After looking over the warranty, it says that any internal engine parts that is oil lubricated is covered by the 5yr/60,000 warranty. I assume that'd cover the cam phasers since they're oil fed?

4.6l 3v is ticking like a sewing machine when warn and we're at 35,600 miles, might not be able to get it to the dealer before the 36k is up.

Mine has 9k miles on it and it ticks like a sewing machine. You're may sound different, but many people have discussed this. For most of us it's just the injectors.

i used to have a 1990 ford ranger with the 4.0 L motor and it ticked for over 100,000 miles until the intake manifold gasket went out and all the water leaked out and i drove it to far and cracked the block. I think mine only ticked when cold and stopped when it was warm though. been a few years, i forget.

ummduh

This isn't injector tick. It doesn't come on until the engine is up to temp, and then only at low engine speeds. Idle to 2500RPMish.

From searching on here I'm pretty sure it's the cam phasers.

No clues on if it is covered beyond the b-t-b warranty?

Got 8500 miles on my 4.6 V3. It has ticked between 800 and 1500 RPM since I got it.
Never have taken it in...seems that no one really knows what it is or if it gets fixed by the dealer.

May just take it in so there is a record of my issue. Anyone ever have it fixed by a dealer and the ticking goes away...?

iamsuperbleeder

mine tick like mad on my 4.6 3v, and mine has less than 6k on it

only does it if I get on the gas a little harder than normal when at a low RPM


as long as they don't get horribly worse, I'm going to deal with it. if they last until the warranty is up, then I plan on installing some FRPP Hot Rod Cams, and I'll be installing the cam phasor lock-outs at the same time

Cam phaser issues tend to sound more like a knock then a tick. Just had min replaced on bank 1 at 12,4XX miles last week.

ummduh

The 4.0l has a known upper valvetrain problem, they don't get enough oil and the pushrods wear into the rocker arms. Pretty common and they'll last a long time like that, mine did.

However we just bought this f150 recently and the sewing machine noise is pretty annoying.

Sounds like you may be talking about a knocky rattle that only happens at low rpms if you give it gas. Mine has done this since new. To me it sounds like knocking from bad gas. The only way I've been able to prevent this is to use 93 octane which is ridiculous. It completely goes away with 93 and comes back with anything less. The truck is designed for 89 octane. I've asked the dealer several times, but they just say that it's normal, or tell me to try different brands of gasoline, yadda, yadda.

Dealers dont know dick but anyways I have always run Shell or BP gas in my 05 FX4 and always use the best. 93 octane is the way to go. You only spend a dollar extra every ten gallons. People make it seem like thats ridiculous. Just pony up the extra cash and put the good **** in. You get out of it what you put into it
