Sounds like it's time for some basic maintenance. Some of the emission controls require changing. More specifically, the PCV. Positive Crankcase Valve.

At 60,000, and 100,000 miles this are supposed to be changed, but conditions may require a change sooner.

Hello jhuezo....check the PCV (positive crankcase ventilation) valve. These should be replaced periodicly as routine service.
There are other possibilities...mainly involving gaskets and seals.. but it's usually best to start with the obvious. I assume you have the non-turbo engine, if not then thats another thing to consider.
Hope this will fixya up...thanks for stopping by with your question.

Bad oil pump ?


Turn your A/C off, the compressor can make noise if bearings are dry or system is low on compressor oil.
Remove your serpentine belt. Turn pulleys by hand to check for roughness. Bearings in those pulleys routinely go bad.
You may get computer warnings with the following test, but with serpentine belt removed, run engine for 2 or 3 minutes. Do this on a warm engine after serpentine belt is removed. The warm oil will not mask the problem like cold thick oil can. Noise generated means problem is internal.
If this is a stick shift transmission sometimes the clutch bearing can make noise and is a sign that bearing is bad.

2006 volvo s40 50,000 mi. noticed a noise under hood that sounded like a belt slipping. sounded more like it was coming from the back of the motor. With the car running,I took the oil dip stick out and the...


The oil filter housing also houses the pcv system. What causes the noise is that there is a check valve in the pcv system that is supposed to regulate the pressure in the crankcase. The valve gets stuck and causes vacuum to build in the crankcase, which in turn sucks air wherever it can causing the noise, which is also why when you pull the dipstick it stops. This can also cause a check engine light with codes for fuel trim. The oil filter housing will need to be replaced. Good news is that Volvo extended the warranty on these to 100K miles so it should be free of charge at the dealer. One thing to watch for is oil leaks after the replacement from the camshaft seals. If air can get past a seal, usually oil can too. If the seals leak too long it can contaminate the timing belt and cause it to break, which causes a lot of damage.

Whirring noise


HELLO, I HAD THE SAME PROBLEM. I WENT TO THE DEALER AND WHEN THE CAR WAS MAKING THAT WHIRLING SOUND, HE UNSCREWED THE OIL CAP AT THAT MOMENT AND THE NOISE WAS GONE. IT WAS THE PCV VALVE AND THE HOUSING(DON'T KNOW WHAT THAT IS) THAT NEEDED REPLACING. SO TRY UNSCREWING THE OIL CAP WHEN THE NOISE IS PRESENT. IF IT GOES AWAY THEN YOU HAVE THE SAME PROBLEM. THE PCV VALVE NEEDS REPLACEMENT. IF YOU CAN GET A GOOD, TRUSTING MECHANIC THAT CAN DO THIS FOR LESS THAN 350.00, YOUR GOOD. THE DEALER CHARGED ME 650.00 FOR THIS. GOOD LUCK.

1989 volvo 740 turbo


Check the tube from the air cleaner to the turbo, plus the intake on the air cleaner. It really sounds like something got sucked into the turbo. Best not run the car until you check it out! If there is a lot of smoke, your turbo is shot! Some can be rebuilt though! The high pitched sound could be your alternator. After you have checked the other things, remove the belt to the alternator, start the car, if the noise is still there, then let us know. OK Frankster016

Alternator belt replacement for 93 volvo 940


Preparation

Caution! Remove the ignition key.

Remove
the screw holding the engine stabilizer brace to the bracket on the engine
the screws holding the engine stabilizer brace to the suspension turrets
the engine stabilizer brace.

Applies only to B6xx4T engines:
Remove the plastic pipes between the turbocharger (TC) and charge air cooler (CAC) and between the air cleaner (ACL) and turbocharger (TC). Put them to one side. Remove the clamp from the intake manifold for the turbocharger (TC) for cylinders 1, 2 and 3. Turn the upper section of the pipe towards the firewall.

Relieve the load from the belt tensioner.
Remove the auxiliaries belt. See: Drive Belt\Service and Repair
Remove the upper timing belt cover.
Remove the front timing belt cover.
Lift up the servo reservoir and place it on top of the engine.Note! Ensure that the oil does not leak from the ventilation hole in the filler cap.

