help! truck making a ticking sound.
Hello my 72 chevy pickup is making a ticking sound while driving. The faster I go the faster the ticking sounds. When I'm parked I can barely hear it, even while I rev the motor. I think it's coming from my transmission which is a th350. Any suggestions would help, thanks.

Re: help! truck making a ticking sound.
Check U joints in your drive shaft.

Re: help! truck making a ticking sound.
Welcome to the board!
If it's ticking when parked, it won't be u-joints. I'll guess either a collapsed hydraulic lifter, or an exhaust leak at or near the manifold. Could be transmission, I don't know. Another possibility is cracked flex plate. They'll sometimes crack between the bolt holes.

Re: help! truck making a ticking sound.
I was also thinking valves, lifters, or exhaust leak.

Re: help! truck making a ticking sound.
Years ago I had a 350 that ticked. I poured in a bottle of Hyperlube and the tick went away. Its only about $12 bucks to find out. If it does fix the problem then you know its valve train related.

Re: help! truck making a ticking sound.
Sounds like an exhaust leak. It sounds louder while driving because your working the engine. does it go away when you stop accelerating and coast???

Re: help! truck making a ticking sound.
Reach up under the dash and make sure your speedo cable is tight. Do the same thing for the connection at the transmission. Optional - disconnect cable from speedometer, pull through firewall to engine bay, and add some lubrication.

Re: help! truck making a ticking sound.
I believe it was an exhaust leak. When I unmounted the driver side exhaust from the header I found that the gasket was broken. I've since then, had hooker headers and flowmaster 44's installed. Gettin' her ready for summer. (*o*)/
Thanks guys, sorry about the lateness of this post. I've been busy with school and work. Cheers! |
