2006 Toyota Camry 2.4L (2AZ-FE) 5-spd (U250E) — 4T1BE32K36U132046

Good Afternoon everybody, this Toyota Camry has a whining noise that in in sync with engine, removed belt and check all pulleys and ok, turned engine on and noise is present and rises and falls with engine speed, only place I can think of that would make a whining noise from inside engine is the balance shaft, but the vehicle has only 38k miles on it and looks well maintained, family member replace alternator to no avail, water pump has dried antifreeze on it but it must be internal and the balance shaft is sold with the upper oil pan which has to be timed, just never heard this noise from a low mileage Camry…..

Water pump can make a noise how you described. If it has dried antifreeze it would be worth it to change it. Got fooled by this before. Even changed to alternator too Sorry missed the part where you said the noise was there with the belt off

Perform an Active Test on the VVTi actuators and see if the noise changes. If so, could be coming from there.

Hello Bob, tried the VVT actuator and it just stalls the car and the noise goes away as vehicle is no longer running….while giving it gas it stays with the same sharp whining noise..

You indicated noise was loudest behind the crank pulley. sounds like an oil pump.

Same idea here, just waiting on client to ok timing cover removal, possible tensioner for oil pump chain… was also going to remove oil pan and see if pick up was plugged with sludge and making suction noise, oil pump is run off a chain from crankshaft, maybe clearance issue or it is the gears in the balance shaft either off like the camshaft gears on the v6 that had to be pinned together with a…

Hi Sean, I would use a mechanic stethoscope and see if you can pinpoint where the noise is the loudest. A section of heater hose and a long plastic funnel also works very well because it will amplify the sound. I would make every effort possible to pin down where it is loudest before conductive intrusive exploration. At this age, I would not use mileage as a marker. I have seen many cheated…

Hi Glenn, looks like the noise is coming form behind the front crankshaft pulley, the noise diminishes when you go towards the transmission side, loudest behind the crankshaft pulley, looks like I am going to ask for timing chain cover removal to get to the bottom of this noise if it is palatable to client. Could be the oil pump chain hitting against the side as well, from all the chatter on the…

An over tightened timing belt can cause this if it’s a 4cyl. Just remove the rubber plug and loosen the 14mm bolt then retighten. If it’s too loose it can cause a flapping sound due to the belt slapping the timing cover. It takes an “experienced feel” to get it just right. Never mind, just saw the year and engine. Has a timing chain.

some of the Camry 2.4 engines had a noise issue in the intake manifold, check that area. replacement manifold solved a few for me.

Hello Gary, I have a replaced a few intake manifold for clattering noises but this is like a sharp whining noise from a failed alternator and seems to be coming from behind the crankshaft pulley which is at its loudest…

Does it have excessive crankcase vacuum? I've seen a few vehicles make noise as air is drawn in past the front and/or rear crankshaft seal. Try removing the oil dipstick or oil fill cap while it is running. Careful with the cap, it may blow oil all over with it completely removed.

Hello. Check with mechanic stethoscope , the chain of oil pump with 2AZ never had a problem ,i fixed many time the balance shaft if you have this problem you feel vibration in the car , maybe it's a chain problem

Hello Wissam, usually the vibration is present but this one does not have any vibration, just high pitched noise behind the crankshaft pulley as far as the statoscope can hear, but noise propagates through the block and hard to tell exactly where with the engine running with no belt on the car, just waiting for a tear down reply before I get into it, thanks, some people say just to delete it but…

Hello Sean, It is apparent that some people are not reading all of your post. It is great that people want to help, but they need to slow down read the details, and read the other replies to get a full picture of the situation. I admit that I have been guilty of that in the past and have to catch myself from time to time. The overpowering feeling/ driving to help others can make anyone jump to…

Well, removed the timing chain cover, removed timing chain and oil pump chain, thought the oil pump drive gear on crankshaft had play but that is just the way they are made, the key hole is bigger that the keyway, i am sure for a purpose, next have to get in the oil pump or balance shafts and see if the nylon gear may have a wear issue….
