as for needing to change the rear ones all out, not really sure or not. i would spend a little time testing them out and seeing if something doesnt work. in the case of clarkes, they leaked. we pressurized the system and i sprayed windex on them and found a couple that leaked either on the valve body or through the exhaust port. then we replace a couple of them and then a few more leaked when the new ones were holding pressure. at that point clarke decided to just change the rest of them in the rear. his front ones were just fine and were not leaking.

so i would see if they work, then see if they leak and go from there. his were very obvious with windex bubbles that they were leaking.

as for rebuilding the manifold, it took me and clarke a couple of hours and that counted alot of chit chat. then another hour or so to put them back in and wire them up.

the obvious key is to take pictures and make sure you label the wires and hoses. i took a picture and put labels on the wires and hoses and then marked them on the printed picture.

it worked first time when we put it back up. looked alot better than before too.

it did require buying a number of fittings that make them go all together. i also use thread sealant that is brush on. it is a mess if as you put it back on and one of the fittings in the middle of it all leaks.

i am pretty fearless and clarke was a bit more skittish, but got the hang of it and i think it helped to get him over the hump of just ripping things apart and fixing it.

so, it is not very difficult.

but it is still 2-300 bucks so i wouldnt do it unless you are pretty sure they are not working right or leaking. but up to you, i replaced a lot of stuff just to start off fresh myself. airleaks are a never ending job. but....on your rig it should be very possible to find and stop them all. you do not have a ton of air powered stuff. i believe on clarkes we found all the leaks, but i will let him answer that for himself.
