I have a 1997 Ford Explorer and I was told that my valve needed a new lift. I was told that, but was not told what it was. I was told that without the lift for the valve I can still drive the car problem free, but that I should get it taken care of sooner or later. Is there a mechanic in the Yahoo galaxy that can give me some insight? Thanks.
Ok, I assume they told you you needed a new valve lifter! This should not be big deal if they know what they are doing! Valve lifters are in contact with camshaft, and push pushrods up to push rocker arm, - which pushes valve down and open! sIt requires removing the intake manifold and taking out lifter and putting in new one, -- I think it is possible that there is a tool that may actually be able to reach down inside (with valve cover removed)-and pull it out -- after pushrod is removed! I have seen or used these on other engines before, but it depends on what engine you have , -- you might even have an engine with overhead camshaft, in which case it is easy to get to as it is on head!
Does the engine make a clicking, or tapping sound? If so that is a lifter, not a lift. A lifter rides on the cam shaft and has a push rod on it that activates the rocker arm which pushes on the valve. A bad lifter will make noise and ultimately fail. You could damage the engine, at the least it will run poorly. To fix it you have to take apart the top of the engine. Not an easy or cheap fix. If this is not the problem I don't know what you were told. Good luck.
