany total cost: WUR 355 euros and each injector 56 euros. (all brand new off course)

At today's rate of exchange:

355EU = $425

56EU = $67
