Having problems with your Mazda Cars & Trucks ?
If a valve does not close completely will that keep engine from starting
It would really depend on the amount of cylinders you have and how far it stays open. Say it's a 4 cylinder engine with the valve staying open quite a bit. That WOULD cause you to lose a lot of compression. If you have say a 6 or 8 cylunder, you may have a poor running and missing engine but the compression would most likely be made up with the other cylinders. This isn't a for sure thing as different engines require different amounts of compression in order to run but hoping you get the concept of what I am trying to say. Hope this helps....
