I would not use anti-sieze on the threads IMO
Last time i used it and 15,000 miles later 3 plugs were a little loose so i didn't use it this time.I would rather have them sieze a little then a plug blowout

 

I run NGK V-Power plugs should I change those out you think? I have a 1997 F-150 with a 4.6L I have recently rebuilt it and am having some troubles 99% sure its with the timing I messed up a little when putting it back together its out about 8 degrees. I have a post up already about it called "any thoughts" but anyway, should I cnahge out my NGK plugs for Motocraft ones?

 

No , your alright with those

 

awesome thanks man

 

Ok guys this is the moment of truth I have received the New COP's in the mail, have new SP 479's, and going to install this afternoon. Will up date to let you know how it comes out. Fingers crossed.

 

Man.. he's been out there for an hour..

And an above poster asked about plug brand.. I know peeps all have opinions and mine is Motorcraft all the way. Besides my '07 SuperCrew I have a 94 Stang five litre and have always run MC plugs, sensors, cap and rotor, and Motorsport wires and would never use anything else... Even after I redid the motor at 163k, (you could still see the machine marks on the cylinder walls ) I replaced every sensor and the tune-up stuff with ford parts.

 

I changed the COP's and the plugs, got no change in the way it's running or the loud knocking coming from under the throttle body area???

Got any new suggestions???

 

Maybe I need to describe my problem with more clarity.

I changed the COP's and Plugs, still missing, and the knocking is still there.

The knocking comes in on acceleration at about 1500 rpm and goes away at 2500, then on deceleration comes in at 2500 and goes away at 1500. At idle there is a decernable ticking not Exhaust but like a compression "tick", which sounds more like thht, thht, thht, coming from inside the engine.

 

Your knock sensor is right below the Throttle Body and manifold

 

OK will look for that this afternoon, thanks for getting back to me hope I can figure this thing out.

 

Hey guys checked the Knock Sensor, checked out fine, went to the IAC, looked bad and checked out bad.

Replaced IAC, started truck, knocking persists, looking at EGR, MOTOR MADE THESE SOUNDS bang BANG BANG AND LOCKED UP!!! I figure a wrist pin or a dropped valve.

In any event I owe more than the truck is worth. HMMMM???

What do I do now?

Going to sleep onit!!!

Thanks for all your help, will get back to you later, right now I have a date with Jack Daniels.

 

That sucks

Well if ya owe more than its worth you will prob have to fix it.A rebuild,new or junk yard motor....

They normally get over 200,000 miles with very few probs!!!!!

 

Yeah - He only has 81,000 on the clock !!! Wow!!

Well something went south

Are you the original owner ?

221,000 thousand on my 5.4L and it doesn't skip a beat..


That's some bad luck -

 

Yup almost the same miles as me (85,000)and i am not nice to mine .Mine runs better than when i bought it with 45,000!!!!

Fordman the truck looks in really nice shape,its worth putting a motor in IMO!!!!!

 

well damn... my trucks ticking too..i was told all trucks get a tick sooner or later...but its so annoying i want to fix it......but after reading this idk if i want to mess with it lol
