My brother is a mechanic, and he said that it just makes a light tick, its normal for all rangers at high miles. He said it wont hurt anything though, my ranger does it too!

I just replaced my cam cover and intake manifold gaskets. The camshaft lobes and lifters all looked good with no weird wear patterns. She is all back together and waaaay faster The noise is still there so I did the stethoscope thing and still could not figure out where it is coming from. It is only on the side of the motor with the injectors so they might be the cause. I am going to try the Seafoam treatment before my oil change to see if it improves.

Maybe your mechanic was right. Check out this link - this guy seems to think it is the manifold also.

Mine moved freely and was not cracked when I changed the gaskets yesterday. Ticking is still there.

Default Mystery solved!

I went to get some Seafoam and put that through the system. In the parking lot, I decided to pull the vacuum line off of the control that goes to the butterflies in the manifold runners. It looks like an EGR valve mounted to the back of the manifold and has a vacuum line and electrical connector on it. The ticking stopped immediately Put the line back on and it slowly came back. Went and did my shopping, came out, and started the truck, ticking was there. Pulled line and it instantly disappeared. I drove that way for about 15 minutes and no ticking was heard at all (engine light did come on, but that should reset). Plugged the hose in and it came back.

So in my case it was not a valve, lifter, or injector. With that noise gone, I could hear the injectors and they are relatively quiet compared to the noise from before.

So my question is - what is the cause, does it matter (can it cause other problems), and since the truck runs great, should I mess with it?
Thanks

Dave
