therealtrikky Posted October 17, 2011 Posted October 17, 2011 Ok, I bought a 92 sc400 and have been "going through it" I have worked out a lot of the bugs and kinks, have a digital repair manual on the way, but in the meantime. I am trying to figure out the vacuum diagram. I have 2 vacuum lines coming out of the front of the "intake" just under the Lexus logo. The larger of the 2 has a bolt crammed in a short section of hose. Any information as to where this is supposed to go, I sure could use the help! Thanks in advance. New to the forum and look forward to learning even more about these cars!!!!

Mbtech78 Posted June 14, 2019 Posted June 14, 2019 Someone bypassed the valve and didn't want to spend the $3.00 to cap it off
