I undertook the task of changing the valve cover gaskets and spark plugs on my v6 runner yesterday. FUN FUN! I was surprised at the amount of vac lines on the thing. I am wondering if anyone knows ways to eliminate most of these lines so i can clean up the engine bay?

 

NO, they all serve a purpose and designed for a reason. Mess with those lines and you will regret it. Cross them up and you will regret it. Take the time to mark (label) them and draw diagrams as to where they connect.

You have been warned.

 

There is a diagram under the hood that is a vacuum diagram.

Yes you do need all of them.

 

Thanx again
