    if valve work is needed to purchase a new or rebuilt head from the dealer or have the existing head rebuilt.
    Had to chuckle on that one. Personally, if the noise is tappet noise, then you may want to find an Import shop that specializes in Volvos and ask them how much they would charge for diagnostics on the noise.
    Then go from there.

    As for the heads, if the tappets are the noise problem, then resurfacing the valves and seats and new seals should be the only thing needed.

    The problem is, until you know for sure where the noise is coming from, there are too many variables to even offer suggestions on it.
  • I had the same problem with my 95 Firebird V6. It was a clogged Catalytic Converter. Some people fixed it by pulling it out and chipping out the charcoal-like bricks inside - the engine ran 100 X better. Then some people went ahead and forked over the wopping $406.00 dollars to the dealer and bought a new Catalytic Converter. Being as I didnt make much to afford it - you can guess which option I took. ;-)
  • Depending on where you live you may or may not always be able to get away with doing that to your Converter.
  • I would know how i can see all the Technical service bulliins on my car just as the mechanics at the dealers do. Help me

  • During cold weather, it seems that the parking brake freezes and the rear brakes drag for a bit. I took the car to the Ford dealership and they could find nothing wrong with the rear brakes or parking brake. Keep in mind, this visit was in 2007 and I just found a TSB issued in January, 2006 that apparently addresses this problem. If anyone has experienced this, or has a full summary of the TSB, I would appreciate any help!!

    TSB 06-5-4
    2005-2006 Mustang
    Some 2005-2006 Mustangs built prior to 10/1/2005 may exhibit park brake cables that freeze in cold weather due to water intrusion, and subsequently not release. Under some conditions this could lead to dragging rear brakes. The rear sealing boot on the cable (located at the rear caliper attachment) could deteriorate prematurely which may permit water intrusion. In freezing temperatures this could bind the cable inside the casing, and not allow tension to be released from the caliper.
    Inspect the park brake cable and system components. If the rubber sealing boots show signs of deterioration, replace both rear park brake cables.

    It should be free, assuming this is the problem.
  • Unfortunately the warranty was up just a few miles ago...
  • 210delray210delray Posts: 4,722
    Yes, but TSBs are normally no-charge repairs.
  • 0patience0patience Oregon CoastPosts: 1,622
    Yes, but TSBs are normally no-charge repairs.

    NO! They are NOT!
    TSBs are NEVER no-charge repairs. Unless the vehicle is under warranty.

    You are confusing recalls with TSBs.
  • 210delray210delray Posts: 4,722
    Really, I thought if a TSB was issued for your car, and you came into a dealer complaining of the problem addressed by the TSB, it would be taken care of, gratis (regardless of whether the warranty had expired). I realize this is the case with recalls, but I thought TSBs were handled the same way.

    If not, my bad. (On reflection, I've never had a TSB performed on my cars out of warranty.)
  • 0patience0patience Oregon CoastPosts: 1,622
    A TSB is a technical information bulletin.
    It is designed to address "known" problems that certain vehicles exhibit.
    Some problems are ones that are because of manufacturing defects (which I will agree should become recalls) or because a part has become out dated.

    It is designed to assist the manufacturer's technicians in repairs. Some TSBs are informational only. They may be updated service manual pages or specific procedures that aren't normally done.

    In the past, a lot of folks considered TSBs as a cure all, which isn't really the case.
    They are a wealth of information, but only if you know what you are looking for.
    Never assume that the TSB is THE answer, because a lot of variables, such as VIN number, production date and place of manufacture can tell you if the TSB applies to your vehicle.

    A person should always be careful when they assume that the TSB pertains to their vehicle, as they could spend money unecessarily, if they haven't researched well enough.

    Hope this helps clear things up.

    Also a dealer is in no way obligated to perform the tests or procedures recommended by the TSB for your car.

  • My wife leased a 2007 nissan altima. We have not had it more than 9 months and it has been in the shop 8 times for the same reason. The car was dead this morning.
    She sets the auto headlight feature on the car. The last time she took it in they said they replaced the, "light sensor unit", and the problem would stop. Wrong.
    The car I believe has 7000 miles on it (oil was changed 2 weeks ago). She wants to return it as a "LEMON".
    She kept all documentation regarding this problem and the issue.
    Does anyone out there have any knowledge of this problem with the 2007 Altima?
    Also, does she have a case with the "LEMON" situation of the car.
    My wife explaind to me she had received last week a recall on a "on board emission computer problem". Guess it senses a problem with the catalytic converter and a light will go on (she has an Official Nissan recall letter). When talking to the dealership this morning they first had no knowledge of this recall and was also told that this may contribute to the problem she is experiencing.
    They told her to tow the car to the dealership.
    Need your guys help...

