    Thanks for the reply.  Interesting.  I had not heard that.  We actually have the T6.  As of this writing, the problem seems resolved.  Volvo (WA) replaced the oil cooler, flushed system but oil still there.  They told us to drive it back to Volvo (CA) and have them look at it since the problem originated when we had our 67,500 service which included a water pump replacement.  Bottom-line each service dealer was suspect of each other's work.  Volvo (CA) cleaned out system again and the oil disappeared.  They then  asked us to drive it for another two weeks to see if problem re-occurred, it did not.  However, they had us come back in to replace all the hoses since they were now contaminated with oil from all the driving around we did.  FYI, at no time during this event did our oil level go down nor did the water coolant appear in the engine casing or transmission.  It almost seems as if someone put oil in our coolant reservoir, but we know that cannot happen, right?!   End of the day, this exercise in Volvo maintenance has cost us over $7k, plus a ruined family vacation, but we now have one heck of mystery story.

You didn't specify which motor you have. I heard that there was a recall on the 4.4L V8, where oil mixes with coolant in the oil cooler.

1994 Mazda B3000 V6 engine oil pushes into coolant. Have to add engine oil all the time and drain the recovery bottle. 65,000 miles. Never been overheated.


Failure of head gasket between cylinder head and block.

Because oil pressure is higher than coolant pressure, oil will creep across poor sealing area of head gasket from the oil riser drilling that feeds the cylinder heads cam assembly's.

Worst case scenario would be a cracked cylinder head/s. No totally unheard of but rare.

Continued oiling of the coolant system will rot out the coolant hoses from the inside to the point they will burst.

Due to the year of this engine it may be prudent to find a used engine with less miles and swap it out.

Is there a way to grease the suspention or draive shafts of my xc90?



Complaint Number: 10363820 Incident Date: October 24, 2010 Date Added to File: November 3, 2010 Description of the Complaint:October 10, 2010 purchased cash 2005 xc90 v8. Went through safety and emission service for registration-- okay. October 22 heard a strange noise from engine, called volvo dealership to request service. Didn't drive on october 23, 2010. On sunday, october 24, went out to move the car for opposite side parking and to gas up for drive to service center. Car stopped at service station, and had to be towed to dealership. Dealership diagnostics october 25, 2010 confirmed: noise is from either broken connecting rod or balance shaft....Advice to customer "needs engine" at a cost of $14,000+. The car did not come with a Warranty and even now the dealer is becoming increasingly evasive--as he says he was the owner/dealer at the time of sale, and as individual seller registered in another state and not new york, so does not have to honor Warranty or assume responsibility. Call volvo north america on october 26, 2010 with no knowledge of our ownership, (still havent received title to car). Response was --no Warranty no assistance with this counter balance or any other issue beyond 4 year/50,000 miles. Concern: before purchase when asking the dealer no mention nor when researched no revelation of the counterbalance shaft being an ongoing issue for the 2005 xc90 v8. However, further evidence clearly shows design flaws in the original yamaha engines, and a slight covert attempt by volvo to fix it via its limited edition technical service bulletin(TSB) to drill the hole in the shaft to let build up moisture escape. Additionally, volvo's second attempt to slightly address the counter balance issue is evidenced via its limited and pay-to-get TSB informing dealerships not consumers of not washing the engine, which may lead to moisture build up and total engine failure. Our attempts are now being made for volvo to maintain its slogan of "safety for life." we want the safety attribute to be effective and useful when the car is operable, and not when the car is inoperable.



