I have a 1999 5.4 f150 4x4 loud knocking started on passanger side also guages all pinned and bounced around truck runs rough and stalls what could it be

it sounds like a critical internal failure is eminent . if the oil pressure is ok,it could be a bent or broken valve as the exhaust leak can let the valves cool to fast and warp. however it sounds more critical than that. do a compression test on that side and see if the #'s are consistent.

Rod knock upon start

Not sure on model but to me sounds like its a dodgey valve lifter when the seals start to go they cannot hold the oil and when there under pressure they basically empty them selves hence when you turn the engine off and restart you get a rattle sound untill the valve fills again as long as the cars running ok leave it untill you have to replace them unless there easy to do sone are sone are a pain

I have a engine knock on a cold start. Knock goes away after engine gets warm

That is an indication of worn internal engine parts, it quiets down when warm because the metals expand tightening up the fit between parts. If it is a true knock then the parts that are most likely worn and causing it are main/rod bearings, or piston bores/rings.

MY 2000 Montero Sport has a loud knocking when i Start it UP ESPECIALLY WHEN ITS COLD IT GOES AWAY AFTER IT WARMS UP

Sounds like a hydralic lifter issue. These lifters operate the cylinder valves and run off oil pressure. When the engine is cold and the oil is thick worn lifters tend to rattle. When the engine warms up, everything expands and the lifters stop rattling. There is no easy cure for this except replacing the lifters. Sorry....

Car started noise like nock ing that was from Clutch in AC copmressor

It could be the compressor is going out, or the clutch itself is worn out. If the AC still gets cold, then it is the clutch.