    Nope I checked all the TSBs and recalls and no mention of dead battery.

    Every state has different lemon laws. You need to check the laws in your state.

    Has anyone seen this TSB? It has to do with the ABS improperly setting codes 35, 36, or 37. What I'm interested in is whether or not it describes what a customer complaint might be? Have 35 and 37 set on my 96 Suburban.
  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 57,602
    This is the only similar one I found in the listings. Perhaps your number is not a GM number but a NHTSA number?

    This shows as a GM TSB # 1539013

    Subject: SES Light and P0300 When Towing, Cruising Uphill or on hard Acceleration - kw 4.3, 5.0, 5.7 accelerate cruise cylinderhead DTC L30, L31, L35, LF6, LU3, P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0307 P0308 # PIP3081 - (07/23/2004)


    The following diagnosis might be helpful if the vehicle exhibits the symptom described in the PI.


    The vehicle may exhibit a SES Light due to a P0300 and misfire. If the misfire is related to the information below, it will typically happen while cruising uphill, pulling a trailer or on hard acceleration and then stop misfiring shortly after returning to an idle. Typically, cylinders 3, 4, 5 or 6 will be the ones to experience this.


    If the P0300 SI diagnostics did not isolate a concern, the following may help:

    Remove the valve cover, valve springs and valve seals on the effected cylinder or cylinders. A small wire tie or rubber bands can be placed in the valve stem keeper groove to prevent the valve from falling into the cylinder. Rotate the valve while moving it up and down in the guide to see if it binds. If a binding valve is found, remove both cylinder heads and use either of the following methods to increase the stem to guide clearance:
    ^ Send the head out to a machine shop and advise them to increase the valve stem to guide clearance to 0.002 inch per guide.

    ^ Hone the guide with a 9 mm hone, such as Snap On BCG249, until a clearance of 0.002 inch is obtained. This will usually take about 4 strokes of the hone.

    Reassemble the cylinder heads using new valve seals.

    Please follow this diagnosis process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed. If these steps do not resolve the condition, please contact GM TAC for further diagnostic assistance.

    Anyone know where I can get a copy of this TSB ?

    Also, anyone else had the check engine light come on, indicating (according to the dealer) that the knock sensor is not working properly ?

    RE: 2008 Lucerne CXL

  • scandiakenscandiaken Posts: 11
    Has anybody got a cure for my inability to read the instrument panel on the 2008 Lucerne in the daytime? I cannot believe that Buick has not put out a service bulletin on this problem. Surely there is a fix of some kind. Thanks for your help.
  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 57,602
    Which engine?

    Also that's not the nomenclature that the factory uses for TSBs. That must be some other website's tracking number, like I'm posting for the other member in the next post

    this is the only TSB I found that even comes remotely close to your problem, but it doesn't quite sound like what you are experiencing. There's nothing else I can see on the list unless it's a brand new TSB just out:

    Bulletin No.: 02-06-03-008C

    Date: May 30, 2007

    Low Voltage Display on IP Gauge, Lights Dim at Stop Lights, Battery Discharged, No Start, Slow Cranking, Dim Lights at Idle, Low Generator Output

    1990-2008 Passenger Cars and Light Duty Trucks (including Saturn)
    2003-2008 HUMMER H2, H3
    2005-2008 Saab 9-7X


    This bulletin is being revised to add the 2008 model year. Please discard Corporate Bulletin Number 02-06-03-008B (Section 06 - Engine).

    Any vehicle may have a low voltage display (if equipped with gauges), lights that dim at stop lights, slow cranking, no start, low generator output at idle or dim lights at idle when electrical loads are heavy at idle or under slow driving or infrequent usage conditions. These characteristics may be more noticeable with customer added electrical accessories, or with a discharged battery. These are normal operating characteristics of a vehicle electrical system and no repairs should be attempted unless a proven fault has been diagnosed.

    During normal driving conditions, when engine speed is above 1000 RPM, the generator is designed to do two things:

    Supply the current necessary to operate the vehicle's originally equipped electrical devices (loads).

    Recharge/maintain the battery's state of charge.

    The following factors may affect generator and battery performance:

    Non-usage of the vehicle for extended periods of time. The vehicle's computers, clocks and the like will cause the battery state of charge to drop (For example; 30 days in a parking lot and the vehicle may not start because of a dead battery or a vehicle which is driven only a short distance once a week may end up with a discharged battery to the point where the vehicle may not start). This would be considered abnormal usage of the vehicle and the normally expected result for the vehicle battery, generator and electrical systems.

