vacuum test help
Re: vacuum test help
Did a little test today with the 2 pipes that go down the front of the engine. As you stand In front of the car, the right one has been blanked off as this one operates the inlet manifold flaps and am I think I'm right in thinking the left one is the supply. I put a vac gauge on thecsupply and on tickover it was holding a constant 0.6bar this increesed when I raised the revs. As soon as I killed the engine this dropped to zero in seconds. I didn't blank the airbox or the exhaust flap pipes as by unplugging the supply to fit the gauge I assume they are out of the loop.
Re: vacuum test help
What you want to do is blank off all other components tied in to the vacuum line your testing the vacuum on and pull a vacuum with the gauge and see if it holds a constant vacuum. If it does you know the vacuum lines are ok. All you need to do then is test the components and solenoids.Starry wrote:Did a little test today with the 2 pipes that go down the front of the engine.

Re: vacuum test help
What I'm going to do is just tee in to the vac system and keep everything still connected up. After I kill the engine I'll see what happens..
Re: vacuum test help
Spoke to MRC and the car is going back to them on the 5th to get hopefully sorted. Fingers crossed its something simple....
