Toyota - Tacoma :: 2001 - Engine Makes Knocking / Ticking Noise In Cold Weather
Dec 6, 2012
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.

The truck has 230,000 miles and has a squeal that sounds like a belt but it's not. I have put the truck in neutral coasted with the engine off and the noise is still there. The noise only happens when the weather is cold and only when the truck is coasting. Under acceleration the sound goes away.

My 2012 Toyota Tacoma's engine knocks around 1500 rpm, going up hill and does it 100% of the time in the summer. This I attribute running the Air Conditioning, but don't know for sure. The vehicle manual states on page 569 that the vehicle can take 87 octane gas. Also on the same page, there is a statement that says: "You may occasionally notice a light knocking for a short time while accelerating or driving uphill. This is normal and there is no need for concern." This seems very strange to me, engine knocking normal? I don't get it.

In the cold weather I found I had what sounded like ticking noise at idle on the R. It doesn't do it when first started and I didn't remember it in the warmer weather either. My research indicated it could be the DI injectors or the N80 valve. But what got me concerned was that I could hear the ticking inside the cabin, somewhere in the front passenger footwell area. And at times over normal radio volume. This was not the case in any of those other threads on the issue as they noted the sound only outside the car.
So I took the car into the dealer this morning to see what they would say. Had a good tech check out the car and try a few things. Turns out the tech found it was the fuel line underneath the car rattling. He said this was a common issue in the MK V cars and there is a service bulletin out on it, but he had never seen it on a MK VI car.

have an 2009 Toyota Corolla 62K miles. If the car sits out 8 hours or more in VERY COLD (zero degrees) weather makes a 1-2 second clashing/sparking noise the split second after turning the ignition on but before engine starts. I tried to attach video/audio. The car starts and runs fine. isn't a ticking or knocking or tapping noise assoc. with bad engine. It isn't squealing noise assoc. w/ serpentine belt. I've been waiting for it to get cold enough to leave overnight at Toyota dealer. I keep wondering if it isn't related to the botched oil changed at the Toyota dealer a couple yrs ago when they forgot the oil & I ran car about 30-60 seconds. At the time, they said all was okay and did compression test (Cyl 1=178psi, #2=175 #3=180 #4=178) all within the normal specs 145-189. I got a 2nd opinion at another Toyota dealer at time who removed valve cover and inspected cam caps and scoped cylinder walls and said all was okay and compression good. No mechanical problems- uses no oil, check engine light not on, etc. What noise is and why just when very cold and car sits out long time?

My mother and I own a 2001 RAV4 and over the past few weeks/couple of months we've had 4 instances where the car wouldn't start. Everything works - lights, radio, windows, etc. but when we try to start the engine it just makes a repetitive ticking sound and won't turn over. The first 2 times it happened the car eventually started but the second two times we had to get a jump. I suspect that there is a loose connection somewhere in the battery, but when it happened again the other day my mother got a jump and drove to the dealer for a look; the repairman said that the battery was fine and couldn't offer any other explanation for it.

When the engine of my 2007 Camry LE V6 is cold, it makes a ticking/knocking sound. The engine has 100,000 kms on it (60k miles). The frequency of the sound varies with the speed of the engine, not with the speed of the car.
When engine is cold: The sound happens roughly twice a second when the engine idles (at 700-800 rpm).
When engine is warm: The noise is less audible. It can be heard when idled at a stop, but you have to listen for it. The noise cannot be heard on the highway.
The car doesn't burn oil, and the oil level is ok. I had the oil changed 3000 kms ago, and it is still very clean (clear). The was the same before and after the oil change.
I am wondering if it could be the lifters, bad plug, or maybe a timing issue.

I just purchased a 2010 RX 350, has only 7k miles on it. Really, really nice car. I noticed for the first time yesterday the engine ticking/knocking/rattling/whatever you want to call it sound when starting up on a cold start. It definitely goes away after about 5-10 minutes of running.
Most people seem to accept this as "normal". They hear it, live with it, and they never have any problems. I am a new Lexus owner, so I have trouble digesting that such a luxury vehicle with so few miles would have a "normal" engine knocking sound at 7,000 miles.
A few people posted in other places that this is indeed an issue, and should not be happening. There is a a Toyota (Lexus) service bulletin that I didn't get the details on, it is LSB-0028-09. LEXUS: ENGINE TICKING NOISE AND/OR MIL ON P0014, P0015, P0024, P0025, P0017, OR P0018. ENGINE MECHANICAL. *PE
Looking for details on this service bulletin, and if it does indeed apply to the engine knocking sound.
- Premium gas
- High viscosity cold synthetic oil
- Dealer fixes issue
- Other fix?

