I have a 2000 jeep grand cherokee v8 4.7L it has a stuck valve making knocking noises my question is can i still drive it !? or is too dangerous
its only really dangerous to the engine , but possibly you if it quits at a dangerous location this sounds more like something else than a ''stuck'' valve . and personally i would not trust it until you take a further look into the engine and remove a valve cover to see what is causing the problem .
For 1 how do you know it has a stuck valve , if you know that you know how to get it unstuck (pb-blaster ) or something like that , or is it carbon holding it open if it is you will need to pull the head becouse the head of the valve will come off and damage the piston and the block , good luck.30 years exp on cars and big trucks
