      V8 serial number

      I believe the last engine number before the weep hole mod is #6833, I have a 05 V8 in the low 3000's, 82k miles, no -problem so far, keeping her dry! with my fingers crossed. As someone else mentioned I think I'll buy an engine stethoscope and listen to the sound of the "healthy bearing" and give it a listen with each oil change and see if I detect any changes, if they had just made that bearing with a grease fitting on the journal it could be greased every oil change and probably last forever!

      Sadly I have been through a pretty rough year with my '05 XC90 V8. First the counter-balance shaft failure mentioned above ($6000)and now the valve body/transmission failure ($7000). Would like to hear from any other unfortunate souls who've suffered through this.
      I have a lawyer and am now compiling info regarding both of these well known(to Volvo)issues. There is a Volvo tech advisory about the counter-balance shaft issue that I would sure like to get my hands on. Any disgruntled Volvo employees out there? Has anyone else pursued legal action on these known design flaws? I'm out almost $15,000 what do I have to lose? We've driven Volvos since the 70's and have never experienced anything remotely close to this. If Volvo doesn't step up to the plate on this we will never drive another one. Thanks for your time.

      You can get the tech net notes from www.volvotechinfo.com for $6.00 IIRC or other places on the internet as well.

      Hey...I picked up my XC90 at the dealer here in Saskatoon today. The total bill for a software upgrade(which didn't help)and a valve body replacement(which didn't fix the transmission shuddering)ultimately requiring a complete transmission came out to just under $13,000. I've found bulletins pertaining to this common transmission problem (on '05s). In one bulletin there is a note identifying transmissions starting with serial number 06J and later that already have the latest valve body which was designed to prevent the shuddering. This known design flaw is no different than the counterbalance shaft bearing that they were also aware of. I'm not sure if your dealer charged you a $500 inspection/certification fee when you inported your XC90 but I was told that they wouldn't touch it if I didn't pay the $500. After the certification they told me that all recalls had been done and that everything checked out. It's at that point where Volvo Canada is compelled under what is called "implied contract" they took my $500 for a certification and did not comply with the contract by advising me of the known design flaws with the '05 XC90 V8.

      So this sad saga continues (total so far over $20,000) but rest assured I will not stop till I'm compensated.
      I also have an ace in the hole, a friend of mine works for CBC and I've told him this story and if things don't go my way they could find themselves getting some very negative press(a' la Toyota). So stay tuned, thanks again for your note.

      I am officially scared........i just bought an 2005 XC90 V8 from a dealer with 82000miles.

      I am getting a strange sound when im crusing above 35mph and i apply on a small amount of gas so the car very slowly accelerates. Its a knocking/tapping sound. Its not loud and can only be heard at speeds abovr 35mph when the car is barely accelerating. At idel there is no sound, if i free rev the car there is no sound and if i accelerate more rapidly adn the car chnages down a gear or two then no sound is heard.

      Any ideas? Praying this isnt the CB. How can i check to see if my car has ever had the problem or if its had the hole drilled?

      Thanks,

      I cant hear a noise similar to what is being described, even with the hood open.

      the last four digits of my vin start with a 3 so im assuming i fall into the dreaded CB failure category.

      Can a mechanic tell if anything relating to the CB has been done in the past?

      Open hood...go to the passenger side with bright flashlight...look for Engine serial number...its down
      there on a white tag(may have to push some hoses outta the way...you will see with a bright light.

      CORRECT! "engine serial #4099" welcome to the CB-CLUB. I am engine serial # 5441.

      I am no mechanic...BUT IF your CB bearing goes...your engine will sound like the following similes:
      1. a Ford Model T ("tin Lizzy") engine
      2. someone threw ball bearings into your engine.
      3. shaking a "box of rocks"

      You may not have the CB bearing issue...because it is an unmistakable (awful) noise emanating from your enginer.

      Please get to your local Volvo service tech to have your particular situtation resolved...

      Car is at the local euro specialist workshop. I told them about my concerns and they're looking into it.

      Is it worth getting the fix for the bearing put in place before the bearing fails? Or is it too late?

      It is a mega-thousand $$$$ job, and Volvo typically, covers the labor when it fails...

      Relax, and wait for the failure...you will not miss the initial sound...the sound of the freezing bearing is rather distinguishable...and it might never happen...so far rather small %% of bearings failed - my estimate is less than 10% - un-scientific scouting of Internet...there were about 6500 engines of questionable design...and I seriously doubt that 650 engines failed...

      The odds are on our side...

      ok so the problem has nothing to do the CB but the mechanic cant figure out what the problem is. im going to post another thread about the sound im hearing to see if anyone else has had the problem.

