There is a group of vacuum solenoids(at least that what I think they are) on the inside of the engine bay, near the bulkhead( I have attached a pic) It is making some ticking sounds and I am not sure if it is normal, or if I just noticed it. Can anyone tell me what these are?

Cheers

If it’s a classic truck then I believe they are for the EGR valves

It is a 2003 Warrior.

I think they are the vacuum actuator solenoids.

I will follow this thread mate, mine started clicking a few months back. £15 on EBay, so quick easy fix if they are causing the clicking.

@Marty03 The VGT solenoid to the turbo actuator. Don't bother with a cheap one , go gen Mitzy, the cheap jobs are simply shite, i've gone though 3 in 12 months, even Milners single solenoids aren't gen and mine has never worked properly, the vent cap on the back leaks , another member has had the same issue recently, been meaning to try a quick fix with a dod of something on the steel pipe to seal it, no got round to it yet though.
Sorry this is in reply to your vacuum thingy post.
