What are you asking?If it is a lifter, valve cover will have to be removed to check it.It could be that rockers need adjusting but if lifter is bad you will have to remove the intake manifold and replace lifter.

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

WHEN STARTING KIA 2008 SPORTAGE A NOISE SOUNDING LIKE LOOSE BOLTS OR NUTS FALLING AROUND.LIKE SOMETHING KNOCKING AGAINST A COVER OR SO.GOES AWAY AFTERWARDS THEN COMES BACK WHEN IDLING ..


hydraulic lifters fitted to that engine
shimmed adjustments

that rattle on start up will happen
takes a few seconds to fill with oil
if lifters are worn
motor run low on oil or not serviced regularly

faulty ones can be replaced

other rattles can be idler pulleys

My 2ltr V6 Vitara has a rattle. Top End noise, it rattles like noisy tappets on start up and gets less as the engine warms up (around five minutes) then it almost stops. So far I have pulled the rocker...


this is not SOLIDS engine, there is no LASH setting, !
the engine has a chain, and a set of hydraulic bucket valve lifters.
the chain can be bad or any lifter, can be dirty and collalpesd.
when the engine is dead and no oil pressure the lifters are normally collapsed, when you start the engine. oil pressure does 2 things
all lifters pump up, and clearance goes to zero. (no noise)
then the cam tensionor, pumps up (they fail) and chain noise ends.
some noise is ok , cold start, but most end after a minute or 2.
started.

ever read the manual? its here.
use a stethoscope to find out 1 thing , which is it the chain or lifters making that noise.
ive even runs engine with the valve covers off (messy , use a blanket to catch oil flying) to find the true cause.......

read the 2.5L here. its close. (mech. parts)
read the Alldata virtual FSM.

Hello, I have a 2001 chevy tracker with a 2.0 engine. It has a ticking noise after it warms up. during up shift at RPM's about 3000 it rattles like lifters, but go away after the shift. Some times


when oil is cold it is thicker and stays [on]coats metal as oil warms up it thins out and flows better[makes it thinner will hear ticking] sounds like a bad lifter or even camshaft lobe problem ,could also have a problem with a loose or out of adjustment rocker arm

Jeep 360 rattle sound at idle in park


it could be a wrist pin, and im not sure if those amc's had hydraulic lifters but sometimes with old lifters when the oil pressure is lower at an idle the lifters arnt filling up all the way so they develope a little valve lash, and when the rpms are raised the oil pressure raises and fills the lifters. you could try chasing the noise down with an automotive stethoscope.

Hi, i have a toyota fielder 1.8cc with a some problem which has now come up. when i switch on esp in the morning after staying overnight, it produces some really annoying sound from the engine. when the...


If it is a 'squealing' noise it's probably the alternator/power steering drive belt. Before you turn on the engine in the morning, lightlt smear or spray some oil on the inside of the drive belt to lubricate it. If the squealing stops/disappears, then that's the fault ..

That squealing noise can be caused by an incorrectly tensioned belt, or a worn belt. Replacement is the only option.

The other frightening sounds can best be described as 'rattles' or 'tapping'. When a car stands overnight all the oil drains back into the sump (oil/pan).

There are two things (usually) that can be cause the rattle/tap:
1. Because the oil hasn't been pumped around the system, at start up worn big end bearings can rattle and tap on the crankshaft until the oil 'fills the gaps'. The tapping/rattling goes away as the engine warms and oil is pumped around the lubricating system.

A 'bottom end tapping' is a symptom of worn big ends (they are bearings at the bottom of the piston and fit around the crankshaft).

2. A rattle/tapping from the top of the engine can either be a worn camshaft or 'lazy tappets'. Again, when the engine warms and oil gets to the camshaft and tappets (also called 'hydraulic lifters) the noise will disappear.

If your car has this rattling/tapping noise - identify whether it is coming from just under the rocker box (ie the camshaft/tappets..) or the bottom end of the engine (big end bearings).

If the noise is coming from the top of the engine, try an oil change with a can of thick 'additive' included. A lazy tappet (lifter) isn't too much to worry about. A worn camshaft will affect the performance of the engine, though continue to do its job. An oil change with an additive included may help in quitening things down.

A bottom end tap/rattle (or 'knock') - the sooner that is sorted out the better.

Rattling noise when cold start. noise dissapear when engine warm up .2000 Ford taurus SE


You problem is most likely just lifter noise. This is common with a lot of Ford engines with self adjusting lifters. Although lifter noise is bothersome it doesn't pose a serious problem. Unless your engine starts to miss or your gas mileage drops way off lifter noise is just an annoying problem.
I would recommend that you add some Sea Foam Engine Treatment($6-$8) to your oil. This is not an oil treatment it's more of an engine cleaner. If this works you'll need to add it every 2nd or 3rd oil change.
If this doesn't take care of the problem then depending on your engine you may have adjustable rockers that would allow you to remedy the problem. If not, your options are limited to living with it or replacing the lifters and possibly other valve train parts.
