      Re: (12Ounce)

      Somebody with an engineering degree can correct me with the details but I think there is very little time when this engine has negative crankcase pressure, thats what the PCV valve (or equivalent) is for, so the engine can breath from the positive pressures it generates.

      Wow! That is somewhat disappointing. Was the countershaft painted, or have any other protection from moisture?

      Are you done with your repair? Is it working again?

      Re: (cdnx90)

      Internal combustion engines have negative crankcase pressure. The PCV helps to facilitate that by using the vacuum of the engine to help ventilate the crankcase. IF you have worn rings and IF the method (or design) of crankcase ventilation is not sufficient, then you can have positive crankcase pressure created by the combustion chamber pressures leaking by the rings. Positive pressure is bad. Dirty oil, oil blown out of seals and orifices and loss of horsepower are just a few byproducts.

      Finished!!! A lot of hard work, but I turned the key and she fired right up!! No warning messages or engine lights, and all fluids seem to be in their respective places. I have some more pics that I will post soon. Roughly $1200.00 in parts and pieces, tons of labor, and a big smile when I drove it out of the garage!!!

      Re: V8 "CB-Club" Members - V8 counter balance shaft failure thread (safetyfirst)

      Well, I am now part of this Club and didn't know about it till the Screeeech of my engine one random day, otherwise I would have got the higher production model. I love this car and its been great, till now. It runs but CB is the issue and my local Volvo dealer has verified it. I have no Extended warrenty and am Bairly outside of Factory warrenty by a few months my XC is under milege at 48k. I now have to call VCNA and try to start what they call a "Goodwill warrenty claim" to see if the District rep will fix this under war. I will update you with the detail list you have below. My dealer quote for repair is $17k = new motor replacement and since Volvo recomends full replacement I have found it hard to find anyone that will touch the car now.

      Any info you guys can provide would be great as I have heard of an instance that Volvo did do warrenty work on an 2005 with 120k on it.

      Don't continue to drive it! You will turn a large problem into a HUGE problem if you do. Until the chain comes off the camshaft wheels under the front cover ... the engine is repairable at a moderate cost (assuming you do the work yourself, or find a local independent shop to do it for you.)

      Of course, if you can get Volvo to step up ... that's great! But if not, I would recommend you print out all the photos "ione2retire" posted (showing the bearing failure in great detail) and make trips to local auto machine shops and have discussions with them about the problem. They will surely know some client of theirs that will do the work for you reasonalbly. (If you weren't all the way across the country, I would do it for approx. $3k ... that is, if the wife would let me!)

      Re: V8 "CB-Club" Members - V8 counter balance shaft failure thread (12Ounce)

      12Ounce .Thanks for the reply. And suggestion. I did just that and did not drive any further. The car is sitting at the dealer now awaiting VCNA reply to my "Goodwill Warrenty" request to see if they will honor there car. Better news than before as well the issue has been caught early since I knew the minor noise (when I first heard it was absolutely not normal and was concearned of further damage) turned into a horrible noise the first start up at Volvo. So the Better news = they can and will repair the CB issue for 4200 or so, much better than the 17k for full replacement. Thanks for the repair offer I had considered doing it myself as well if I couldnt find a shop to do the repair.

      Thanks

      Anyone else with suggestions would be great since I have to deal with the "so close to warrenty issue" of having Volvo help with repair.

      2005.XC90.V8,

      Can you clarify your engine number?

      What does 44XX mean?

      I assume $4200 is for CB bearing fix and not new engine.

      Be sure they drill the drain hole.

      $4200 is better than $17,000, but I still think a recall is warranted.

      If this was a Toyota problem, this would be a free fix.

      Good luck, keep us posted please.

      Do not run it any more, either tow it or push it. The next start could break the cam chain and then
      it will be a 17k fix. Disconnect the battery to make sure.

      Get ahold of Addy49er https://forums.swedespeed.com/z...age=3 and ask to take a look at the letter he sent. I'd do the same and compile some info from here to send along with it if they start to balk. At 48k miles, this is absurd. If they still resist, maybe get a strong worded letter from your favorite attorney and submit another letter.

