How to replase the timimg chain of a Ford F150 Engine 5.4

USA car> RTM its in the manual
PCM dictates firing order this is a fact and any cam chains.
no job told at all, why? doing this.,
pulled the coil pack and not do HV wire 1by1.? oops. thart?
V8 , has 8 COPS THEN, and harness wires and CPM dictate order
so you doing ACTS with the CAM?not told the job or act.
#1 is ,the bank that is most forward bank of al V engines.
so we all know just at a glance where is #1
now banks
order
1 - 3 - 7 - 2 - 6 - 5 - 4 - 8
right front is #1 (drivers seat perspective)
even odd banks.R 1234, L=5678
2nd google finds this.

There is no real timing chain adjustment. If the timing chain is loose, it is because it has stretched beyond the ability of the tensioner to compensate. You'll need to replace the timing chain. (Yes, it can be done without removing the engine, but it's a tight space!)

Signal Generator Problem

how many miles on the vehicle? does the noise quieten down when the engine RPMs come up? timing chain is very likely if you have over 150,000 miles. lifter noise is a more common problem. the lifters will tend to quieten down as the RPMs come up due to more oil pressure.

If it looks brittle I would replace it, with plastic parts if in doubt replace it. if it is a cheap part you could save a lot of time and trouble by replacing it now wile it is apart.

Both V8's and the V6 engine offered in those trucks have a timing chain and not a belt. They do not require service for the life of the engine.

they should point to each other

You have to remove the radiator,it's best anyway as the radiator can be easily damaged when working on the front of the motor.

I would check the oil pressure of the engine. The reason is the timing chain tensioners are run with oil pressrue. I think your timing chain tensioners are leaking down when engine is getting to operating tempature . The oil is thinning down as warms up , as it should to lubercate . I would check compression and do a cylinder leak down test on all the cylinders. Then if the compression is good and the cylinder leak down is good. I would change all the timing components, ( chain, timing gears, timing chain tensioners )

Good Luck , I hope this helps.

took it to a ford dealership to be repaired
