i just bought a 94 h22a1 swap off a friend who had it in a 95 civic ex. he took the motor out b/c the clutch was slipping. the motor set on the garage floor with the tranny ripped off and not to much oil in the motor for about 6-8 months. i bought the motor put a clutch in and changed a few things and now the motor has a knocking that it didnt have before. the only things we changed were, replace injectors from stock 1.6 to stock 2.2 and wire the knock sensor which was not wired on the previous car. any help would be great.