      Had mine fixed at 120K miles at a cost of $100. Just worked with the general manager at the dealership and they took care of us. Start with him. Our repair totaled roughly $6K.

      Thanks for the info guys the Volvo area rep got back and wants my service records. so Im on step 2 i guess of this process hopefully they will honor there good name (since thats why I purchased Volvo). And I got some Heico Volution V (20's) that I got shortly before this issue and am dying to put them on.

      I will cont with updates as this goes all these post;s have made the difference.

      Thanks

      Sorry to hear about your engine troubles! Do not let volvo get away without covering this in full. This is clearly a design flaw,and they know it. That is the reason for tech bulletin and mid production change to include drain hole in the block. I had no prior knowledge of this issue or even this forum until that dreadful squeal emerged from under my hood. If I did, I would have had my vehicle towed to a volvo dealer ( at their expense) and insisted that they repair it under some form of warranty. Maintenance has no "bearing" on this rear bearing. It is external and allowed to wallow in the slop of the engine compartment until it eventually fails.
      You are doing the right thing. Use the "ammunition" from this site. Show the volvo rep my pictures. Let them know that you know they made a mistake, and they need to be responsible. This isn't a Yugo, it's a volvo!

      Which I find is technically unecessary except for them to find a way out. It's a sealed bearing and 0 or 100 oil changes wouldn't matter a bit....

      Re: V8 "CB-Club" Members - V8 counter balance shaft failure thread (fredrok)

      Well here is Volvo's answere....... we will cover all but 1000. so that means the job to me was about 4300 now will be 1000 . the cost they will actually pay is 1600 due to the fact they want dealer to do the warranty under warranty cost which turns out to be 2600 total. so all in all the parts are gettiing fixed and I save 3300 in the end. this seems fair to a point but they really should pay the whole bill. i just need my car back fixed so i will pay the 1k out of pocket. I will be writing a letter and saving my reciept's in case of a recall in the future.

      Thanks for all your input and will keep you all updated will the repair process.

      I was at my dealer last week and saw a black XC90 V8 either a 05 or 06 with the engine dropped out. i asked my SA about it he said an internal shaft failure. He wasnt very happy that i asked or that i asked to look at the engine. I dont know how many miles were on it.

      Re: V8 "CB-Club" Members - V8 counter balance shaft failure thread (2005.XC90.V8)

      Do you mind if I ask at what level the decision was made to cover part of the cost? My CB Shaft bearing failed in November '09 after just 55,000 miles and 5 months out of warrenty. I've tried to get some help through Volvo Canada and they shut the door on me. Could use a little extra info to support my case. Any help would be appreciated.

      Re: V8 "CB-Club" Members - V8 counter balance shaft failure thread (mitter)

      Mitter

      I called VCNA and started a "Goodwill warranty" claim. They email the area rep the info and get ahold of the Volvo dealer your car is located at. I took my dealer the service records i had and a print out of a couple of these post (about 15 pages + ) then the area rep contacted the dealer and set up an inspection. They came back with the offer of covering the work and 1k is all I pay. I am the second owner and purchased the xc90 while it was still under warranty. Another member wrote a letter to the President and was further out of warranty then the both of us so the covered the cost (about 6k in work). I need my car fixed now but i will be writing a letter as well. I caught the issue early before the bearing broke so all that is needed is to replace the parts and anything minimal that may be damaged.

      Did your bearing break during use and a new motor is needed? or did you catch it early and just need shaft and bearing replaced?

      Re: V8 "CB-Club" Members - V8 counter balance shaft failure thread (2005.XC90.V8)

