Hello guys,

We have many stelvio's owners in France who have problems with the camshafts, around 15000 or 20000km...
it seems due to the oil of our engines, that have no more ZDDP additives, in order to be "green"... :angry:

Do you have similar troubles ?


thanks :)
 
Hmmm, I guess Sergio will reply, but AFAIK he has been putting additives to his oils from the beginning, and still has had the cam problem...
 
What year Stelvio's and has the Cam recall been done and if so has the oil pump been changed and the engine flushed.

In the US there has been very little of the issue you are referencing and on most of the very early 8V motors, Most of them early 8V's were preemptively retrofitted with the new top end parts and with the latest ones unlike a lot of the problems we heard of from GB where a failure was refitted with the original parts and not the updated ones.

I have yet to hear of a 2010 or 2011 8V motor fail let alone multiple failures in the US.

Pete Roper the premier (AFAIAC) Guzzi wrench in OZ has yet to have a failed 8V that he has serviced.

Has the recommended oil 10W60 full synthetic oil been faithfully used ?
 
There is a thread titled '8V failure info'. It's a long read.

While I don't doubt that failures are still occuring, even on bikes that have been serviced and repaired by reputable dealers I for one am still completely flummoxed by it as I simply can't get an 8V to break!!!! Believe me, I've tried with my own G8!!!!!!!

Pete
 
OK thank's a lot, I'll go and read the post.

see you in 5000km... ;)
 
Hi fellows been gone for a while..........but I just received my MGNOC News Letter and there ia a copy of a letter that was written by someone within Great Britian MG Club to Moto Guzzi Corp. complaining about all the 8V motor failures. All the bikes were serviced by dealers except for one.

As some of you may know I had 2 sets of cams installed in my Stelvio. The last set was installed just before the VA State Rally last year at 28K miles. Guzzi did cover this under warranty.

After putting another 4K miles on the bike the "noise" surfaced again. I pulled the valve train apart and the new cams and tappets were showing unusaul wear again, my dealer had closed their doors so I replaced the tappets (purchased them on ebay) and traded the bike in on a 2011 BMW GSA.

While the BMW is nice, the suspension is fantastic, I miss the torque from the Guzzi motor and it's rev happy throttle response. I was sure hoping that I had purchased a lemon but it doesn't sound that way.
 
:cry: Well the mod was supposed to be done when I bought the machine new in March 2009. 6000miles later the cams had gone and were replaced under warranty. At 18000 miles the cams have gone again. The machine has been dealer serviced and the good news I heard today that Guzzi are going to repair the machine under warranty. Looking on the bright side this set of cams lasted double the last. Am afraid the Guzzi has to go despite the fact that I love riding it. It was a toss up between a new Stelvio and a new Triumph. All happened the week before I finalised a deal. Guess what I'm having next???
 
Fair enough. I understand being to the point where you are done, I owned a Buell.
But the odd thing about your situation compared to the Buell is that the Buells all tended to have the same issues whereas the Guzzi's don't. They did have the issue issue with cams and tappets but once that is properly fixed they tend to work fine, at least here in the US and in Oz. One other advantage to the Guzzi (and at the time to the Buell) is that as much as people like to complain about the company (Guzzi) they tend to be much better in my experience about warranty work and honoring warranties even beyond the expiration date. Not sure you would get the same or better treatment from one of the larger companies.
The new Triumphs are nice. My brother had one, great bike just did not have enough soul to warrant sticking around with him (he is a hard guy to please).
Hope you enjoy your next ride.
 
Hi Folks
I have just received the april/ may edition of Gambalunga the Moto Guzzi Club GB magazine and in it are the results of a survey the MGCGB carried out after receiving complaints about poor reliability on the 8 valve motors from members and the subsequent letter to Piaggio /Moto Guzzi UK and Italy and the reply from Piaggio 's UK General Manager Tony Campbell.
I will not reproduce the complete letter here but under the heading Premature Camshaft Wear/Failure they state
''We are fully aware of the the issues regarding the premature cam shaft wear rates and for this reason the company has been working very hard to source alternative materials in order to fully address this problem. As a result of this hard work Piaggio Group are satisfied that the components being supplied under warranty are of satisfactory quality and as a result will deliver mileage/use nornally associated with this type of component. As a result Piaggio have agreed to extend warrantys for customers that have suffered premature failure to camshafts''.

Just nice to know that we have it in writing from Piaggio that there is / has been a materials problem with the camshafts/ followers and that the problem is in manufacture not servicing ,oil pumps or oils used, though that is not to say that the addition of friction reducers my not help alleviate a manfacturing issue.

Regards Keith
 
Hi, I've just received the magazine as well (probably the last one as I'm giving up my membership) and was quite surprised by the results of the survey. I don't quite know how the survey was conducted but there must be a number out there like myself who weren't contacted and had the same problems as I have described above in my previous posting. I see that they quote several with cams done for the second time (or perhaps it's the third inmy case), just like mine. Obviously with such a problem Guzzi had no choice other than to repair mine free of charge but the whole thing makes no business sense at all. I really loved riding my Stelvio and only used it for high days and holidays - it spent most of it's time parked up in the garage whilst I was out on my working bike that has only done 12000 miles in the last 12 months with no probs other than routine maintenance. I couldn't buy another one because I wouldn't have had any confidence in it at all. As I have said it was my original intention to replace it with the later model with the bigger tank and I'm quite sad about the whole thing. How many others have changed marque to something more reliable (I hope!!)?? - it won't be any worse I sure!!
 
I can understand your disappointment, but don't forget super dooper BMW are having all sorts of problems with the final drives and fuel pump controllers on the 1200's according to what I've read on UKGSer.
The later model with the larger fuel tank has different cam followers to those fitted to the earlier models, so I hope this issue is over for me. This fault for some reason appears to be more common in europe than the USA or elsewhere apparently. I just hope Moto Guzzi will extend warranties for this problem. I suppose I'll have to have my bike dealer serviced once out of the normal two year warranty in the hope Guzzi will do the necessary should the worse happen.
How easy is it to replace the cam followers for the average home mechanic? Does anyone know what the parts cost?

Problem is if the old cam followers were worn down and NOTHING was done to address the oil pump and flushing the engine completely then there still will be a problem even with the upgraded parts. We here in the US where the problem has been "ALMOST" non existent save for a few of the early 8V's and I have heard of only one repeat failure have been led to believe that some of the multiple failures in the UK, France and Spain were addressed without the upgraded parts and some where the oil pump issue was not addressed at all. Yes the buck stops ultimately at Piaggio.After 4000 miles on my 2011 Griso SE the valves after checking twice did not even require a tweak and it is my belief that the factory recommended oil plays a BIG role in engine longevity.
