Loose rocker, bent rocker, bent push rod, loose or bent rocker stud are a few things that come to mind. Take off the valve covers and with each cylinder at top dead center, check the play on each rocker assembly and inspect for any bent parts. Visually look down, and to the side for any mis-alignment.

1995 Isuzu rodeo v6 oil pressure low all times been like that for 13years 202000 miles top end rattles a little any ideas what to check first


have the oil pressure checked with a mechanical gauge
top end noise can be from worn rocker gear
if the rattle is under acceleration or load it could be detonation so run the fault codes

My Lincoln Continental 2000 Model oil light came on engine stopped after 25 feet. would not restart even though oil full. The car started the next day, but had a rattling sound at the top of the motor


Oil light is rather important it goes out if oil pressure is good comes on if oil pressure is low when it comes on damage is expected with continued operation like wearing of main bearings and pistons and cylinders can lead to a engine rebuild

Lifter noise


yes they do wear out and will not hold oil pressure. I would be checking the pivot points of the rockers and the face of the rockers where they hit on the valve end. I say this because if the hydraulic tappets were so bad you would have very low oil pressure at idle.

I have a ticking noise i was told it may be a loose rocker arm or a rod bearing... really hope its a rocker arm. but it get worse when the motor warms up, and only ticks in mid rpms when in high rpm the...


One thing you should get checked is the oil pressure.You could have an oil pump that is going out or getting weak.Also depending on how regular you are with your oil changes it is possible that you could have a sticky lifter.The oil pressure at idle should be 4 psi and 25-80 psi at 3k rpm.If it is less than 4 psi at idle do not do the 3k rpm.This is check with a warm engine.(normal operating temp).Hope this helps.Good luck.

My Navigator makes a rattling noise at startup and then it continues to make rattling noise while idling. What could be? Possible lifters, rocker arms, and pitons rods possibly?


if rattling sounds like you have a bad pulley bearings on pulley going out pop hood and look at belt with running see if it is moving correctly not going in a back and forth motion like warped llook at pulleys see if they are displaced

Loud ticking/knocking/rattling sound when I start/accelerate


hi is it miss-firing as it sounds like a knocking noise can be anything but if you can feel it on the accelerater pedal then the noise sounds like its on the inlet valve side which would transfere the noise up the throttle body where the accelerater is located it could be something as simple as a tappet come loose to a burned valve you need to have a look do a compression test and take the rocker cover off see if theres anything come loose yates210456
