BMW :: 1999 - Noise Coming From Motor?
Aug 11, 2011
I have a 1999 3 series BMW, 115K, 5 speed, always used full synthetic oil, as did the previous owner. After a cold start, even at moderate/warm temperatures (65 degrees), for the first 2 - 3 minutes after the RPMs go over 1200 or 1300, I hear a noise from the motor, almost like a slight rattling/scraping sound of sorts, not very loud. The BMW dealer advised it is a known problem from new, and that the solution is a new oil pump. They advised that the repair is not necessary and to keep driving. My hunch is that the top of the motor is not being sufficiently lubricated after the cold start. I should further add that the car drives great, and I just took it on a 750 mile highway trip without any problems. The oil light always goes out, even on a cold day with a cold start, within 1 second after starting.

I've had this strange knocking noise ever since may coming from my motor. I thought, it might go away if i push the car a little. But it's been 6 months, and the thing is still going hard. What I'm experiencing is kind of a knocking noise, something akin to marbles being shaken up in some kind of jar, and it is only at partial throttle. Starts at 2000 rpms and goes all the way until redline. What it could be? Engine sounds perfectly fine at idle, power is still there. MPG's are the same... I've also read a couple threads that indicate that it could be my intake manifold, I am really not that good with cars, shameful but i admit.
Btw while i was browsing found a repair manual on the net [URL] ....

So i am looking to buy a 2007 Sonata 4 cylinder with 145K miles. There is a ticking noise coming from the motor. Sounds like a lifter tick. You can here it all the time even after its warmed up. I just don't know much about these cars.

About 2 months ago,we noticed a slight noise when first starting the truck in the mornings.The noise was so faint,I could never tell where it was coming from.The noise went away when vehicle warmed. This morning,I drove it for the first time in a while,and its pretty loud now. Its definitely coming from the front of the motor somewhere.I am thinking it sounds like bearings starting to go bad.When looking at the fan spinning from the side of the truck,it does not spin true,there is a very slight wobble. With the motor off and grabbing the fan in the middle,with force,I can very slightly wiggle it back and forth. I should NOT be able to do that,correct?
By the way,truck has 142,000 miles on it and the water pump and timing chain were changed at 117,000 miles.

I bought my 2006 Sonata with the 2.4L when it had 115,000 and it currently has 130,000 on it now. Ever since I bought it I noticed it had a ticking noise coming from the motor, it makes the noise constantly, it doesn't matter if the motor is hot or cold. I've always been a little worried about the noise. The car does runs like it should though. What it could be?

I have a 2015 Sonata 2.0T limited, and there is a noise coming from the back, driver's side, after shutting off the motor. I've taken it in 3 times for this, and each time they say nothing is wrong; but, I've driven a lot of cars and trucks, and I've never heard a noise like this.
I'm guessing it's some kind of gas tank related valve that's closing, but it's making a very loud noise each time.

I have a 2010 ford f150 with a 4.6 engine. it has developed a loud noise like a diesel on steroids and also sounds like its going to fly apart and it also misses when it does this . now this is how I have narrowed it down to make it happen because it does not do it all the time. it mainly does it to and from longer trips like 45 minutes or more then coming into traffic to a crawl or idle it will start making the noise . also when I pull into my drive and go from drive to reverse and go to back up it will also make the noise. I have no lights on the dash or codes. could this be a coil pack ? I had a coil go a few years back but it acted up under load on a hill and just missed with no noise.

I have a question about my 2007 F150 4x4 with the 5.4L. It has a ticking noise sound coming from somewhere around the motor, but it's not there till the motor has warmed up. It almost sounds like a exhaust leak, but I'm not sure. What it might be, or what to look for?

Last night when I went out into the garage, I heard the sound of a small, lower RPM electric motor. After walking around a bit, I found it coming from the underside of the back of the Camry. I got in and turned the key to the "on" position and it went away. The car had been parked for about 5-6 hours. I've never heard this noise before.

I have a 2013 ES 350. Last night about 5 hours after the engine had been turned off, we noticed a strange noise coming from under the rear of the car? It sounded like a small electric motor was running. I started the car and turned it off. The noise had quit. This is actually the second time this happened.
I got under the car to try and determine the exact location of the noise, It sounded to be coming from the gas tank area. Could it be a fuel pump kicking on?

Started getting a noise a few minutes after startup. I can hear it click on and then it sounds like a loud electric motor/pump/fan type noise. Starts pretty loud, then gets quieter (but not gone) after 30 secs. If I turn off the engine, it stops and if I immediately restart, it's gone for a couple minutes.

