Okay so I found separated Lifters, two of them.
The little cup that holds the check ball and spring was on the wrong side of the “shuttle” I think these parts just worn out from me messing with them on the bench.
I needed to learn how to disassemble and clean lifters… well they were clean! But two of them separated
Live and learn
I feel good about this repair because I can see the problem.
All the old stuff went bye bye
16ea New motorcraft lifters
New melling pushrods and rocker arms, pedestals
Pushrods stock length, I confirmed the length of the new ones
I just primed the oil pump with fresh oil have to install valve covers and intakes then we will finally (I am confident) have a proper running 5.0 and we can tune
Old lifters 152k miles and bench cleaned, ran for 15 min , noisy, removed and found the issue
Parts table is back with parts on it again
Out with the old
Bad news, this little ball and spring are supposed to be retained in the bottom of the shuttle
So… off to the metal yard with the old valvetrain
In with the new
Now you guys there is so much wrong info out there in 5.0 land. These are pedestal
Mount rockers, there is no such thing as bring them to zero lash then torque down, how many turns it takes… that is not how you torque these that is not how you check pushrod length. That info is for the stud mount rocker arms
These pedestal mounts are simple. You tighten the bolt the pedestal is now bolted to the head… there is no adjustment
The only way to adjust things is to add shims or remove material from pedestal… and even then you really should be getting different pushrods
For me stock length pushrods stock rocker arms.
Simply torque the pedestals to 24 ft lbs and you are done. You don’t have to turn the engine over it does not have to be at tdc… none of that applies here
The 24 ft lbs is simply to keep you from over tightening and stripping heads/ bolts
Now when intake was removed some water went into crankcase
So old oil drained, new oil added and now the oil pump is primed with drill
Counterclockwise
Watch the oil pump up lifters and come out all pushrods
Camshaft synchronizer was removed from engine so can access oil pump drive shaft
I removed the sensor from the synchro body and marked the location of the flag so I can re install on same cam gear tooth
All new parts were soaked in oil before install
New ford lifters slightly different shape then the originals from 2000
I like to install lifters with the oil hole pointed towards valley, although it really does not matter
How many times do we have to see valvetrain re done in one truck? Hopefully this is it!!!
