Realize this is another size engine and vehicle, but sometimes a little extra info can help.



Clicking noise when truck fires up!
My Explorer makes a clickin' noise when you first crank it up. It quiets down once its been driven for 10 minutes or so. I had this older gentleman to listen to it from Advanced Auto Parts and I can't remember what he told me. However, he did conclude that I shouldn't have to worry about it because it's nothing that will affect the engine's performance. That was 3 years ago and I'm still wondering why is my vehicle making the noise. Oh yeah, it's a 4.0 V6 SOHC.




Sounds like lifter tap from poor oiling. Try running some Marvel Mystery Oil thru it for about 1000 miles just before an oil change, then go back to normal oil.

Clicking noise when truck fires up!
Thanks for the input. Now with this Marvel Mystery Oil, do I need to blend it with the oil that's already in the engine? Or do I need to change the oil and put the Marvel M. Oil in the engine?

Also, I'm not sure if any GA local auto stores will carry this brand. Is there another brand I can try just in case I do not find the Marvel M. Oil?

Thanks for your help!

Marvel is available in just about any parts store. You can also use Automatic transmission fluid but you don't want to run it in the oil for more that about 30 minutes. It will also clean the oil pump and engine internals. Drain about a quart of oil from your motor prior to doing an oil change. Add a quart of transmission fluid. Run the motor for about 20-30 minutes. Drain all of the oil, change the filter, and refill with your favorite motor oil. This should relieve you of a sticking lifter. If the noise continues after cleaning out the motor, you might want to consider replacing the lifter. Contrary to what you were told, it isn't good for them to be rattling against your push rod, rocker arm, and valve. While yours may be mild, it still isn't right.

Woohoo!!
Dave, you are the man!!! That's my problem exactly, and theres the fix!!! WOOHOO My next question is, I am a decent mechanic, that can replace most things, I just have to be told what to replace. Knowing what must be replaced, is this a hard piece of equipment for the 'casual' home mechanic to repair?

Thanks in advance!!!
Ben

Its not a job for the do it your selfer, unless you are way beeter than average, with a garage and lots of tools. The Ford dealer who just did mine had to pull the motor from the tranny and at least hoist it out of the engine compartment to do it.... I wouldnt even consider trying, and why would you if its covered up to 100,000 miles?

Pull the engine???
I didn't think they would pull the engine... The TSB shown by Dave shows something about 1.6 Hrs. I was thinking that's the repair time, but maybe I'm wrong. Also, I didn't realize that it was covered for 100000 miles. I'm calling my dealer RIGHT NOW!!!

Thx!!!!

The 1.6 hour repair is if the noise just happens when you first start the engine and then it goes away right away. The bigger kit is for if the noise is there after driving a while and at mainly higher rpm.
If I didnt have a good selection of tools and knowhow I wouldn't recommend trying either of them. The small kit involves removing the intake manifold and installing a different tensioner. It's not a real hard job but's certainly more involved than some jobs.
The big kit where the timing chain guides and tensioner etc get replaced is one that I for sure wouldn't do in my driveway unless I was really desperate and had lots of time and tools.
Check with your dealer about warranty on it.
