In a few weeks, im going to -attack- this Vacuum Leak problem! -SOMEWHERE- it is leaking. My Iron Duke 2.5L Tech4 (1991 Calais, Oldsmobile) has a Looping Idle, especially after warmed up in about 5 minutes or so.. no “Idle Valve.” I have NO IDEA where the “Intake Manifold Gasket” is; I know from a Ford Escort i used to have if THAT has a leak, thats the Vacuum leak right there.. should i buy Starter Fluid and Spray all over the place to see if i hear it rev up? Also, does PCV Valve have anything to do with this? I also have NO IDEA where PCV Valve is, but we thought it may have something to so with it…
But really, where and how and how much of each “Vacuum Hose” or “Vacuum Tubing” should i get, and where do i get these Tubings? And is there a “TooL” to measuee it somehow?
Thanks…

Binky, my friend, you’ve been asking about this car for a few days now. Yesterday you were asking how to take out the thermostat because you “thought” that might be the problem.
You don’t know about cars, take it to someone who does know cars.
Really, if you don’t know that you buy vacuum hoses by the size and by the length at any parts store you shouldn’t be under the hood touching anything.
Any auto parts stores have vacuum lines. Sometimes there is left over lenght of line you can get real cheap. Doesn’t hurt to ask.
Hey fella, before you start throwing parts at it and spraying a highly explosive fluid near an ignition source, it wouldn’t be a bad idea to take the car to a good mechanic with the proper training and tools to diagnose and repair it.
auto zone sells them. just show them what size you need and how many feet. cut a small piece off and show them the size.
Binky:
It sounds as if you are finding out (slowly), that building a car one piece at a time will cost you in …
Money
Time
Labor
A “Dozen” times more than one already in working order.
It’s a hobby for the “well to do”, and naive “shade tree mechanics”.
As well, it should only be performed on Classics.
If you’re doing all this on a unitized body, that’s either rusted or bent, you’re building an inefficient generator.
From your questions, you have a long way to go before you’re road worthy.
Carry on if you wish, but prepare for disappointment.
We’ve all been there. You never get your money back in usage or re-sale.