      Thanks 2005.XC90V8,

      Volvo of Canada Customer Service informed me that I was out of warranty and therefore did not qualify for Goodwill. I think it was because I bought a US vehicle and was dealing with Volvo of Canada. Either way they rejected my request to cover the repair work and closed the case, stating that once a case was closed it could not be re-opened. I decided to write a letter directly to Doug Speck, the President of Volvo Cars of North America. Mailed it out today, so hopefully, I'll receive a positive response. I'll make sure to post any updates. As for the damage done to my vechicle, my wife pulled over as soon as she heard a banging noise coming from the engine. I had the vehicle towed to the dealership and they were able to replace the bearing and shaft. They said there was no damage to the engine itself so I was lucky there. Total repair bill was just over $5,000 (volvo didn't charge me for drilling a weeping hole prior to putting my engine back together). I had to pay the bill because I needed my vehicle back prior to getting this issue resolved. Now I'm left hoping that Volvo will show me some goodwill. In fairness to my dealer, their service has been great. As mentioned above, I bought my vehicle out of the States so this is a new relationship I'm building with this Canadian dealership. Needless to say, this will be my first and LAST Volvo if somebody doesn't step up to the plate. A big thanks to everyone who has posted to this site. Without this information I doubt I would have continued my fight beyond the Volvo Customer Service level.

      Re: V8 "CB-Club" Members - V8 counter balance shaft failure thread (mitter)

      Well I promised an update on my situation. My CB Shaft bearing failed in November '09 at 55,000 miles (5 months out of warranty). Since this time I have been trying to get Volvo to cover my $5,000 repair bill. I wrote a letter to Mr. Doug Speck, CEO of Volvo Cars of North America describing my situation and the information I gathered from Swedespeed. The response received from Volvo's Executive Management Specialist was, and I quote, "We have reviewed the history of your vehicle and understand that you are dissatisfied with the need for certain repairs, but your vehicle is outside of warranty guidlines and no further warranty coverage will be offered. Also, we have verified that no recall exists in regard to the part that has failed in your XC90....."

      The letter continues on to say, "please know that Volvo Cars of North America performs their own research regarding quality assurance and part failure and in no way finds internet claims as an accountable measure of product quality"

      The letter ends as follows, "Although we do value you as a member of the Volvo family, regrettably, we are not in a position to accommodate your request or consider this matter further."

      Folks, I need a little help here. I'm not ready to let go of this matter and could certainly use some concrete information from those who have had their repair costs covered by Volvo NA, not their dealers. Obviously, internet claims are useless. It's a lot to ask, but if anyone can provide private info it would be of great help, I believe my email address should be listed in my Swedespeed profile if you are uncomfortable with posting.

      I get a good laugh out of Volvo hiding behind the fact that there is no recall. It's not difficult math to calculate what the cost to Volvo would be if they had to bring every 2005 XC90 with a V8 engine (predating engine #6833), in to have a weeping hole drilled and possible replacement of bearings. My dealer billed me $2,184 in parts and 2,430 in labour. I'm figuring it would be an expensive recall and Volvo is going to avoid this issue like the plague!

      Why dont they just add a gasket and keep the darn water out!

      I'm sure Volvo wishes they had taken a closer look at this design in the beginning. You are right, if this area had been treated as part of the crankcase ... complete with oil, etc ... instead of "outside the engine", the results would have been much happier. Of course, the bearings would have been slightly different in design, but would perhaps been a "wash" in initial manufacturing costs.

      Being an owner of a 07 V8 Sport, I'm curious, it sounds like this problem ended mid year 05, is that correct, or should I now be sitting on pins and needles as well?

      You are okay, the 05's and some early 06's are affected. Some one had posted a VIN# range for the affected engines on another post. Just do not wash the engine or engine bay at all.

      You are "aware", and that is good. If you intend to keep this vehicle a long time, or intend to put high miles on it, I would recommend getting an audio recording, or just a simple stethoscope sounding, of the area around the rear countershaft bearing. This would be used as a base-line for later comparative readings. Would just make good maintenance sense to me...even though you shouldn't expect trouble to be as likely as on earlier models.

This would be used as a base-line for later comparative readings. Would just make good maintenance sense to me...even though you shouldn't expect trouble to be as likely as on earlier models.
      Interesting, I think I'll do that.

      Thankfully this is certified, so I still have some years/miles to go on it and so far it's been rock solid all around.

      Thanks.

      The engine number is located on a white label on the left side of the engine (as viewed from the hood) case. The label doesn't say "engine number", but rather references the part number and, if I'm remembering correctly, a serial number. I think the affected engines ended in the 6,xxx range (I don't remember the exact number, 6333?)
