Have your oil pump and oil sending unit checked....
the noise you are hearing is going to be from the engine not having enouph oil to either the top or the bottom of the engine.
If you do not have enouph oil getting to either part of the engine than you will loose compression and compression makes you move. i would start there

What could be the cause of a rattling noise but engine never shuts off. No Mil. Alerts or any stuttering. just loss of power and loud knocking noise the more you rev it?

I have had personal experience of a head gasket blow the dodgy mechanic who re-built my motor at the time did not clean the head bolts and so they were not tensioned properly (I digress). Anyhow it blew between two cylinders - man what a racket! I thought my engine was kaput. In short my answer is head gasket - could also be a burnt out valve but most likely something in your top end of the motor.

Clicking noise under hood - have repaced alternator belt and pulley

i dont want to alarm you but you really need to check into this. the only 98 explorers i have heard with clicks have led to timing chain slider failures which is not a good thing,it was cheaper to buy used motor than to repair. go have it checked out or while the motor is running put your hand on top of valve cover on the rear pass side and feel for clicks or small taps or knocks while reving motor slightly. and repeat on the driver side front of engine. and i sure hope this is not your clicking noise location.

Sounds like a small tapping in the motor but no loss of power, and shifting smooth still. What is that tap?

Could bad a lifter gone bad or dirty, start with the simple and add a bottle of to your engine oil. This free up and lifters that may have dirt in it, it the noise is still there. The most likely your going to have to have your rocker arms or lifters replaced.

Thank you for using fixya and good luck

Loud metal noise inside motor but still runslike snapped connecting rod or could be vales making the noise varies with engine rpm severe loss of power

this might be an injector fuel blocked and to be sure for the noise need to fiil into tank fuel 100 ml SAE 10 AFT oil and to check out the air flow meter for the loss of power

1998 ford expadition ticking noise ,sound like valve spring broke slightly rough idel loss of power. oil pressure good every thing seems fine.

have your engine valve tappets adjusted to its specified adjustment by a competent mechanic then if the noise is still there then you need to have the engine timing checked. if these doesnt solve the problem then you need to pulldown the cylinder head to inspect the camshaft condition...

Lifter tapping

The tappet noise usually will get louder and louder as it wears. A totally collapsed lifter will definitely be noticeable by loss of power to that cylinder, misfiring, and excessive noise. But then again your current lifter noise could be possibly maintained for years to come by regular and consistent oil changes.

more than lickey you need to have a new oil pump or oil sending unit installed. the tapping is due to not enouph oil to either the top of the engine or the bottom of the engine. if you do not have enouph oil pressure it will cause you to have low compresion and you need the compresion to move..... if you have some but not enouph compression than you will loose power trying to take off in fast paced traffic or up a hill and from a stop light....