      New Member to CB-Club, though I haven't been baptized yet. Engine SN 5133, 81k miles, but sounding good so far. I bought the vehicle used and found that the transmission was replaced/reworked by Superior volvo -KC at 60k miles, so hopefully that will have resolved any issues with that.
      With regard to the CB failure, have some of you caught it just before catastrophic failure and had it replaced? Did or would this save any money? I have tried to find some good pics of the problem, but they are never very clear. Is the bearing in question only on the one end? What has been the situation with the other end of the shaft? I am surprised that the bearing can't be changed without pulling the engine (prior to complete failure). Has anyone tried this?

      Actually, most folks (at least according to the posts here) caught the problem before the catastrophic consequences, so only the bearings and/or shaft should be replaced. The replacement does not require pulling the engine, only removal of one of heads. My INDY mechanic did one engine a couple of years ago..the biggest obstacle, according to him, was to pry the head from under the little horizontal panel in-front of the windshield...

      I am rapidly reaching the 100K (98+)...so far so good...runs like a champ...

      As I interpret the drawings I have seen of the engine ... the front bearing is sealed only on one side (the rear side) and is open to the front area of the engine that includes the chains and chain-wheels ... plenty of engine oil splashing about ... so the front bearing should last "forever". However, the rear bearing is sealed on both sides and pre-filled with lubricant. As the bearing warms up during normal service, the lubricant expands and attempts to escape .... as the bearing later cools and the lubricant contracts, if the seal leaks, outside air or moisture may be drawn in. It becomes very important to keep water from pooling against the bearing seals. Eventually the bearing will fail anyway.

      Thumbs down Engine 4166 failed.

      Model year - 2005.5
      Chassis number -
      Delivery date -
      Age at Failure - 6 years
      Mileage at failure - 56,202 miles
      Engine number (if known) - 4166
      Average driving history - e.g. Mostly suburban, not dusty.
      Environmental conditions and approx % time in each - e.g. dry 55%; wet 10%; snow or ice 35%.
      Washed engine ? - May have been washed while on dealer lot.
      Repair action - Awaiting CB shaft bearing replacement (slowly in my garage)
      Time to Repair - 4 weekends and counting (in my garage at home, no lift, moderate hand tools)
      Repaired under - doing repair myself. Aftermarket warranty wants all oil receipts, don't have them.
      Repair cost - Under $1,000 for additional tools and parts (bearings, seals). My own labor is free.
      Cost to You - See above.
      Name of Dealership - SESI Lincoln Volvo
      Supportive Dealer ? - Nice people but wanted to charge $3,000 to properly diagnose. Warned about aftermarket warranty wanting oil change receipts, which was helpful. Charged $100 to determine it wasn't the accessories making noises.
      Supportive VCNA ? - Didn't try. Didn't want to incur additional downtime waiting to be told they won't help.
      Other comments - Stupid engine design. Also, VIDA is not very detailed in repair procedure and contained wrong information (bolt locations on lower intake) - AllData is better but still not at General Motor's (Helms) service manual level of detail. Does not require engine to be dropped out or even removed so this repair can definitely be done at home with enough time and handtools. I will post procedures outline and tips, and some photos (and images from VIDA where helpful) when I'm done.

      Query Re Engine Number

      Hello all, new member from Oz. I have just purchased an XC90, first Volvo. I have read this thread with some concern. I have a 2007 XC90 V8 with 85000km's (first registered in Australia in 08/2007 but "built date" is 11/2006). Even though I understand that the effected engines seem to be those built in 2005 and maybe early 2006, my engine number is "2000407". What I am hoping is that the engine numbers you talk about in this thread relate to the North American/Canadian market and we have our own series of engine numbers here in Oz. Can anybody pls confirm this for me because if it isn't the case I'm wondering how I have such a low engine number in a vehicle built in Nov of 2006 not to mention the fact that I would then also be in line for a potential CB failure. And if I can also work out why I have a continual battery drain..............Not a promising start.

