Hello all, I just installed the STM high pressure throttle body shaft seals, and in the install, I pressed the seals with the metal side down, as in the plastic/rubber side was facing outwards. I have read a few guides but they all say to press them with the open end in? isn't the open end the rubber end? I am so confused and I just dont wanna have to pull the TB off a second time, any help would be appriciated.

 

Almost positive that the metal side should be on the outside, 99.9% sure.

 

metal side is supposed to be on the outside. get new ones man, have fun getting those out.

 

Do a boat leak test, if they're sealed, then they're sealed.

 

^^ or this. but they are supposed to go in the other way around.

 

ah, i made a noob mistake, haha ordered a new set this morning. thanks tho for the input man, gotta pull it off again, did the whole thing in under 15 mins but i bet the new ones are gonna be a pain to take off
