Need help with EBPV...

Was poking around the engine valley to check on bunch work I did early this year (turbo pedestal etc) and noticed the EBVP piston rod was not connected to the door/flapper/valve. I changed it with complete pedestal and EBPV solenoid etc unit from Diesel O Rings.

The clip had disconnected from the arm. The arm must be pulling too far inwards and pulled the clip off of the flapper arm connection.







In my many attempts to get it back on, I lost the clip. OF course.

Until I get my hands on a new clip, should I use some mechanic's wire to tie the flapper open? In other words pull it out towards the passenger side (the position its in, in the pic below)?





They give you some lousy instruction on how to set the tension on the spring and set the length but maybe I didnt do it correctly.



Here is flapper arm I'm talking about:

I lost that clip too. I can still hear the fading twiiiing as it shifted into another dimension.

Auto part stores have a Dorman Help! pack of assorted linkage clips. You want one of the round ones.

On edit: never tried it but I'd expect if the valve is not controlled by the rod the exhaust flow will hold the valve open.

It would probably be fine not wired, but the thought of it flapping around in there while I drove would drive me more crazy than normal so I'd probably wire it open.

I would disconnect the electrical connection to the control solenoid. I wouldn’t want the piston and arm to be all *****-nilly moving around without being connected.

The other dimension being the top of the transmission... In my case.i think.

They sell those clips for $30 on eBay! Stupid.

This set?

Thing is I'm not sure which way is open vs closed and so I'm not sure which position to wire it.

I think that open position is where I have it in the picture with the flapper arm pulled towards the front of the motor or passenger.

​​​​​When the engine is off, key off, and engine cold, is the solenoid in the closed position?

If you do get a SES it shouldn’t impact the driving of the truck. I’d rather have the temporary SES than drive with the solenoid moving the disconnected arm. But that’s just me.
One curveball could be related to having an SES stored for smog testing etc if that’s a concern in your area.

Apparently it's been like that for some time .. disconnected.

How does that clip even stay on the arm.. is just friction. If the arm or the flapper linkage connection point got greasy it could slide off...

I think part # BK7352640 at NAPA should work.

Dorman Kit 41017 Carburetor linkage clips didnt work. Too small.

They didnt have 41016 for linkages at the Autozone near me and I aint driving all over God's creation for a clip when Amazon exists.

Do I have this correct? I'm obviously lying on the motor with my hand reach back towards the firewall.

If I remember it should have a little nub that gets tight as it's going over the shaft. Then once it's over the hump it can't slide bake without a little force.
