Question Ticking at low idle

Was just wondering what would cause my 2002 F150 4.2 v6 to tick while at an idle in gear. When you put it back in park the engine doesn't tick anymore. RPM is at about 600 when in gear and 800 out of gear. Only has 18,000 miles. Engine runs and performs great, just has this annoying tick while sitting at a stop light or siting still anywhere with it in gear.
Anyone know how to get rid of it. Change oil every 4000 miles. Use motorcraft 5w20 as recommended.

Is it a metalic type of ticking? umm kinda likea tin can, if so it is acutally your cats. if not it may alsao be your tranny, but my truck has a slight ticking only noticable at idle also, in gear or neutral never paid it much mind.

They all have that ticking noise. This issue has been addressed in prior threads. I had the same ticking noise under the exact same circumstances as you. I switched to 5w30 oil and that reduced/muffled the noise to a great degree. I don't even notice it anymore. We've also had extensive conversations about Fords idea of running a 20 weight oil in a truck engine and the "majority" of people disagree with Ford and run either 5w30 or 10w30, including most Ford mechanics. I'd consider a switch to 30 weight. But, I don't want to open THAT can of worms again.

The ticking is normal. Annoying, but normal.

Thanks guys for the info. It really sounds like a lifter type tick. Although there is no diferance that I can see in oil presure, it had me alittle puzzled. I've had fords all my life 3.0 and 3.8 v6's and neither has done this in passed.
I do agree greatly about the oil thing though. I believe I will switch oil weights and see what happens. Thanks again.

16.3 at 83?? You must have a great start, then slow down at the end. 16.3 should yeild at least 84 mph. Your probably shifting or redlining right before you cross the finish line.

That's great.

Ok, we've hijacked this thread so, back to the ticking problem.

Perk,

Let us know if the sound subsides after you switch oils.

I don't think that the ticking noise is normal. My 2002, 4.6 has a ticking noise during start up and at times during idle and running in gear. It is not a constant ticking noise. It is an intermittent ticking noise. I seem to think that the oil is not reaching the valves which may cause premature wear around the tappets(?). Any way somewhere along the threads someone mentioned that there is a oil pressure valve, or oil pressure relief valve(?) that is not functioning properly and that replacing it, with the upgraded valve, would resolve the ticking noise. How can I buy this upgraded valve,(if it exists), and that noone seems to know what I am referring to when I describe to them what it is? What is the correct name? Where do I buy this valve when the dealership parts warehouses in Phoenix, AZ don't carry it?

man, this thread is 2 years old!!!!!

I've had a ticking noise since day one of buying my truck. I switched to thicker oil 5/30 and that fixed the problem. the 5/20 they recommend was too thin.

the engine on my Yamaha 2005 makes a bunch of weird noises too. alot of it is normal though.

that 4.6 should last for 300K miles, regardless of where the oil is going. That's a good motor.

Tom
