clicking from engine
I have had a loud clicking noise coming from under my hood for a week or two now during idle. Its a very loud constant clicking that only goes away when i start moving and continues during idle until i turn the car off. I cant really locate the sound, which is why im not really sure what it is. Let me know if you know anything. Thanks

RE: clicking from engine
Have you done your Timing belt/tensioner yet?? Could be the tensioner on its way out. Better get that checked asap.. Or it could be your cam tensioner on the opposite side on the engine on top under the valve cover.. Or it could be a failing oil pump. If you havent done your timing belt better do that asap. If it is still there, do an engine flush. But if you could pinpoint where the clicking is coming from that would help too. It could be several things... Best to pinpoint exactly where its coming from first.
