CSV Leaks

[RonDwyer]

Well, it was either take forever to start, or possibly leaky CSV issues.   Mine has certainly decided it wants to be a leaker not so long after I got the nozzles cleared.  Starts easily, runs like hell now.  Fuel definitely drips out the portal with the screw off and just the fuel pump running.  Are there any options for getting this valve back into operating condition?   I am told the kits are NLA...Any ideas on leaky valves here?

I have had success with using lapping compound on the pintle and seat. Steady pressure while spinning the pintle. You can also add a stiffer/new spring as they do loose their tension over time. Just not so stiff as to keep the solenoid from doing its job.
You can even install a small o-ring over the sealing surface of the pintle. It works well but have never tested for how long.

How did you manage to hold on to the pintle while doing this?  I like where this is going as the assembly did not look bad.  The spring was not something I thought about.

To access and remove the pintle, you need to remove the fuel line and fitting from the bottom. Then the pintle and spring can be removed. Put some compound on the mating surface of the pintle and put it back in the housing. Use long needle nose or even tweezers to spin it. It is definately easier to do off the car so you can see what your doing. The little package of red polishing paste that comes in "dremmel" tool bits works great.

My CSV was leaking and the lapping trick fixed it. To spin the pintle I attached a small piece of flexible rubber tubing to its back end (where spring seats), chucked the tubing in a power drill and spun it in its seat with metal polishing compound while applying light pressure. Worked great!

I think the main thing to remember here is that less is more. Just a light touch is often all you need.

I am going to try just enough pressure spinning the hose between my palms, I like the hose trick.  Just need to find a tighter spring now.

I managed to fix it with a little tighter spring from the hardware store and lapping with some valve lapping compound.  Now on to adjust the WRD.
I have 5 extra springs if anyone needs one

I used a short piece of rubber that fitted tight on the pintle, applied Silvo and spun it in the drill several times whilst pushing in and out.  Take a strong magnifying glass and inspect the pintle and seat. When it's perfect reassemble it.  Pull the spring longer.  When you've got it right it shouldn't leak a drop.  I've done a few.

I used a heavier spring C-556 from www.centuryspring.com and it is completely dry now.  5/16 x 5/5 x 0.26
