ok, so heres something interesting. today, while messing with my car, i decided to find a better solution for my emissions removal leaving the vaccum nipples to deal with. so, instead of putting the rubber caps over the nipples, i have a super easy solution. i had bought some new allen screws for my CAS cover, and had about 40 extra ones laying around, and by a whim, found them to be the perfect size. with the purchase of a tap (size 4x0.7 i believe) the allen bolts go right in the the UIM nipples.
so, i figured id put that up in case anyone is randomly searching for a better solution (reason being, at about 20psi, the caps start to FLY off of the intake...and the allen bolts will stay in place much better, being threded into place!)

initial D is REAL!

you used a 4mm with .7 thread pitch? So I guess you took off the upper manifold to do this? Not a bad idea. I was thinking about taking out hte metal nipple and welding over it, but it woulda taken some time

yeah, i was replacing a turbo part, and just had the upper manifold sitting out, so i figured id do something about the caps. it only took about 30 minutes to do, and looks way cleaner/safer than those caps. ill think about getting some pics with my phone later..

I might do this too. Not a bad idea. I hope I have that tap

Hmm... 20 psi you say? I'm running a stock 13bt with emmisions removed and banjo bolt mod and it keeps blowing the vac caps off.... Good info though, looks like I may be doing this.
