I have an 06 volvo s40 with a 2.4l non turbo. When I reach about 2200 rpms I hear the valves tapping. When I put the car in park and rev the motor up the valves don't make any noise. Where to start.
View 6 RepliesLooking for info on reseating the valves on a 2004 camry four cylinder. My car has 95000 miles on it right now and you can hear the valves tapping I guess making noise .
View 14 RepliesTruck was running fine all day then as I pulled into the driveway the service engine light came on. Did a scan and code says , intake manifold runner stuck open bank 1. I was told they are at the back of the manifold but I can't even get a mirror in that tiny space. What is involved in reaching these two valves and how do I know which is bank 1?
View 1 RepliesI just bought a 2012 hyundia accent automatic two months ago with 92,000 miles on it. I put everything i had down on it so now I don't have a lot for warranty co-pay or anything. After two weeks of owning it i got a P0420 code and a light tapping noise. Well i was going to work (i drive up and down mountains) and when i headed up an incline my rpms jumped from three to five and lost all speed. I pulled into rest stop and was freaking out. Anyway after about an our of me looking i decided to just shake my car back and forth. I got in and pulled back onto interstate and the car was fine..except for a baffled sound now with light tapping. I cant figure why after it cooled it ran ok. Makes me wonder if i had bad gas or something. Well fast forward one month and now i am throwing P420, P0011, P0326,and using one quart of oil every 300 miles. I have done the oil change, injector cleaner, airfilter. I am gonna change the pcv valve today and see if that works.
View 4 RepliesI have a new to me 2009 matrix. I have noticed that the RPMs at around 2,200 when driving in town at 40 MPH then after a few minutes they drop to 1,600. I know I'm wasting gas running 2,200 RPM when driving at 40 MPH so I have started putting the car in neutral then quickly back into drive and the RPMs are at 1,600. I am also putting the car in neutral as I come to a red light or stop sign RPMs drop to around 900.
View 1 RepliesI feel my 2009 Sonata with 25k miles has a fast startup idle.
It goes upto 2200 RPMs. It runs fine otherwise.
I will keep an eye on it to get more RPMs and timing.
I have a 2006 Sorento, Idle at start, when cold is 2000 to 2200 rpms. When engine warms idle comes down to normal, 1000.
Replaced several vacuum lines, none showed any leaking but replaced to be sure.
Replaced the PCV valve, the old valve was not closing as it should and the replacement seemed to work some.
Replaced the Idle Air Control Valve and checked the old one for movement, moved an 1/8 of and inch from when cold to when hot. The new IAC did improve the problem some.
Tested throttle position sensor voltage, was good through range of motion (including being tapped on to simulate the running of the engine).
Sprayed carburetor cleaner around the engine when cold to look for a possible manifold leak, nothing noted.
Noticed one area that brings down the high idle when sprayed with carburetor cleaner is in the front top center, around a small plastic cylinder which is part of the intake system and has a vacuum manifold which changes the position of the cylinder with engine operation. I have two pictures of the area attached, the white cylinder is at end of paint stick, the vacuum manifold is to the right of the paint stick and yes there are vacuum lines not hooked up in the pictures. Hoping this is not a manifold leak.
Ok, I was driving down the interstate in my 2002 Ford Escape XLT 4X4 and I noticed my rpm's reved to about 5000 from my cruising rpm of 2200 and it was as if it went into neutral. I coasted with engine running fine to the right shoulder and called a tow truck to the nearest dealer. No reverse, D, 2 or 1 only Park that worked.

View 5 RepliesI recently bought a 97 960. i have had a s90 before in totaled it i loved the car so much i found another. i was driving and broke the timing belt tensioner which in turn lead to the breaking of 5 exhaust valves that i know of. I've taken off the head and noticed that one of the bottom of the valves had melted onto the number 5 piston head.
I called around and search but every motor is at least 1000 and i have been told anywhere from 3500-4500 to rebuild. My question would b is there an easy way to fix or should i junk it. i bought it for a 1000 it has only 140000 on it an its in almost great condition. I attached some pictures of the head and piston so u can see the damage.

Is there truely no cure for exhaust flutter on a 2002 f250 V10, bedsides putting on headers??? I have the the sound at shift points around 1800-2200 rpms. Sounds great before and after these points....
View 14 RepliesI have a rattle coming from the muffler when I reach 2000-3000 rpms. I thought it may be the heat shied, so I got underneath the car and it was nice a snug. Had my wife get in the driver seat and rev the engine. It seems as though all sound came from the outlet of the muffler. Do I have an internal failure in the muffler? Over the past month it has become louder.
View 2 Replies-My pickup was parked and hit in the rear axle in January. I had to have the whole axle replaced as well as the leaf spring to frame mounts.
-I finally received the pickup back and now when the trans is in Drive it will not up-shift until the rpms reach 2500 and it is a hard shift.
-Also the speedo does not work now.
-Check engine light also came on with code P0500- vehicle speed sensor.
-I replaced the VSS at the transfercase and the ABS sensor in the rear differential with no change.
I have a 97 3.5. A few years ago something in the drive train started vibrating/resonating strongly when the engine RPM's reach about 1800-2000. I can feel it most in the gas pedal but it also resonates through the dashboard and sometimes makes the dash cover buzz. It didn't start out faint and get progressively worse, just started one day and has been there ever since and hasn't really gotten worse. Actually started after replacing my plugs, wires, intake gaskets, and valve cover gaskets. I originally thought engine, then I thought maybe it's in tranny, but it's worse when a/c is on although compressor is quiet and works great.
More info: has 198k, runs like a champ, no hesitation; tranny replaced @ 104K
03 Xterra makes whining noise at 2200-2500 rpm. Noise goes away outside this range. At 3000 rpm sounds like tachy cable rattles. Have had Nissan check trans, diff, muffler. No luck.
View 1 RepliesII had the vibration/hum for the first time when you reach 70mph and I need to know if it is safe to drive for about a week. I have looked but can't seem to find the answer.
View 8 RepliesSometimes when I start my 2010 camry with the 2.5L, it makes a noise on the top end like there's no oil and the valves are very loud and a second or 2 later it goes away, is this normal....
View 1 RepliesI have a 2004 V8 with 27k I have noticed lately that the valve noise seems awfully loud. I am sure this can't be normal. I am going to take it to ;the dealer to let them listen. I can hear them now telling me that is normal.
View 24 RepliesWhile I drive my camry I can hear a noise from the driver side. Together with the noise the car also vibrates. My bottle of water and all other loose stuff in the car rattles. It start to happen when I reach about 25mph. Then the faster I go the louder it gets. But once I past 60mph it won't get any louder. Stay at about the same level all the time. Is it wheel bearing or wheel balance? To me it sound like the wheel has a small bulge or something.
View 12 RepliesMy 2006 f-150 with 71,000 miles has been making a groaning noise in the front when I reach about 20mph and it will intermittently stop for a few seconds and then start again. And when I turn left it completely stops. I have had it to my Ford dealership three times and they replaced my steering shaft and brakes and checked for anything rubbing and have not fixed it. I'm worrying about this every time I take a trip.
