I have a f150 with a 5.4 triton I have noises coming from the engine loud when cold get quiet as you increase rpm almost sounds like the valves if you go under truck noise gets louder truck has less than 68000 miles.
View 2 RepliesThe wife drove the Excursion (V10) to work today and it ran normal and didn't have any loud noises coming from under the hood. When she started the engine to return home it immediately started knocking. This is not a ping, but a knock. Not a loud heavy knock, but much louder than a ping. It has a fast frequency, seems too fast to be a rod knocking. The frequency is similar to a valve issue, but the knock seems to be too heavy for lifters. Oil looks good. Just changed out 2 weeks ago. Truck is driven everyday.
View 11 RepliesI bought a 2008 5.4l xlt about a year ago now. For the first time I took it on a trail that had a little mud. With my incredible wisdom, I decided to park the truck rather than wash it off. The next day the engine started making weird noises when I turned the steering wheel. After washing the truck it still made noises so I opened the hood. THE ENTIRE engine compartment is covered in a serious amount of mud. I feel that this has to be what started the noises when I turn. Mud dried in the wrong place? The noise sounds like a whine and its pitch matches the engine rpm until over 2500 where I don't really hear it anymore. Is there a way to flush the engine compartment?
View 7 Replies5.4. So I have a 2004 F-150 that just passed 80,000 miles and a month ago it started making a very loud noise on startup, but only cold startup, meaning if I haven't used the truck in about three hours. Now I went on youtube to research and found a video of a truck making the exact same noise! Here is the link:

Need to verify what this is??? Some people are saying cam phasers and some are saying I'll need a brand new engine!
I have a loud tapping noise in my 07 5.4 triton. when its really cold on the first start up I cant here the noise but when it gets warm its tap tap tap again.
View 4 RepliesOk it's kind of hard to explain, but I have a 05 f150 fx4 5.4. Recently only when the motor is cold I will give it gas from about 1000 rpm and get a loud pop. Is sounds like its almost coming from under the drivers seat. After that is fine. I could almost make it do it on command now. But once it's warmed up doesn't seem to do it. I want to fix this. I was thinking possible backfire?? Spark plugs maybe??
View 4 RepliesSo I was at my friend's shop today getting something done and since I wouldn't have to pay for it, I had him hook up the OBD scanner. Turns out the check engine light I've been having sporadically show up is P0420. After getting this, I had the sinking feeling of knowing finally what the problem was. Recently I've been having some very loud noises coming from my exhaust, and not from the tips where it should be. So we jacked up the car, and what do I find? The connection right behind the catalytic converter where it connects to the rest of the rear exhaust was compromised. Apparently I had scraped the exhaust a couple times too forcefully and it separated at the flange and the gasket is no longer sealing. So here's my question. I have the TRD CAT-back exhaust. Is there a generic universal gasket that I can use to replace the leaking one? Or am I looking at needing to find a shop to make one?

View 7 RepliesSome family members borrowed my truck, and when they returned I have a loud whining noise coming from the rear axle, which I have determined is a 9.75 rear. I checked oil level and it was high enough, but has a slight leak from the pinion seal. Everything feels solid but I have nothing to compare it to.
Its on a 2005 Super Cab with the 5.4L 183,000 miles. The front pinion seal was replaced in Feb 2 years ago, by the dealer's mechanic, who may have been a shade tree mechanic.
I am a Youtube Certified Mechanic, as in, I watched about 10 videos of people working on their 9.75 differentials, and realize I don't have all of the tools to do the job, such as a press, or race drivers, or the special gauge.
How many of you have tackled this issue? What did you find? What am I looking at for cost? I am on a very small budget.
I've a loud squeaking sound coming from the front of the engine on cold start. This only happens when I start the engine after overnight parking . There are no squeaks when the engine is warmed up or when I start up with a warm engine.
I'm driving an 07 Camry and live in a region with hot tropical weather.

What could be the probable cause of the this and how do I rectify it?
I am a proud and recent owner of a 2015 Sonata Sport 2.0T!
Car looks amazing and am very happy with it.
But lately I have been noticing lots of drone noise coming from the engine, and a really loud cold start as well. The "cold start loudness" goes away after a little bit of driving.
Was wondering if this is just the way the 2.0T sounds, or should i get it checked?
I have a 2007 F150 with a 5.4. I am having an issue with my A/C and more.
Here are the symptoms:
1) A/C doesn't blow cold, at times.
2) Compressor not coming on, according to mechanic.
3) Engine sounds like a freight train, at times. Like on a super cold day and it has to work hard.
4) Very poor fuel mileage since this started.
I took it to a shop, and they said it was the engine cooling fan that would not come on. So I replaced it. Same issue. I then took it back and was told there is a wiring problem. After 3 days they couldn't find it. I needed my truck back and dropped it off again. Then they said it was the A/C compressor, maybe. They wanted to try it and then see what happened. I told them no way.
Temperature, according to the gauge is good. Noise comes and goes. Not dependent on anything. Weather, temperature, car heated up or dead cold. Just comes and goes.
Loud engine grinding noise accelerating from stop when you first start the car? It is right after cold start, lasts 10-15 seconds until I get to 30-40mph. Engine sounds normal otherwise.

