Ford - Ranger :: 1994 - Slight Knocking Sound From Engine Rod?
I've been noticing that my 1994 Ford Ranger 2.3L, 4 banger has a slight knocking sound. It is really faint compared to any other rod knock I have heard. An engine compression test shows mid 140's on all cylinders except one of them which is at 125. I'm guessing it isn't receiving enough oil. Can I prevent catastrophe by fixing this early on before a rebuild or replacement has to happen?

I know all Hyundai's 1.8L Nu engines have that quiet ticking noise. But is there a slight knocking sound on the left side of the engine (around the belt area)? Could this be just the timing chain noise? It does this on idle but when on a constant speed/rpm, the engine is quiet.

I have recently noticed that my Azera makes a "knocking" sound right after starting the engine. It just about a dozen of fast short knocks one after another and it is gone after 2 seconds (like a diesel engine started on low temp. It appears more often when the engine is rather cold.

A few months back, I posted a problem with my '01 prius: engine knocking for @30 sec when first starting up. Does NOT happen on first start of day, only on subsequent ones. Random misfires not corrected by changing coils/plug. It's been in the shop for awhile, and no diagnosis. I'm ready to sell the thing, unless there is a quick fix. New hybrid battery 20# miles ago; used transaxle 10# miles ago (with 1.5 yrs left on 2 yr warranty); new tires 10 miles ago. Has 185,000 miles.

The engine starts with knocking, rattling, and vibration that lasts for about 5 seconds. It seems to be an intermittent, rare event. With nearly 250,000 Prius in the North American market and the onset of cooler weather, it is time to see how frequently this occurs.

I have a 2007 sonata 2.4L with 93k miles that has a knocking sounds coming from the bottom of the engine. It seems that it is a bad rod bearing and was caused by low oil levels. I did not know that the oil was that low (3 quarts low) It started about a week ago. I know I'm gonna have to put it on jack stands and drop the oil pan.
By the way, Here is a video I found and it sounds similar to my car. Here's the link : 2.4L Theta Engine Noise - YouTube
Passat (B6) :: 2010 - Slight Knocking Sound - Is This Normal
I'm just starting to break in a new 2010 Passat and I hear some slight "knocking" noises at low RPMs during acceleration. It's only got 500 miles on it, so I am assuming it's just a characteristic of these engines; however, I've never owned a VW before so I don't know what is normal. this sound is typical for VW 2.0s? I think I have the PZEV version if that makes a difference.

Since about 5000 km, I have had a knocking metal rattling sound happening when I accelerate up a hill or a slight incline. It has happened a few times on flat road as well just more prevalent on the uphill battles. Now I assumed it was jus something loose that was rattling since I installed a cold air intake and had installed hid lights(I thought the ballast was banging on something). I tried and tried to find the rattle but I had no success. I read up on here about other people suffering the same problem and that running higher octane gas would solve it well I tried 89 and it was still there just not as much and I recently started using 91 and its gone haven't heard it at all.

Sonata NF (2006-10) :: Slight Knocking / Ticking Noise Coming Around Engine Area
It's a 2006 hyundai sonata LX.
Now Is it anything I should worry about? Car has 72000 on it. Always used synthetic Mobil 1 5w 30.
This is on a completely cold start up, 30 degrees outside. Only makes the noise until car warms up. Anything I can do to prevent this? Or is it not something to worry about? Should I just let the car warm up a little before I drive it?

Over the last few days, noticed immediately after starting car with AC on - slight mildew smell from the vents. Seems to last a few seconds then clears.
My Gen 3 is just over a year old with 10K miles. Live in Central Florida so the air has been on for plenty of those miles. Most times my HVAC is set Auto/75/AC on, and use no special procedures to vent the evaporator with non/cooled air prior to shutting off the car.
Elantra MD (2010-15) :: 2013 Hyundai 1.8L Auto GLS - Knocking Noise When Starting Engine
Weird noise I am hearing with my mothers new Elantra she just picked up. When starting engine has a knocking noise, not kinding. Letting motor run for a few minutes it goes away but is concerning. I was wondering if there is an issue with the MPFI engine which i believe is new this year which replaced the GDI engine. Definitely does not sound normal to me. to me it sounds like a rode knock or hydro lifter issue. Are these engines known for this. My mother traded her 2012 civic for this with 4500 miles. She did not like the seats and dash board layout in it and we got a good deal on this car.

I have a knocking sound from my D4EB engine (2008 Santa Fe. 120,000 miles)
Problem has been any diagnosis of the cause because the mechanics cannot agree. One has said top end and another bottom end. If it is top end when I think the consensus would be to get the present engine rebuilt. However, if bottom end then, because of the increased cost, the better option might be to replace with a reconditioned engine.
Sonata I45 (YF - 2011+) :: Repetitive Knocking Sound From Engine
I've got a 2011 Sonata GLS with 83k on it.
Last night I was driving and started to hear a repetitive knocking sound. Stopped to determine if it was only when moving but it continued in park.
Checked the oil and apparently there was very little of it.
Don't know how I screwed that up but the mechanic heard the engine for 1 second and said I need a full engine replacement.
So, yeah I am ticked off and need to take care of it.
The VIN qualifies for a replacement under the recall but I don't know how the dealership will feel about the present engine condition.
If that's not an option, where do I even begin to look for a replacement?
Sonata NF (2006-10) :: 2007 - Knocking Sound From Engine
I own a 07 Hyundai Sonata Limited with 31000 miles. It is 20 degrees today. When I start the car up there is this knocking sound from the engine. Once the car warms up the knocking sound only happens when the car is in drive or reverse. When the car is in park or neutral it is fairly quiet. The sounds is still there but not as loud as in drive or reverse. I have done the routine synthetic blend oil changes between 3500-4500 miles.
