mikeshoup Posted April 16, 2006 Share Posted April 16, 2006 Okay, ever since I bought this XT Turbo from phil, its had this boost leak sound to it. When the boost turns on, you hear a fluttering... so I was searching for any vacuum lines that look cracked, broken, missing, etc... So, I found this little assembly in the attached picture. It has two vacuum lines running up to it (I don't know where they come from), and the one end looks like both have been plugged. Well, the one rubber plug has a hole in it. 1. What the heck are these two things? 2. Could this be the source of my boost leak? 3. Should I just plug off the open ends (since the one's plug has a hole in it...)?

DrKrazy Posted April 16, 2006 Share Posted April 16, 2006 Pretty sure those are for your 4wd, well at least I think so. Think they control the Diff-Lock on my RX so pretty sure it would be for your 4wd. Therefore guessing that yes it would be your boost leak. Does your 4wd work?

mikeshoup Posted April 17, 2006 Author Share Posted April 17, 2006 You're right, that's for the 4WD switch. 4WD does work. On the opposite end of where the vacuum lines go in, there's two more fittings. It looks like they've been tried to be plugged (one of the plugs has a hole in it). Should these be plugged?
