my bearings rattle when i change my oil and i fill the new filter with oil and i only use moble 1 synthetic, i read this is norm, am i the only 1 with this prob

 

do you mean they rattle on start up right after you change your oil?

 

What type of oil filter are you using? Make sure to choose one that has a proper antidrain back valve.

 

i use motorcraft filter it is the wright filter. and yes it only rattles at start up like 2 or 3 seconds

 

Do a search and you should find the answer I found here 3 years ago with a better description than I can offer here. Since the oil filter mounts at an angle tou can't prefill it any more than about half full. So fill it as full as you can without spilling when you tip it to screw it on. Then push the gas pedal all the way to the floor and keep it fully depressed while you turn the key and let it crank for 10 full seconds. This pumps the oil filter full without starting the engine so you are not running the engine at high RPM with less than full oil pressure. Turn key off, release gas pedal and turn key to start as you normally do. No more awful sounding clatter. Why this works was explained in that thread three years ago and maybe somebody else can explain it. Anyway why can't all oil filters be mounted vertically so they can be fully prefilled?

 

thanks for the info,i will try that and let u know the outcome.

 

Basically your sending a 5volt signal from the tps which is putting the car in clear flood mode which cuts off injector pulse, which is why the truck wornt start. Good idea to circulate oil.

 

It works. I was really nervous the first time. It must work on all recent Fords. It works on my 3.0 Escape, my 4.6 Lincoln and my 5.4 F-150.

 

Should work like that on all fuel injection. Car companies introduced clear flood mode into the pcm's when they were switching from Carburated cars. They did this so if people still stepped on the gas the car wouldnt rev when being started.

 

A numnobb like me has actually learned a lot from others on this site in the past 3+ years. Thanks for explaining why it works.

 

The true reason the manufacturers did this is because when carburetors were the norm, the fastest way to start a flooded engine was to push the pedal to the floor. When fuel injection took over, they built that into the system to make it an easier transition for the public. Pushing the pedal to the floor on a fuel injected engine shuts down the fuel pump to allow the engine to crank and clear out the excess fuel from the cylinders.

 

This site is just too great in that a few other dudes who really know what they are talking about will chip in with real detailed answers fo somebody looking for them. Again thanks to youz guys! I have to confess that I just spent the past 5 hours detailing the F150 for da winter as we say here in Wisconsin and dat der job requires many brewskies to complete and I am guilty. I am toasted so Good nite.

 

Who/what is your source or did you just take a guess at the expense of everyone else thinking you are right?

The fuel pump doesn't shut down. Instead spark advance is increased based on pedal position over temp.

 

Do you even understand what I was saying, or did you decide to criticize my post without fully reading and comprehending it?

BTW what are you trying to say?

 

Sorry Tbird, but "the true reason" was already explained by :

The injectors are affected, NOT the fuel pump. This is just basic EFI standards, not brand specific.
