FOR SALE: OM606 Rebuildable OFV with mod'd spring
FOR SALE: OM606 Rebuildable OFV with mod'd spring
I have been rebuilding the OM616 & 617 OFVs (the rebuildable type) -- there's two types of course, so leave it to the engineers.
The OM606, and other applications are not rebuildable. Ergo, I have a limited production run to fill this gap.
These are all new, come with my mod'd spring already installed, and ready to go. Buyer will need to re-use their crush washers.
Here is a picture. Buyers should double check which one they have. One is approximately 1 1/2 inches long, and the other is approximately 2" long.
If you want to buy one, please visit my site: www.dieselfuelinjector.guru The site has a web based platform store.

I have been selling the springs now for a while, close to 1,000, and always two thumbs up.

However, I've been looking thru the forums where this is posted, trying to find any sort of numbers/testing/results and haven't found anything.
What is different about it compared to OEM other than rebuild-able? You have a "performance" spring, but seem to intentionally avoid mentioning any real details. It's not like you have to give the exact part number for the spring used, but giving some details about how/why it's a "performance" part is pretty standard practice.
The OEM spring at this point is 20-30+ years old and could have 300,000+ miles on it. It seems likely that they are at least a little tired and not performing at 100%. Even if your part is simply a high quality, rebuildable version of the stock valve it would be worth every penny.
As you have mentioned, my fuel pressure gauge will tell me what pressure the valve runs at 5 seconds after I turn on the car. Why not just tell me what it's going to be? I'm running an electric lift pump that is only rated for 20-30 psi. After some searching I found one user who saw ~36psi with the new valve. If that is what I could expect on my pump, then it would be a problem for me since my electric lift pump isn't rated for that pressure.
If everything else is working well, then simply increasing the pressure at the injection pump from 15 to 35psi should have absolutely no effect on the output of the pump. You could increase the pressure to 1000psi and it wouldn't get any more fuel into the pump.
I don't doubt that people feel a difference after installing the valve, but I think you could easily sell a valve to every single old mercedes diesel owner if you could actually explain why they can expect to see a performance improvement. Maybe the old valves are often worn out and under load the pressure gets very low. Maybe worn out lift pumps struggle to keep up with flow rates and the higher pressure gives them a little more headroom. Maybe the higher pressure helps clear out air in the system more easily.
Anyone capable of machining this part, calculating/measuring spring force, buying an assortment of springs, and testing until they found one that worked is going to know that simply paying $50 is the obviously better solution....
If the OEM valve is worn out, then I imagine a $50 replacement is probably cheaper than OEM and rebuild-able is always nice.

Per a bunch of threads the fuel pressure is enhanced. This was covered a year or two ago

And around a half dozen whole OFV rebuildable OFVs for the OM606 engine. Your engine probably never came with a rebuildable one.
There are threads over on peachparts if you're interested.

I still have a handful of these springs left for the rebuildable OFV for the OM616 and OM617 family of engines.