    At idle, vehicle electrical loads may exceed the low speed current (amperage) output of the generator and when this happens the shortfall comes from the battery. This will result in a drop in the electrical system voltage as the battery delivers the additional electrical current to meet the demand. This is equivalent to the brown outs experienced by homes and businesses when the electrical demand is more than the supply. See Figure 1.

    Extended periods of engine idling, with high electrical loads, may result in a discharged battery. Attempting to recharge a battery by letting the engine run at idle may not be beneficial unless all electrical loads are turned "OFF".

    Increased internal generator temperatures from extended idling can also contribute to lower electrical system voltage. As the generator's internal temperature rises, the generator's output capability is reduced due to increased electrical resistance.

    The table shown are some typical examples of electrical loads.

    Depending on the vehicle application, generator current (amperage) output at engine idle speeds of 600-700 RPM can be as low as 35 percent of the full rated output. With enough electrical loads "ON", it is easy to exceed the generator current (amperage) output when the engine is at an idle of 600-700 RPM. This is a normal condition. The battery supplements for short periods of time. Items that affect the vehicle's electrical system current and voltage at idle are the number of electrical loads being used, including add-on accessories, and extended idle times. When the vehicle speed is above approximately 24 km/h (15 mph), the engine/generator RPM is high enough and the generator current (amperage) output is sufficient to supply the current (amperage) requirements of the vehicle as originally equipped and recharge the battery.

    Dimming lights at idle may be considered normal for two reasons:

    As the engine/generator speed changes, so will the current (amperage) output of the generator. As a vehicle slows, engine/generator RPM slows, and the current (amperage) output of the generator may not be sufficient to supply the loads, the vehicle system voltage will drop and the lights will dim. Dimming of the lights is an indication that current is being pulled from the battery. If the battery is in a low state-of-charge (discharged condition), the driver will notice a more pronounced dimming than a vehicle with a fully charged battery.

    When high current loads (blower, rear defogger, head lamps, cooling fan, heated seats, power seats, electric "AIR" pump, or power windows) are operating or cycled "ON", the generator's voltage regulator can delay the rise in output. This effect, usually at lower engine speeds, can take up to ten seconds to ramp up the generator output. This is done to avoid loading the engine severely. To increase current (amperage) output, additional torque is consumed by the generator. The engine computer (PCM) will ramp up engine/generator speed in small steps so engine speed variations are not noticeable to the driver.

    For diagnosis of the battery and or the generator, refer to the appropriate Service Information or Corporate Bulletin Number 05-06-03-002B.

    Nope. That is not the problem us Lucerne owners are experiencing.

    In our case, there is no light at all on the instrument panel when
    driving without headlights during the day. It is probably
    exacerbated by the fact that the gauges are behind deep cylinders
    so the sun does not light them. When we turn off the engine,
    the lights light up wonderfully! I am quite sure it would be a small
    circuit board fix, if only someone would just develop it or identify
    it as being available.

    At night the dash lights are fine, and the reostat that adjusts them
    works just fine. I think it was just a design oversight.

    Thanks for your attempt to help.

    For a temporary fix could you turn on your parking lights?
  • 0patience0patience Oregon CoastPosts: 1,622
    There is a new high contrast intrument panel for your vehicle.
    If it is still under warranty, the new I/P should be covered.

    See this bulletin:

    Instruments - Difficult to View Cluster in Bright Light
    Bulletin No.: 06-08-49-021A
    Date: December 05, 2006
    Difficult To View Instrument Panel Cluster (IPC) Display When Driving Toward Bright Sunshine (Replace Instrument Panel Cluster)
    2006-2007 Buick Lucerne (U.S. and Export)
    Certain VIN breakpoints (see dealer)
    This bulletin is being revised to update the table of IPC part numbers. Please discard Corporate Bulletin Number 06-08-49-021 (Section 08 - Body & Accessories).
    Some customers may comment that the instrument panel cluster (IPC) display is difficult to see when driving toward bright sunshine.

    This condition may be caused by an insufficient color contrast in the IPC display.

    Technicians are to install a new IPC with a display that has improved color contrast. Refer to the Instrument Cluster Replacement procedure in SI for more information. The original IPC part number may be obtained using a Tech 2(R).
  • scandiakenscandiaken Posts: 11
    That sounds good. I will definitely share that info with my Buick Service Department.

    I am afraid it is too little to correct the problem, however. As far as I can tell there is NO ILLUMINATION on the instrument panel when driving without lights on. Turning the parking lights on halps a little (here is where the contrast could be inproved (I would say the lights should be brighter)). When the parking lights
    are on, the running lights go off. If the running lights are a safety factor, as I was
    led to believe, they should be on when driving.

    Thanks for the information.
