Okay Im trying to install my probe for my greddy egt and I have the tap all done and what not, however there are 4 pieces, the peice that screws into the manifold, the small "washer/sealer" that go's inside, the top nut, and the probe itself. now the small "washer/sealer" is to small to slide on to the top part of the probe. so am I supposed to force it on to the upper part, cuz if I don't the probe wont go all the way in, plus it just slides in and out, so Im assuming if I leave it like that the preassure will just pop the probe right out of the manifold. however I don't want to force it on until I know Im supposed to, cuz I dun wanna ruin anything. any help would be great.
