Lifter noise in 5.4 ( my 1st post here, be gentle)

Howdy everybody! This is my 1st post so forgive me if this is in the wrong spot...

I have a 97 Expedition w/ a 5.4, 2WD, 125K and the lifters are rattling in the morning when I start it. It goes away in 15-20 seconds. The oil pressure reads good. I am using Exxon 5W30. The truck runs great but this is driving me nuts!!

Any suggestions. I ran some Marvel Mystery Oil through and it helped, but the noise is still there.

Thanks,
JC

Are you using 5W20 motor oil? Those engines have close tolerances.

The exact same thing was going on in my mustang. I just replaced the lifters..it's not back together yet, still wainting for the water pump but I'll let you know if it fixes it..

I have a 99 i thought it was thr lifters also but i found out under the intake manifold the is a plastic casing that wraps around and it was loose and it was making the sound u might want to look in front where your intake manifold goes on and see if u have that plastic piece

I am also experiencing the same problem....Is the noise actually the lifters?

Could someone point me to a thread that deals with this?

Tried searching "rattles" but too much reading...LOL