I bought a remfg denso starter for my 2000 toyota tacoma prerunner 3.4L V6. I spent hours without success trying to get the old starter out. Brought it to a shop and had the new one installed. When I do a cold start, there is a screech at the end when the engine catches that sounds exactly like starting a car that is already running. This happens on cold starts only. Warm starts work fine. Due to the fact that I bought this part separate, having to pay to have a new one installed again is annoying to say the least. I spent another 4 hours today trying to get it out without success. See YouTube link for video of the noise. It's actually the quietest one yet.

it was warmer the day than it usually was so it dosnt make the noise as bad however there is usually a lot of clatter/knock from the engine when cold. does it at idle and while accelerating. it gets less once the engine warms up but has been doing it for a while. car has 93k miles and synthetic oil is used. there is also a metal rattle sound almost like a heat shield that is loose. idk if that is part of the engine issue or not. but it only happens in winter or when temps fall below 60 degrees. kinda hard to hear on the vid but its there.

I have a 2001 Toyota Sienna xle that started running rough when the weather turned cold. When started, the car idles very high and will not shift properly until it was been running for around 5 minutes. After that it will run well for about 10-15 minutes and then begin to run rough or poorly. The problem is very noticeable at low speeds and when stopped. It never actually kills, but it feels like it is going to. At high speeds it is less noticeable but occasionally you will feel it jerk or chug like the transmission is slipping or a belt or something.
I took it to a mechanic who checked the codes and found that the ignition coils were supposedly bad. I say supposedly because they replace three of the ignition coils and the problem still persists. I then took it back to the mechanic who then told me it was the oxygen sensor. The o2 sensor was replaced and the problem is still there with no noticeable improvement. I again to it back to the mechanic who tells me that they scratching their heads.
I have done some looking around on the internet and have found some discussions that seem to have some promising leeds and actually last weeks car talk show had a caller who described a similar problem. The guys told him it could be a oxygen sensor but they thought a better possibility would be EGR valve or a vacuum leak. Not sure if this sienna has an EGR, but I plan to suggest looking into it to the mechanic. Also, I found some discussions talking about the idle control valve and the engine control module.

I replaced my fuel filter on my 2003 2.4L tacoma 2wd. 65k miles. At the same time I checked the valves. No valve adjustment needed. Now I hear 4 to 6 rapid metallic clicks when i start the engine cold. Once it happened when it was warm. This fuel filter is not original equipment.

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?

I have a 2001 Ford Escape, and since the colder weather set in it is tacking below 1 and 'jumping' when idle. When accelerating and/or once the heat gauge has reach midway, the car is fine. I added a bottle of gas additive to the tank 3 weeks back, but the problem persists. The engine light is on but no code is registering.

Its been getting quite cold here lately at night and in the morning when i go to the santa fe it makes a ticking noise for about 2-3 seconds and everything is fine again. I was thinking of dropping a quart of transmission fluid in the crankcase run it for a bit and change the oil?

My engine in my 2002 Santa Fe 2.7 v6 has been making a ticking sound that was especially pronounced when cold starting. It would quiet down somewhat when warmed up but still a slight ticking would be there. I thought it was the hydraulic lash adjusters. I know Hyundai's service site sates that a ticking can be heard if the factory filter is not used. I tried using the factory oil filter which did not make a difference. The car had about 85,000 miles on it and I always maintained it well as well as keeping up with oil changes. I took it to the dealer to have a repair performed related to corrosion of the rear trailing arms and had the tech check the engine noise.
It was determined that the cam chains have developed slack and were slapping on the cam chain guides which prevent the cam chains from popping off in case of slack developing which was the case here. The chain guides are made of some type of plastic material and according to the tech showed significant wear. This was all covered under the powertrain warranty. For those that are not under warranty any longer and are capable of doing their own repairs this is the list of parts that was ordered by the dealer. The parts in red are the culprits. The rest are gaskets and seals. I don't think this is an easy job.

My 2005 with 160k miles has engine noise when cold.
I talked to a couple specialists who said it could be valve noise another said valve noise would not abate when the engine warmed up. He suspected piston slap. A valve adjustment is pricey and the local independents are afraid to touch it given the complexity and needed shim packs. If it is piston slap I would be disappointed after spending a pile of dough to still have the same noise.
Have I missed a possible cause?

I have a 1996 Toyota Tacoma, 5 speed manual pickup.
Occasionally I use the air conditioner. I'll be driving along and it's working fine but then it stops putting out cold air. I pulled into the mechanic one day and confirmed that when it is not putting out cold air, the compressor still seems to be running.
If I go into a store for about 15 minutes and then come out again, it works again. What might be happening?

After my car has sit for a couple of days, it doesn't like to start. By, " doesn't like to start", I mean it doesn't even click when the key is turned. I put a new battery in it but that didn't work. If I get it to start it seems to always start after coming out of a store (knock on wood). This only seems to be a problem after it has sit for a while.