I have a 2006 Subaru Outback. When I start it, it makes a constant rather loud rumbling noise that seems to be coming from the rear of the car. I can feel a little vibration through the steering wheel, but when I put the car in neutral the noise/vibration goes away.
View 10 RepliesI have a 2008 Ford F150 that ticks loudly at hot idle. Took it to the dealer and hear is what the service manager has said so far:
"So far we checked codes, all was ok. tested oil pressure and found it met the spec of 15 PSI, removed valve covers. Found the CVT solonoids are the newer style. Inspected the camshafts, cam phasers, rocker arms, cam chains. All check ok at this time. Not finding any true "root of concern" I'm trying to get approval for engine replacement in hopes that replacement is quieter. Approval is difficult without any true failure...still working on it though."
If this is not the cam phasers, what else could it possibly be?

I have an 04 mountaineer and when i shut it of i get a loud banging noise from it. Its sounds like its coming from the engine compartment. The truck itself runs great and I didn't see any exhaust leaks. It has 70,000 on it.
View 2 RepliesMy awesome 1990 Toyota Pickup (6 cyl., supercab), fondly named Ol' Rusty, has a measly 245,000 miles on it and still running strong. The one problem is that when it is very cold out such as this morning (-10F), I get a terrible noise coming from under the hood just in front of the steering column. It sounds like a belt rubbing, but I can't find it. It happens when I start going faster than 20 mph and goes away once the engine is completely warm. When it's happening, the speedometer jumps a bit. Interestingly, if I warm the truck up for 10 minutes or more so that the engine is completely warm, it still happens when I first drive the truck. Is this something I need to worry about or can I continue to ignore it like I have been for the last 3 years?
View 2 RepliesTrying to find any information on what's happening with my 2008 2.2 Diesel Santa Fe ... Been driving fine until I pulled up at a set of traffic lights yesterday and started hearing a loud rattle- knocking coming from the engine at idle.
Put it in gear and drove and it goes away. When at idle if you rev the car it goes away.
Mechanic seems to think it could be clutch as it vibrates the gearbox, but sound seems to be more prominent around the engine, my thoughts were maybe a loose timing tensioner.
Clutch replacement is very expensive.
I have a 2005 STX with the 4.6L, 4WD, AT.
The engine has started to make a loud whining sound recently. I replaced the belt and tensioner since it was original and had 93,000 miles on it. The sound is still there.
The sound increases with rpm but doesn't change when you turn the steering wheel.
The engine starts and runs smoothly with plenty of power.
My new to me 04 4.6 shuddered and misfired really bad last week, got couple misfire codes. I changed plugs which were really bad, like burnt out to .080, got a HEI ignition tester and got a healthy spark from all the coil packs. Drove it today and ran much better but still would shudder under acceleration when cold, wasn't as bad when warmed up but still noticeable. I thought if I got a spark with the tester that means the coil is ok? or is that not the last word in coil health. Or should I look somewhere else like injectors ? Haven't got any codes since plug change.
View 1 RepliesOur 46K mile 2012 Tiguan starting making some pretty loud whining/growling/rattling engine noises recently so I took it to the dealer shop and they diagnosed a bad accessory belt tensioner. However, they didn't have one in stock and would have to order it. Well, that's fine but it's a 300 mile round trip to the dealer so I came home and ordered one from ECS Tuning.
I found a copy of an official VW (ETKA?) procedure on the web for replacing the tensioner for the TSI in a Golf so I suspect the procedure for a Tiguan is similar: remove the bolt for the secondary water pump and move the pump out of the way, remove the end bolt on the tensioner mounting shaft, remove the three bolts from the pendulum/dogbone, support the engine, remove the top two bolts from the passenger side engine mount, drop the engine about 2 inches and pull the tensioner out.
To be honest, I was very surprised that the dealership didn't have a tensioner in stock. This was a rather large and pretty good dealership shop (three service advisors). I guess accessory tensioner failure is really rare on the TSI.
