That's not a good thing to change the oil but not the filter. Filters dont filter ultra-fines as it is, only large particles and it's not too expensive to slap a new filter on there at oil change. I would not buy the truck just because if the PO would cut corners like that then what else did he do half-assed? Besides that truck will get horrible fuel mileage.

 

i agree. i would run away from that truck as fast as i could.
unless the body was in mint condition and the selling price was low enough to be able to replace the engine with new from ford and still be worth it.

 

Two questions:
a) Where is this "purge valve" located?
b) What does it do?

I have a 2012...does that year have one? Sorry - three questions.

 

The purge valve can be located in various placed on different vehicle; I think it's under the hood on our trucks.
It is part of the emissions system relating to gas vapors.
Yes - all gas vehicles have them for a long time now.

 

Yes, that is why I am still ina debate. The body is in great condition. The price is 15k USD. There is work to be done on the 4x4 (IWE fail) and some on the undercarriage (around 2k extra which I believe is tolerable on a 9 year old truck). No quotes on the engine swap yet, but I think at least 7000 minimum.
Due to some sings I suspect he did excessive idling too which again might not be a good thing.

 

1. Center of the driver's side of the intake manifold, has two bolts holding it in, a wire harness and a tube connected to it. Smallish, looks like it has Mickey Mouse ears.
2. It admits fuel vapor held in the charcoal canister into the intake to be burned.
3. Yes, they all have one.

 

The way he changed oil is very strange but it may not have killed the motor depending on the conditions it was run in. When I look at a vehicle with unknown or questionable maintenance I give the whole running gear a good once over and pay special attention to oil leaks. When it comes to the motor I take it for a good test drive without babying it so it gets good and warmed up, then with the help of someone you trust remove the oil filler cap, block the tires and have someone put it in gear lock the brakes and step on the gas, if any oil vapor come out of the cap (blow by) the motor has problems but if no vapor comes out the basic motor is sound. If the oil was comtaminated enough to damage the bearings everything else would also be affected, if it has any oil in the rear main area walk away because a bad rear main seal may also mean bad main bearings.

Buying a used vehicle is a crap shoot and I alway figure on some repairs, my last one was my 03 F150 with a 121K miles and I knew it had a manifold exhaust leak, bad idler belt pulley bearings, front brakes and rotors needed replaced and a few surface rust spots on the box but it had no oil leaks and the motor passed the blow by test. After I bought it I changed all the fluids, all the brakes replaced, pulley and belt changed, new shocks, the dreaded exhaust manifold leak fixed, rear U joint, rust repaired and a lot of small things taken care of and now I have a good looking trustworthy truck that I would take anywhere and it doesn't use oil.

Pull the oil fill cap and have a good look with a flashlight for sludge build up. Their should not be much more than a brownish film if it was maintained well.

 

The purge valve is the plastic part held in place with the two " screws" , this is the position for the 6.2 the connection clip is something you are going to need to fineness in order too unlock and pull release.

 

Clear all fuel code error after installation , this was one of the main reasons i had the ruining rich code pop up regularly . Thankfully this very form assisted me with this very ford "fault" / should of never changed from canister.

 

 

amazing! I knowou have posted it quite awhile ago but would you mind posting what maintenance items you have replaced during these miles?

 

SHOW OFF!!!

 

lately the only thing I have done to it is front-end work like ball joints and tie rod ends wheel bearings things like that. I remember putting a fuel pump several months ago as well. that stopped my long crank problems I was having.
I'm still using the original transmission and rear end. And I also put some new shock absorbers on the front

 

Ed, any idea how many hours your first engine had on it?
