Buck531 Posted October 14, 2002 Report Share Posted October 14, 2002 Anyone got an idea of what to spray on the engine (while running) so I can attempt to figure out there a vacuum leak is? Or any ideas on where to find it? smile.gif Thanks. [ 14 October 2002, 04:28 PM: Message edited by: Buck531 ] Quote Link to comment Share on other sites More sharing options...
Hwilli1647545487 Posted October 14, 2002 Report Share Posted October 14, 2002 Carb cleaner, spray it at where the head and the intake manifold meets. You'll have to check the vacuum lines themselves by hand. Quote Link to comment Share on other sites More sharing options...
Berto Posted October 14, 2002 Report Share Posted October 14, 2002 there is "starter fluid" at autozone, its for that. Quote Link to comment Share on other sites More sharing options...
Renner Posted October 14, 2002 Report Share Posted October 14, 2002 Starter fluid is not a good thing to spray onto your engine while it is running or warm. It is way too flamable for that, it will very easily ignite on any hot piece of metal like a heat shield. It is supposed to be used for spraying into the intake to help with starting a hard to start car, hence it's name. The reason it helps is because it is actually more combustible then gasoline, which is exactly why you wouldn't want to coat the outside of your engine with it. Like Howard said, intake/carb cleaner works best for finding intake gasket leaks, it is way less volatile then starting fluid, but you do still need to be careful with where you spray it. If the car is at idle, you will hear the idle dip if you spray a spot that has a leak. Quote Link to comment Share on other sites More sharing options...
Buck531 Posted October 14, 2002 Author Report Share Posted October 14, 2002 Thanks. I'll spray it around the intake tomorrow and see what happens. I just changed the plugs/wires and PCV valve. It runs a little better when I'm getting on it, but still idles a little rough. Not as smooth as it should be. Quote Link to comment Share on other sites More sharing options...

Buck531 Posted October 14, 2002 Author Report Share Posted October 14, 2002 Well, anyone care to let me borrow one? I really don't want to spend $40 at autozone (yes, I know Jegs has one for $20), but I don't want to spend money on something I won't be using for more than a few minutes or what not. I would appreciate it if someone would let me borrow one though. Quote Link to comment Share on other sites More sharing options...