Seal the hose between the expansion tank and the radiator.
Disconnect the hose at the tank.
Lift up the expansion tank and place it on top of engine.

Raise the car. Remove
the right front wheel
the plastic nuts on the cover in the fender liner. Install the upper timing belt cover.
Turn the crankshaft clockwise until the markings on the crankshaft and camshaft pulleys correspond.
Turn the crankshaft a further 1/4 turn clockwise. Then turn back counter-clockwise until the markings correspond.
Remove the upper timing belt cover.

Remove the 4 vibration damper screws. Counterhold the crankshaft central nut.

Remove
the vibration damper
the auxiliaries belt
the belt cover behind the crankshaft pulley for the auxiliaries belt. Spray universal oil or similar around the rubber sleeve on the underside of the oil pump.

Remove the rubber sleeve.

Removing the timing belt

Slacken off the belt tensioner
Slacken off the center screw for the belt tensioner slightly.
Hold the center screw still.
Turn the tensioner eccentric counter-clockwise using a 6 mm Allen key.
Turn to 10 o'clock.
Unhook and remove the timing belt.Caution! Do not turn the camshafts or the crankshaft when the timing belt has been removed.


Checking the tensioner pulley and idler pulley Check bearing wear:
Spin the idler pulley and listen for noise. If replacing with a new idler pulley, tighten to 24 Nm .
Spin the tension pulley and listen for noise. When replacing, screw the tension pulley into place using the center screw.
Screw in the center screw by hand.
Ensure that the tensioner fork is centered over the cylinder block rib / bracket.
Ensure that the Allen hole on the eccentric is at "10 o'clock".

Installing the timing belt

Install the belt in the following order:
crankshaft
the idler pulley
intake cam
exhaust cam
water pump
tension pulley.Note! The variable valve timing unit on B6304S engines does not have a return spring. The unit is easily dislodged when reinstalling the timing belt.


Tensioning the timing belt

This adjustment is carried out on a cold engine. A suitable temperature is approximately 20°C / 68°F .
At higher temperatures (with the engine at operating temperature or a high outside temperature for example) the indicator is further to the right.
The illustration shows the position of the indicator when aligning the timing belt tensioner at different temperatures.
Carefully turn the crankshaft clockwise until the timing belt is tensioned. The belt must be in tension between the intake camshaft pulley, the idler pulley and the crankshaft.
Hold the belt tensioner center screw secure. Turn the belt tensioner eccentric clockwise until the tensioner indicator passes the marked position. Then turn the eccentric back so that the indicator reaches the marked position in the center of the window.
Hold the eccentric secure. Tighten the center screw to 25 Nm .
Check that the indicator is in the correct position.

Check

Press the belt to check that the indicator on the tensioner moves easily.
Install the upper timing belt cover. Turn the crankshaft 2 turns. Check that the markings on the crankshaft and camshaft pulley correspond.
Check that the indicator on the belt tensioner is within the marked area.

Finishing

Install the auxiliaries belt around the pulley on the crankshaft.
Install
the rubber sleeve on the underside of the oil pump
the vibration damper.
Use new screws.
Tighten to 35 Nm .
Angle-tighten 50°.
Use the crankshaft center nut as a counterhold
the plastic nuts for the cover in the right-hand fender liner
the right front wheel.

Lower the car.
the front timing belt cover. Tension the auxiliaries belt.
the expansion tank
the hose between the expansion tank and the radiator. Remove the lock grip pliers
the servo reservoir
the upper timing belt cover.

Applies only to B6xx4T engines:
Twist the intake pipe for the turbocharger for cylinders 1, 2 and 3 into position.
Tighten the clamp.
Install the plastic hoses between the turbocharger (TC) and the charge air cooler and between the air cleaner (ACL) and the turbocharger (TC). Tighten the hose clamps.

the engine stabilizer brace. Tighten to 50 Nm
the screw holding the engine stabilizer brace to the bracket on the engine. Tighten to 80 Nm .

Final check
Check and top up if required
coolant level
the servo fluid level. Test drive the engine.

Don't forget to rate the solution

thanks
good luck
