SOURCE: Noise under intake manifold

best thing to do is to take the intake and valve covers off, its possible you may have inadvertently sucked something up and it's in you intake. That is the best solution.

No telling what it is until you take things apart and take a look. It shouldn't be too hard, make sure you get new gaskets, gaskets are cheap anyways.

SOURCE: lifters making noise how do you adjust them?

The engine/oil pump may be worn enough that the oil pressure is too low at idle. Suggest getting the system pressure read at your favorite service shop and get an estimate of required repairs. Have you been getting regular oil changes?

Hello Dave.

Often the result of low oil pressure is noisy lifters.
This is because they are the last of internal engine components to get oil pressure.

I don't want to bore you with details, but I have to begin somewhere here:)
In most lubrication systems in automotive oil is picked up through a screen at the bottom of a tube at the bottom of the oil pan. The oil pump picks up the oil, pumps it into passages to lubricate the engine.

Ok, so in order to develop pressure, there has to be a restriction to create it.
When an engine is new, the clearances in the oil pump, engine bearings and valve lifters is close tolerance where little oil is allowed to escape. But it does flow enough to keep a film of oil between the moving parts. Theoretically, no metal parts ever touch due to this film of oil.
As the engine wears from normal use or sometimes neglect, these tolerances widen and the oil runs out faster so the pressure drops.
If it drops severely enough, some parts will not get the oil they need.
Oil pumps also have a valve on them to regulate pressure. Perhaps this regulator is a problem.
You will need to find out what it is on your engine that is allowing the oil pressure to drop.
This may necessitate removal of the oil pan to inspect crankshaft bearings.
There are a few mechanical hints for you.
If you need further advise concerning this, ask me here.
Thank you for using FixYa.

My rocam 1.6 how do i know if its my hydrallic lifters making a noise


If the noise goes away when the idle speed increases its not the lifters, check the oil pressure is ok at idle and increases with engine speed, check the oil is not to thin or wants changing, the oil pump relief valve may be stuck or the spring spring broken.

Audi a4 1998 tapping noise only when idles under valve cover


Sounds like a bad valve lifter or a valve out of adjustment. It's probably a bad hydraulic valve lifter. In idle, when the oil pressure is lowest, it is not filling with oil. When the motor revs up, oil pressure rises and fills the faulty lifter.
If you do have mechanical lifters, the valve is probably out of adjustment. If you do car work, pull the valve cover and see if it's adjustable. Of course, you'll need the specs from VW/Audi.
Otherwise, it's probably a shop job.
Sorry.

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.

Will intake gasket leak make the lifters tic when first starting


I dont think and intake gasket will cause lifter noise. It may cause a rough idle and or a miss at idle on cold start up . as the engine warms up the miss or rough idle will decrease . As for the lifter noise this could be cause by the lifter bleeding down or poor oil presure . On your model of engine there is no adjustment on the rocker arms for lifter noise . They are a 0 lash type .

Does my 1998 Toyota Camry have a lifter problem there s a clicking noise when engine is acclerated? What can be done to fix this problem?


Might be a lot of thing, verify first at wich rpm the noise occures, in which situation. A clicking noise at idle and faster rpm could be the lifters, crank or even injectors (they tend to get noisy when they get dirty, saved one of my friend's tercel with a good presure injector cleaner). Try to duplicate de noise and see if it comes from the top of engine (cams, lifters) or the buttom (crank). If the noise ONLY happens on accelerations it might be a timing problem (pinking, it sound exactly like you were breaking glass). If so get the timing fixed ASAP, pinking can melt a hole in a piston in no time.

1997 Mazda Protege: Engine has clicking noise when idling.


Check to see if the valve lifters are not making the noise. Turn on the engine and rev it up to about 1500 rpms and see if the clicking is coming from the valve cover area.

Clicking noise


Probably not lose - more likely sticking.

The 'old' way of curing this was to dump a quart of kerosene into the oil, let it idle for a half-hour, drain oil, change filter replace oil.

You might try using one of several products at parts stores that claim to free 'sticky' lifters.

The clicking, if coming from the lifters indicates that the lifter no longer travels freely and the near-zero clearance isn't any more.