2 Complaint Number: 10343465 Incident Date: June 16, 2010 Date Added to File: July 15, 2010 Description of the Complaint:Volvo xc90 2005 v8 - counter balance shaft failure leading to total engine failure and requiring engine replacement 3 Complaint Number: 10324165 Incident Date: November 16, 2009 Date Added to File: April 7, 2010 Description of the Complaint:Counter balance bearing failed at 55,504 miles. Non-greased bearing failure, caused by rusting, due to moisture build up inside of engine chamber. Vehicle had all required service done a volvo dealerships. Engine was repaired not replaced, for a cost of $5000.00. Repair work was done at volvo dealership. Volvo mechanic drilled weeping hole in chamber where counter balance shaft sits to allow water caused by moisture build up to escape. Drilling weeping hole was part of a tech bulletin issued by volvo. V8 engines for the xc90 produced in 2005 did not initially have this weeping hole in them. This design change was implemented part way through the production year (I believe post engine #6833). Letter was written to the ceo of volvo cars of n.A. Llc and representative from his office refused to provide any support, stating that the vehicle in question was out of Warranty and that there were no recalls with regards to this issue. Info provided to volvo from swedespeed.Com (see ODI id #10313311), however, this was rejected by volvo as a non-valid source of information (their own customers!). The repair job to replace the cb shaft and bearing was over 30 hours, not to mention the parts cost. What will it take volvo to admit there is a problem here and issue a recall to replace bearings and drill weeping holes in their 2005 xc90's with v8 engines? considering the cost they will incur, I'd suggest they will need to be pushed. The cost of engine repair is ($5,000) and engine replacement ($15,000+). All bearing failures outside of Warranty are falling on the shoulders of the consumer. Recalls are about safety not cost to the manufacture. Just because this problem may only be linked to the 2005 v8 engines doesn't mean it is not important enough to be addressed for not only consumer financial protection but also for safety reasons. Thankfully my engine didn't fail while my family was driving on a busy interstate!



4 Complaint Number: 10313311 Incident Date: February 13, 2010 Date Added to File: February 23, 2010 Description of the Complaint:Ungreased bearing failing on 2005 v8 volvo xc90 a balance shaft bearing is failing due to the fact that the bearing is not greased and water can enter into the bearing cavity and make it rust. Once this happens, it can produce a total engine failure, and besides the fact the engine is totally compromised and needs replacement, it would obviously impair the ability to drive the vehicle, especially at highway speeds. This particular car has an engine with only 60k miles, serviced regularly and with the last major service performed at a volvo dealer at about 50k miles. The car has been driven very lightly and it only has made about 10k miles in about two years. Here is in summary what I found about this: -the bearing that is failing is not lubricated (so nothing to do with oil in this case), and it fails due to the fact that water and/or humidity gets to it, by washing the engine(?) never did that anyway - or by the car just sitting in a lot.. -there is a volvo bulletin that details what needs to be done, including drilling a weeping hole into the engine block to drain water; this shows that the problem is acknowledged and a fix has been put into place; it also shows that there is significant number of vehicles out there that have the same issue. -this seems to be a very common problem with this type of engine and year (2005 xc90, v8 engine, engine series less than #6800) I have pointed out a few threads below that mention the same issue. Given all the reasons enumerated above, I am asking for an evaluation of this issue and I really feel volvo should recognize this as a design problem, issue a recall and step up to fix this

My car was running great. i ran over something off road that made the exaust leak near the motor. i continued to drive it . then it began to run low in water and if i didnt keep a close eye on it, it would...


Exhaust and coolant problems are two separate things. It's possible the donut that connects your exhaust manifold to the pipe came loose or the exhaust manifold or pipe has a hole from rust. You obviously still have a coolant leak somewhere. Start the engine and look under the car to see if you can see coolant dripping. It's either coming from one of your hoses, thermostat, water pump or coolant lines that run from your radiator to your transmission (if you have an automatic). There's a good chances are if it's still leaking the new water pump may not have been installed correctly. Also check your oil to make sure it's not milky white. That means your oil is mixing with the coolant from a blown head gasket. That can happen if the engine overheats severely. Head gasket repair is very expensive.

Water Pump Leaking??


yes it is a very expensive repair, they (whom ever they are) may have seen a coolant stain on the area around below the pump under the car, if it goes it can overheat and cause serious engine damage very quickly. have u been under the car to look?

Slow to rapid coolant rise after engine is shut off


Normal. This is called heat soak. When you stop the engine, its temperature rises since the coolant is no longer being circulated by the water pump through the radiator. The coolant then expands and goes higher in the overflow tank. As the engine cools, it retreats back into the engine. Proper level should be determined only when the engine is cool.
