I have a 90 T2 that has had all emissions removed, now i just noticed that were the air pump used to be is just a hole. No block off plate. There is just a spot next to the water line for the turbo thats open. Now I dont remember if its supposed to be like that, or if there was a plate and it came off. Someone want to help me remember? Thanks alot.
