Delivery valves
 

How much are used non-intercooled delivery valves worth? i just got an 89 and think thats what the problem is and my buddy has some layin around.

:humm:

They rarely, if ever give any problems. If you've turned up the fuel screw and torn the tip off the plunger of the fuel shut-off solenoid, the rubber bits often end up getting hung in the DVs.

Just pull them out, disassemble and clean, then put them back in. :pca1:

Sold a set a while back to a guy who was converting a VE from I/C to Non-I/C to put it on a VP engine (very smart move, IMO) and needed the early valves and holders.

I sold him the set for $60, shipped.

Personally, I'd do as others have said, pull and clean them.

I was gonna clean them anyway lol. I only paid 30 buck for them.

Btw, could that be the problem? 3 and 4 dont have the same pressure when you crack the lines loose at the injector?

Won't know till you pull them and see. ;)

In over five years of surfing the major Dodge/Cummins forums, I can't think of one instance that I've read about VE delivery-valves being of concern (other than FSS rubber bits being in them). :pca1:

Very true, i just dont understand what the deal is with it. It only runs on 4 cylinders. 3 and 4 dont have hardly have any pressure at the injectors, just pukes out. :humm:

now I'm concerned...... I lost two of those tips before going to the pull cable, if they make it through the D/V are they at the injector?? if so, when the line is removed would it come out.

The DV is bigger than the injector inlet or even the edge filter on a 1st gen injector.
So, yes, it would go straight to the injector after the DV, if the debris is small enough.

The edge filter, which is a feature on all 1st gen injectors, would save you getting it into the body or tip, which is why they are usually on the VE injectors.
Bosch likely knew there was a potential of this happening.
