Everytime my truck is running I hear a tick tick tick coming from under the truck somewhere Please looking for any insight on this problem.

 

Need some info about your truck.
What year?
What model?
How many miles?
Any Mods?

Missed any payments to "Guido" the bookie?.......

 

What year is your truck? When mine was making that noise it almost drove me crazy, until I figured out that it was the mechanical lift pump, on the driver side back of the engine under the fuel filter.

 

He has a '95.
It could be the lift pump or the overflow valve or it could be normal. Use a long screwdriver or piece of pipe up to your ear and see if you can trace the source.

 

hey guys thanks helping me with this problem my truck is a 1995 Dodge 3/4 ton 2wd diesel any help will be much appreciated this noise is driving me crazy.

 

Had both and one was the overflow, which goes away with increased RPM and the lift pump just ticks faster with more RPM. Both easy fixes once you learn what you are doing. Good luck.

 

Thanks when U increasethe RPM the tick gets faster? What does that mean and how do I fix it?

 

Start with the overflow valve. Does the noise get louder with the temperature?

 

Na it gets louder with increased RPM

 

If it gets faster with RPM and does not go away then it is the lift pump, if it goes away while driving then it is the overflow, I have had this headache. Drive next to a wall or a curb on the driver side and if you can hear the ticking constantly then it is the lift pump. The return spring in the pump goes out and doesnt allow the pump rod to seat on the cam constantly so it "ticks" as the cam slaps the pump rod. If you have any other questions PM me.

Or time to reset the valve lash?

While the truck is idling, if it is ticking, find somthing that you can push down on the fuel primer really hard with and hold pressure on it, most of the time it will stop ticking, "hint, its the lift pump".