Been driving my Sonata 2015 2.0t for about 14 months, now. Just turned 13.5k miles. I had first noticed this issue a few months into having the car, but didn't think anything of it. At the time, I wasn't spending much time in the upper end of the rev range. Today, I finally decided that it bugs me enough to investigate.
At WOT, starting around 5500 rpm and going until redline, there is a "raspy" sound coming from the motor that I think might be predetonation, but I'm not sure. It isn't very loud, which is why I originally ignored it, but it is easily noticeable inside the car. I've made some modifications in the past few weeks (Intake, OCC, and Exhaust) so I'm starting to have a bit more fun with the car and want to make sure I get this resolved before it becomes a bigger issue.
Out of curiosity, I looked inside the catch can and noticed a couple drops of fluid (lighter in color), which was surprising since I only installed it ~50 miles ago. Any by "a couple drops" I mean maybe 3mL of fluid. Not sure if that is significant in this case, but I figured it is worth mentioning.
I'm wondering if it could just be the altitude (Denver, CO) and the stock tune is off just a bit? I've been looking into the Lap3 Uncle Chip and HKS performance plugs, but am hesitant to go any further without better understanding what might be happening.

I have a 2014 ES300H that I just purchased. After driving around for a while I parked it in the garage. After it had been sitting in the garage for around 6 hours, I hear a motor or fan type noise coming from the trunk area. It lasted for several minutes and then stopped. Is that normal and what the noise might be.

I noticed that I have an unusual "rumble" noise coming from the location of my ac blower motor when it kicks in full blast. When the air temp comes down a bit and the AC slows down or if I switch the ac off full blast under climate control, the noise goes away. I have never noticed this before and am wondering if it is my ac blower motor starting to fail.

I have a 97 250 LD 5.4 that suddenly has a grinding noise coming from the area where the transmission and motor meet. I took the inspection plate off the transmission and can look up inside there and see everything moving. I use a screw driver and if I flex the plate that mounts between the transmission and the motor I am able to get the noise to quiet down until I release the screwdriver and then the plate flexes back and scrapes making the noise again.
I can not see where the plate is grinding when I look up inside there. I can't figure out how to fix this.... Why it would just start doing this on its own as none of the bolts on the housing have been removed except for the two bolts that hold the starter on. (Changed it a couple of weeks ago). Thought about loosening the bolts on the tranny housing but I'm afraid that it would open me up to further problems???

The truck always made a few strange noises after shutdown, but this is new and annoying.
Here's the scenario: Truck is warm and no CEL. A few seconds after shutdown, I hear all the normal(?) noises and then a noise that sounds like a vacume pump running starts and continues for about 20 to 30 seconds. Cycling the key, but not starting the motor will cause the noise to happen again and again on each key on/off cycle.
The noise seems to be coming from the top front of the motor. Could this be fuel pressure bleeding off? Is there a check valve that is maybe not doing it's job??

Faint humming/whistling noise coming from the drivings side of the motor. I can hear it when I put my head next to the drivers wheel well, and most certainly from that side of the motor when the hood is popped. It's not super loud, but it is noticeable. I know we have Direct injection motors, so I know that ticking is completely normal. Am I overlooking this and being paranoid? Car has 2100 miles on it. I don't know if it was there when brand new.

I have a 2002 F350 Triton V10, Automatic 4x4 Lariat. I have a tapping noise in my motor, and I've had people tell me it could be the timing chain slapping around, a rod or lifter. The tapping noise gets quieter after the motor has warmed up, but gets louder when given gas. I've been told to try thicker oil, pure gasoline (no ethanol), The truck runs fine for the most part except for a vacuum leak on the top part of the motor underneath the throttle body. I have someone that says they can work on the motor and so on. But I don't know where to look to buy the parts for the motor, and what I should have replaced, while he's got the motor out and apart, so far he said he'd change the lifters, timing chain, the vacuum leak.

I have a 2003 super duty V10 4WD super cab long bed.
loud deep rumble noise when turn on the blower. both heat and a/c. removed the blower and seemed to turn ok. blew out all vents. removed heater radiator cover, checked most flaps to see if working. doesn't seem to be obstruction invent. the flap behind blower clear and functioning ok.
When on second speed, almost sounds like blower motor is out of balance. if run on high for 1 minute, smell electrical burning! Think to replace motor will work? will post another issue with radio and power windows
