baccaruda Posted March 11, 2007 Share Posted March 11, 2007 so I was regrounding the engine bay of the EA81T coupe with 3EAT trans and I found a vacuum hose that went to nowhere... it comes off of the top center of the trans, right above the governor and the hose is about a foot and a half long with a couple of formed bends, roughly 1/4" inner diameter.. I couldn't find it explicitly mentioned in my 84 FSM nor in a search here.. anybody smarter than I am?? thanks! Asny Quote Link to comment Share on other sites More sharing options...
GLCraig Posted March 11, 2007 Share Posted March 11, 2007 IIRC it's a vent hose for the front diff Quote Link to comment Share on other sites More sharing options...

baccaruda Posted March 11, 2007 Author Share Posted March 11, 2007 where's the other end supposed to go? j/k thanks! Quote Link to comment Share on other sites More sharing options...
psylosyfer Posted March 26, 2007 Share Posted March 26, 2007 The other end stays open to allow venting, But originally it would be secured somewhere to keep immobile and not flop around where it shouldn't be, Usually they use a few clamps/ties, And just secure them down the side of the tranny or diff. Secure it anywhere it will be safe from heat/ moving parts and not kinked. Pointing generally downward (my guess is they point them down to help prevent stuff going in). Exact routing is not critical. It's only there to keep pressure equal in and out of the case (from temperature and or altitude changes) this could cause seals to leak/fail. And a hole without the hose would be vulnerable to contamination getting in, or plugging with grime. Quote Link to comment Share on other sites More sharing options...
Caboobaroo Posted March 27, 2007 Share Posted March 27, 2007 Andy, its a 3AT... mechanical 3 speed auto. The 4-speed auto is a 4EAT because its electrically controlled:-p Quote Link to comment Share on other sites More sharing options...

Yup, we tend to follow the K.I.S.S. principals around here;) Quote Link to comment Share on other sites More sharing options...
