Q:I have 1993 Seville 4.9. I got a new EGR valve but it didn't help. I tested it with vacuum pump, it won't hold pressure at all, same with old one. Is that new EGR valve bad or just different type of EGR that vacuum pump won't work? Thanks!
The first source, pages 20-22, lists all 9 basic types of EGR valves. Not all the types are vacuum operated, but check out #5 and #6 - they behave very differently from each other without a real live exhaust system connected to them.
Q:Not the cold and hot water shut off valves. The one with a tiny handle and it looks like a T. what does it do? should I mess with it?
Hi There I installed a valve with a t-type handle for my refrigerator's ice maker. This is a saddle type valve which is place on a water line and taps into the water inlet . It has a piece of rubber around the needle valve so it will not leak. If there is no plastic or copper line protruding from the line then it should lead to an ice maker. Now I have seen the same type of valve which was placed on the water line and then hooked up to the dishwater. Either way don't mess with it unless it leaks... Why the pipe it is attached too will have to be replaced. Been there done that check out the two links below
