metal to metal sound... September 05, 2005, 11:03:57 PM on my '84 cougar i'm getting a weird metal ticking moise as I take off. the noise goes with the rpm's pretty much. I also notice that there is a not so loud noice as I'm climbing up a hit. I just did a tune up on in & it doesn't sound like its misfiring. Maybe u-joints? I've crawled under the car and everything looks the way it should. I'm not sure what to do about this. Any ideas? Quote Selected

Reply #1 – September 05, 2005, 11:52:51 PM change your u-joints to start out with. not knowing how many miles they have on them or if they are original. and if it doesnt go away try to listen to where the sound is coming from. does it click when you move the shifter from drive to reverse with the engine running?

Re: metal to metal sound... Reply #4 – September 15, 2005, 01:33:07 PM thanks for the replies. i found out it was the rear u-joint. when I took it out two of the caps were broken around the top. Along with one of the caps pins were completly ground up into a metal powder. kinda scary. Quote Selected
Re: metal to metal sound... Reply #5 – September 15, 2005, 05:05:34 PM If the noise is constant with the RPM's, it's not the u-joints. If it were, the noise would be constant with your speed (the faster you go, the faster the ticking noise). Since it's constant with the RPM's it's probably a lifter ticking in the motor. First thing I would do is check is the oil level - having low oil means that the lifters are not getting the adequate lubrication required for them to function properly. Second: you may want to upgrade to a higher viscosity motor oil - for example if you're running 5w30 now, at your next oil change, put in 10w30 and see if the problem goes away. If it quiets down you probably just have worn out lifters and it's time to replace them. Quote Selected
