Prius (2001-03) :: Engine Knocking For 30 Seconds When First Starting Up
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.

Sometimes I have to park my car two blocks away in the afternoon, and later in the evening i need to park my car back to the spots in front of my apartment.
EV mode won't be enough to last the two blocks, even at 7 bars. Or sometimes the car won't let me turn on EV mode, even at 7 bars (battery too cold).
So the engine must run if i want to park my car back near my apartment. But the two block distance will not suffice to completely warm up the engine
So the next morning... (20~ Fahrenheit)
My car knocks for a few seconds the next morning the car starts up...
What is the definition of completing the warm up cycle? 120F? My car will turn off the engine after coolant temp reaches 120F (ECO mode).
Chevrolet - Blazer :: 2000 - Knocking Noise For 15 To 20 Seconds After Start Up
2000 Blazer 4wd, automatic, 122000 miles
In the last couple of weeks, if the Blazer isn't driven for 3 or more days, there is a slight knocking noise for 15 to 20 seconds after start up. Oil level and pressure are fine. I'm guessing it's the lifters.....
Prius (2001-03) :: Screeching Noise In Engine Bay Within 15 Seconds Of Starting
2001 Prius. Within 15 seconds of starting the engine, I captured the screeching sound from the engine bay. Noise went away after about 20 seconds. New serpentine belt and new 12v battery installed. Pass dealer 27-point check. Transmission fluid, inverter fluid, high voltage battery were replaced about 18,000 miles ago. Current mileage 174,000.
Noise is not from the serpentine belt. I attached a mp3 file of the sound. "2001 Prius Noise.MP3" ..... Which component is making this noise?
Prius (2010-12) :: Subtle Clicking Noise From The Engine When Accelerate
When I accelerate, particularly between the 50-60 mph range, the engine makes a very subtle, yet definite clicking noise. Mentioned this to the dealer - the car is still under warranty - and of course, they can't replicate the sound..is this common?

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.

2004 Santa Fe, 2.7 L V6. The oil was changed approx 5-7k miles ago (not really sure as I bought it from someone else) and I just changed it today. There's a new knocking noise in the engine. I used normal castrol GTX oil, 5w-30.
I drove it about 20 miles and the noise is still being made, so it's not a circulation problem.
Passat (B5) :: Subtle Knocking / Popping Sound Under Dash (Maybe From Climatronic)

Camry 2012+ :: 2015 Subtle Piston Slap After Start Up Of Engine?
Just purchased 2015 Camry LE. While taking delivery, I noticed a subtle piston slap that started shortly after the engine started and completely went away after driving the car for about 10 minutes. Most people would not consider it an issue, but I am an engineer working with large industrial engines all the time so it was a concern. I asked to drive another Camry on the lot and it had the same issue. The service manager came out and said that this slap is normal and all 2012 - 2015 Camry with 2AR-FE engine do this. I bought the car anyway since I loved the overall design, ride quality and the features, but the piston slap keeps bothering me.
2012-2015 Camry equipped with 2AR-FE 2.5L engine? In order to check you have to start the cold engine and wait for the RPMs to drop to around 900 which will take 1-2 min. Put your ear in front of the radiator and listed to the subtle metallic tapping noise of the pistons rocking and slapping the bore walls. The noise will last for about 10 minutes until the pistons expand and close the excess gap between them and the bore.
Ford Ranger / B-Series :: 2001 - Engine Swap / Knocking Noise For A While
I have a 2001 ford ranger 2.5 and a standard 5 speed. Its been knocking for a while now and recently its made a much lower tone knock, I am thinking I may have thrown a bearing. Also I am wondering what other engines I can use, besides the 2.5.....

Bought a brand new 2012 Prius in California - Power Toyota in Irvine. It was heavily raining so did not test drive. Package 3.Next day noticed that there was excessive road feel and buzzing like vibration.Took the car in and they noticed it too.
Changed Goodyears to Yokohoma, checked suspension and tire pressure. Issue did not go away. It is subtle but constant. Dealership said there is nothing wrong with the car and every car drives differently. Offered to change car with me taking a hit of 5000 dollars. It is like driving on a stone like rough surface with a buzz like vibration.Other cars I test drove did not have this. Two of my friends have 10 and 11 Prius they did not have the problem. They also felt the Buzz/Vibration in my car.
Ford F-150 - 1997-2003 :: 2001 - Occasional Knocking Noise Coming From Engine
I have a 2001 F150 4x4 4.6L Auto trans. 96,000 miles... I purchased it in Jan with 93,000. About a month ago it started making and occasional knocking noise coming from the engine, this noise was heard at idle in park and in drive. when I revved the motor it would go away but as the idle settle back down you could hear it again. the noise would go away as I was driving and come back with no rhyme or reason, I put a stethoscope on the engine and it seemed loudest under the oil pan. The oil gauge is up between 5/8 to 3/4. Fast forward to now, When I start it I hear a scraping almost grinding noise that resonated thru the cab it has the same intermittent characteristics. I think I am going to remove the serp belt, remove the trans inspection cover next and see what happens. Oh I did put a scan too on it, no codes but did notice 1 long term 02 sensor trim was staying around -.618 if I remember.

What i have noticed is that the relay clicking in the CECM is no longer clicking, yet now i hear this knocking in the rear hatch area when i start it up after it sits overnight.
Santa Fe (CM - 2007-12) :: Engine Start Up Noise For About 10 Seconds Or So
I recently purchased a 2011 Santa Fe SE with the 3.5 V6 Engine. When I start it up for the first time in the morning or after its been sitting for a few hours, the engine sounds likes it's insides are rattling for about 10 seconds or so... I believe the lifters are probably pumping up and it's a valve train noise... but is this normal? I don't like this sound. the previous owner used Mobil 1 synthetic oil and that is what is in there now. Is this a good choice for this engine? Is there an oil filter with a check valve that can be used to hold pressure to the valve train on start up? Is this cartridge type oil filter all that is used on these engines?

2006 Sonata LX. It's only on a cold start up and lasts for about 30-45 seconds tops..and then it goes away. Car has 74k on it. Treated well. Only use synthetic oil and no check engine lights. Last oil change I put 5w 30 in it. I know it says to use 5w 20. Could this be the problem?

I have a 97 7.3 ... I've had it about 2 months now and now it wont start! It will start and idle for 2 seconds then start knocking and die! I had a buzz test ran on it and all is good. I also checked my Icp and checked my uvch harness with my multimeter. Before this it would run ok but seemed like it had a miss and a lack of power. On start up if i didn't have it plugged in it would smoke white smoke horribly. I am thinking maybe my IDM. I need my truck for work .... I had it hooked up to a scanner and it said faulty IDM.
View 1 RepliesToyota - Tacoma :: 2001 - Engine Makes Knocking / Ticking Noise In Cold Weather
I have a 2001 Toyota Tacoma that has a knock or ticking in cold weather. The problem starts sometimes immediately after I start and other times it is only when I press on the gas in the cold mornings after a few min warm up. The noise goes away after 10 min. The question I am wondering is this:
1: could it be worn piston rings and the pistons are slapping the cylinder wall
2: is it an oil pump problem or a oil restriction issue
3: is it a valve guide issue
4: with the history of the 2.7 having exhaust manifold issues (poor manufacturing) could a cracked manifold be the issue
I change the oil myself, the oil filters have been OEM toyota, the noise has been going on since 60,000 miles, the truck is at 230,000 miles.

So My battery seems ok but the engine is running when I'm stopped a lot the last couple of days. I also hear a click from under the hood every once in a while like something is turning on.
Trying to even the voltage on a cell? I'm in SoCal but it's not hot or cold out.