      Regards Barney

      Looks like I'm the newest member to the CB club. Bought a super clean 05 V8 with 63k miles at Volvo of Oak Park (chcgo). They told me the car had gone through their 200 point inspection but within a week and a half the engine began to knock after the car warms up. Took it back and sure enough - balance shaft failure. Thankfully I paid $3,000 for the extended powertrain warranty. Since the repair was so expensive an "inspector" had to come and look at the engine once it was torn down. Now the warranty company has designated it a "long term failure" rather than a "catastrophic failure" and claim that it is not covered by the warranty because the balance shaft is not lubricated by engine oil and is thus excluded from the power train coverage. The harmonic balancer is covered and the "balancer shaft belt" is covered (even thought this engine does not have one). The dealer has never heard of this problem (!) and of course they "never would have sold a car with this condition" but as of now it's been over two weeks and the car is sitting there disassembled and I'm waiting for either the general manager or the warranty company to blink. Does anyone know of a tech service bulletin? I can't imagine one if the highest volume Volvo dealers in the country would not be aware of this issue. I need to gather as much info as possible before I call my attorney. I don't know what recourse I have but to lawyer up and put pressure on the dealer to put pressure on the warranty co. I'd imagine the car is too old to warrant contacting Volvo of North America? Anyone gone through a similar ordeal? Sigh.

      Call and write to the Volvo of NA. It is a known issue, and, typically, Volvo will cover the labor and, maybe, some parts...

      Start there...most failures did happen after the warranty has expired...your case is rather common...read this thread backward...there were several people people in your shoes here, who successfully recovered most of the cost from VCNA.

      Sorry you have had such bad luck. Let us know how it turns out with Volvo.

      What strange and creative "legalese" warranty companies come up with to avoid their commitments. Hope they gave you this crap written down. What jerks! So anything not lubricated by engine oil is excluded from the power train! Wow! Well, how about the transmission ... its not lubricated with engine oil. The drive shafts??.... not lubricated by engine oil, but "prelubed"with grease, just like the engine bearing that has failed. Funny they should suggest "harmonic balancer" (I don't know if this engine has one ... probably does) usually found mounted on the crankshaft end ... and usually is part of the crankshaft pulley that drives the auxiliary serpertine belt: anyway.... its not lubricated at all!

      Update #1: Finally got a call from the general manager of the dealership. He is currently working with their Volvo rep to "find a solution." The warranty is carried by Apco (Automobile Protection Company). They continue to hide behind the fine print in their contract. Even though it covers the harmonic balancer, timing chains, all gears, guides, and guards they are hiding behind the fact that the counter balance shaft isn't lubricated by engine oil...but isn't the bearing on the back side of the engine? Either way, it's clearly connected to the timing chains and gears and performs the same function as the harmonic balancer so I really think the dealership should saddle up and flex their buying power muscles with the warranty company and make them honor their commitment. I picked up my copy of the contract out of the glove box today and realized there's a binding arbitration clause in there...they've got it all figured out. The dealership is trying to get Volvo to kick in and cover the fix rather than the warranty company - I've made it abundantly clear that I'm not paying a red cent beyond the dectible. I should hear something tomorrow morning regarding Volvo's contribution. I bought an alldata subscription but it doesn't have the technical service bulletin for this repair. There is a page from a service manual instructing an 8mm hole to be drilled below the bearing if there isn't one. That's the closest documentation I can find to Volvo admitting culpability. Does anyone have access to the actual tsb for this phenomenon? I need to get as much documentation to the dealer as possible. The manager keeps feigning ignorance to the whole problem and says they have only sold fifty or so V8 XC90s and have never seen this failure! In almost the same breath that he says they are the largest dealer in the Midwest and one of the top dealers in the country! We all know he knows what's going on but he's put the onus on me to prove the case.
      Thanks all!

      Both do their part to make engines run more smoothly. Like I wrote, the harmonic damper is mounted on the crankshaft ... and can be thought of as a large mass that is mounted in rubber. The rubber acts as a spring and a dampner. Counter balance ( or balance) shafts (there can be more than one ... your V8 only has one) are parallel to the crankshaft, usually turn at a different speed, may even turn in a different direction:

      Update #2: I've searched high and low and can't find any trace of the "balance shaft bearing technical service bulletin." Best I could do was come up with an excerpt from a shop manual on alldatadiy.com specifying an 8mm hole be drilled on all vehicles with an engine serial # AFTER #6833. I can post a PDF if it helps anyone. I didn't actually contact VCNA but forced the dealer to do so. I explained (truthfully) that this XC90 was my fifth Volvo and that irrespective of what happens with this car I'm most disappointed in Volvo's failure to own this engineering mistake and issue an actual recall and how they handle this situation wil determine if there's a Volvo #6. I got a call back from the service manager today and they agreed to fix the car at no additional cost beyond my deductible. I don't know if VCNA is picking up the entire tab or if Volvo Oak Park is kicking in and frankly I was too releived to even ask. Keep in mind we caught the problem before the motor seized so it's only a $5k repair instead of a $15k repair. Hats off to Volvo Oak Park. I'm sure had I bought this car used from a non Volvo dealer and purchased the aftermarket warranty I'd be s.o.l.
