ok i have a 2002 5.4 2v with 115000miles or 195k and i a have tick or knock coming from the engine, hot or cold doesnt matter. doesnt matter what type of oil i use even with lucas additive it doesnt change sound.i can only hear it from idle to about 1700rpm but its not as loud under load. the truck uses a little bit of oil nothing major and power doesnt seem to be to bad ive never driven another truck like mine so i cant say if its normal or not. thanks for any input

 

Well, hopefully, you don't actually need this any longer.

If it is a ticking noise that is rythmic and sounds like it is just about in time to your ignition (timing) system. Then it is one of your spark plugs "backing" out.

My 02 surper crew, blew a plug out as I umped on it getting on the interstate. stripped the threads out of the head.

This is a known issue with, at least, the 02 models according to the Ford dealership, and was fixed with inserts and different (longer thread area) plugs.

 

yeah the ticking follows the ignition as far as i can tell. is there anyway i can check to see if this is the case without wrecking the threads

 

i cant hear the tick over 1700rpm is that normal

 

I could only hear it at lights/stop signs before mine blew. Most likely because that was the only time something was beside me to bounce the sound back without any wind noise.

Unfortunately I didn't know about the plug issue with the 02 (and others) F150, but there are multiple articles in this forum addressing the plug issue. I saw one the other day that listed the "improved" part numbers for the recommended plugs. Plus some tips on warming the engine before trying to remove the plugs. etc..

Hope all this helps and is actually your issue. If not, I hope you find it.

 

I have an 02 doing the same thing. Have you looked under the hood to try and figure out where yours is coming from? Mine is on the passenger side up high on the motor, checked the plugs and exhaust manifold and all are tight. I understand that the plugs and manifold bolts are known culprits on these so check those first. The plugs are hard to get to but with a little time and some tools it is not too bad.
Check those two areas first, Good luck!
