Phaser lock outs installed!

What a nightmare project. Over 8 hours in it and it was sludge and varnish city. Previous owners neglected it obviously. Timing chains where surprisingly tight for 150k and the guides looked good still from what I could see. My heart dropped though when I fired it back up, took a while for the lifters to pump back up even after cranking it a couple times. Ratchet straps got the ac lines over enough to get the valve cover off. Get my new tune this week and back on the road.

editing recap,
so after the tune and making sure my rear o2 sensors where left on it passes smog with flying colors. runs great and no complaints with it after the lock outs. 500 miles on it and its ready for some long haul camping trips this summer. would do it again in a heart beat well worth the money and did it all for under $450 including the tune. no need to fear the smog station and it did it without shutting off a bunch of stuff.

It's not letting me post the pic for some reason but they where pretty revealing. Only good thing I really saw was no scoring on the cam lobes. Now i can't wait to play with the tuner......

cant really drive it until i re tune it. with the tune and the phasers shut off it should honestly be the same. you will lose some top end but its been tuned and the fuel and spark optimization will balance it out.

cleaning up the garage today and found a remnant piece of black pvc pipe so i essentially i pulled off a "gotts mod"
tuner should be here tomorrow so i can wrap this up by the weekend.


due to patmans comment and my curiosity i took the truck out and beat on it pre tune with the vct noids unplugged. ran just like it always had pulls the same up to 4k (around town) while im sure it is probably down a couple hp its nothing i can notice. squeals the 33s of the start fwiw. apparently i didnt get all the oil that leaked from the passenger valve cover, can smell it burning but dont see anything leaking.

final post to finish it up, after the 5star tune its a night and day difference. the lock outs gained low end torque even with out the tune, after driving around with the tune its sad how bad this thing came stock. lots more torque and better power everywhere in the band. pulls like a truck and the trans mods just added to it. have to give the truck a little more credit now.

Im in the middle of tearing mine apart. My pass. side upper guide was shattered and I didnt even know it besides a little chain slapping at cold start up. Im going with a Mellings 360 oil pump and leaving the new phasers unlocked. We'll see...

Sorry, but just for the sake of good, sound, accurate, information for others, I would be most interested to hear a technical (logical) explanation just how lock outs produce this extra low end torque OVER properly functioning phasers - which move phasers/cams to exactly the same (fully advanced) position when max power is demanded.


Please?

I know very little about the VCT but I do know that I test drove a used 05 SWB F150 5.4L 4x4 in 2006 and it didn't have the power of my 2000 F150Scab4x4 5.4L. Then I test drove a new 2006 F150 Scab 4x4 5.4L and it was the same. My 2000 2V 5.4L would blow the doors off the 3V trucks, at least in a 0 to 60 situation. So, I can only surmise that the VCT was about emissions and not hp.

No, it's more to do with the weight difference in the trucks.

About 500lbs difference I think. 40 hp difference I think. Should be about equal in a 0 to 60mph drag race I would think but Nope. Kind of like my 95 Mark VIII Lincoln with the variable intake. It was a dog below 3k rpms and then it felt like a turbo kicked in. Still think it's all about emissions and fuel economy.

Please?
they are retarded at most situations unless max power is demanded as you say. No one has there foot to the floor every time they drive so yes by always having them not retarded you will gain more torque for more driving conditions. It was always there but it was not available. this has been proven by people with hp tuners, there is always some * of retard commanded.

I know, I have monitored variable cam operation extensively with Torque Pro. https://www.f150forum.com/f4/final-r...4/#post5133357


I believe everything you said is basically true, but still doesn't answer the question - and raises others.


What happens to that extra torque in those other driving conditions when it is not demanded or needed by the driver? It is true, most (light load) driving conditions employ some varying degree of retard. BUT Properly functioning phasers even apply some increasing degrees of retard under high load conditions as RPMs begin to rise above about 4,000 rpm. (to add high end torque).


But: How does locking phasers at full advance produce more torque OVER properly functioning phasers? - which will position cams at full advance at the proper time for delivery of best torque?
