FreshPrince can you give us an update on the fix? still working?
I ended up using JB Weld when I epoxied my VIAS last year. If you decide to go that route, use the original JB and not quick weld. It cures to a higher tensile strength and make sure you let the epoxy cure before you start the truck up. Haven't had any issues and I haven't had the VIAS rattle since.Neat write up, and were it not for my reluctance to drilling into something I know nothing about, I’d have done it already.
But... does anyone know of any other epoxy that can be used in place of the 3M scotch weld DP-190 that the TSB calls for?
For instance, JB Weld is infinitely more accessible and in my very humble experience has worked wonders for... epoxying stuff.
I’ve got the front timing chain cover pulled off of my X this weekend, figured I’d do some gluing while I’m in there.
About to tackle this myself one of these evenings after work and curious if this is glued in the housing? If it is, I'd almost say its worth it to just do drill and bolt method in post one.So I’ve been thing to do this on my 05 X SE. I got the four screws out of the VIAS housing as per the TSB... BUT... It just won’t come out! It’s like it’s glued in there and I don’t want to put too much force on it and end up braking off the actuator or something expensive. Any ideas? Hoses were all detached and the air induction bracket removed for clearance.

This may be a stupid question.
I understand following the TSB essentially bonds the Vias control solenoid to the intake manifold.
In addition, it's come to my understanding that most of the Xterra/Frontiers which develop this problem have more than a few miles on their engines.
With this in mind, I ask why would you wish to permanently affix a used part with potential wear onto your intake?
Has anyone attempted to fix this problem by installing a new Vias control solenoid?
If the rattle continues, you could always follow the directions from the TSB, but you would be using a new part with hopefully a longer life.
Ps: you can order 3M Scotch Weld DP190 from
I did this. Rattle went immediately away.Has anyone attempted to fix this problem by installing a new Vias control solenoid?
I did the TSB and used the 3M DP-190 adhesive epoxy. I work in the sign industry and use these types of adhesives. I would think the use of the specific 3M DP-190 gray (vs the DP-190 clear which has a slightly different set of specs) has a lot to do with temperature range and with its ability to “stretch” which ultimately means vibration resistance. The 3M DP-190 has a handling time of about 6-10 hours depending on ambient temps. It also has a full cure time of 7 days and slightly strengthens over a period of a few months. If you only wait the two hours that Nissan says, the adhesive will still be a toothpaste consistency.I did it the other day with JB weld. It significantly reduced the rattle but it is still there. I might drill into the valve like the original post did. Has anyone else tried it?
Just received the new valve today and after reading this thread I expect the noise to come back shortly after installing the new one …lol waste of 60 bucksidk how, but i found myself reading this thread again.
I'd like to report that since i did the fix per the tsb, It has not returned.
