^its definitely a start...

 

hopefully a start that wont end too bad... if this truck winds up being a piece of junk im getting rid of it and buying something else bec i cant afford a money pit, that's why i bought a "new truck".

 

this is kind of off topic but i started the thread so i guess im allowed to ask hahaive read about what they do but why do they spin like this within themselves? that metal piece with the spring isn't there from the factory of course but why do they move like that?

 

they spin within themselves to be able to advance and retard timing... basically to maximize efficiency. VCT = Variable Cam Timing and the phasers are bolted to the end of the cam

 

oh ok i get it now... wish i didnt but i get it. i feel like ford couldve came up with something a little better than that..

 

This is a helpful video that [MENTION=37089]Cutless009[/MENTION] showed me that explains the workings of the phasers. It's not on our engine but it's on a Ford so it's the same concept.

 

A lot of engines have variable valve timing now...its actually good as long as oil vct solenoids and filter are all correct and in working condition.

 

tareed94 thanks for that video, that really did help me out with nderstanding how all of this stuff works. i could work on my old expedition with my eyes closed but this is all new to me so im trying to learn how it all works together and how to keep everything nice and in working order.

 

You're welcome. It really helped me visualize how that works with everything. I grew up working on an 01 expedition which is what my mom drives. It's in great condition with no major issues other than the windshield leaking a few times, and the roof in the back leaking requiring it to be rewelded. Other than that it's caused us no major issues. Paint is starting to oxidize on the hood though. It's a tough vehicle.

 

Yea my expy is a 97 and it's got 243xxx miles on the original tranny and motor and still runs good is just nickel and dimeing me to death.
