Yeah, I guess I was thinking of the GranSport.
So does this mean every granturismo engine (4.2 or 4.7) before the variator fix had a 1 in 3 chance of having death rattle occur? Since they are all wet sump engines? Or are the 4.2 wet sumps the 1 in 20 chance and the 4.7 wet sumps 1 in 3. I'm looking at a 08 GT 4.2 atm with the blue valve covers.

I have no idea where those numbers come from...Earlier wet sump cars can develop that issue...It can be a 4.2 or a 4.7...The 4.2 is more common so you see it most on the blue cam covered cars than the red, but the parts are the same....Not all cars have this issue and we have a ton that run fine with no noise...The internet makes every problem for every car seem like all cars have that issue...You are only hearing about the broken ones...Jason
It was the second comment or so on this thread, but thank you for the feedback! Would you still purchase an older 4.2 with lower kms then with no variator fix?
thanks!

Haha the budget brake and muffler for a Maserati is slightly off putting.
Yup, clears after one second. Should I be worried about this?

Personally I wouldn't be, no. Worth getting a second opinion at the next service but this sounds like a non-issue. Mine did it after the variators were done, and is still going strong at >100k miles

100k miles! Wow, I just got my check valves quoted for the cam caps and I’m hoping that prevents the issue altogether. Long live Maser 😝 (quote in Canadian $)
I’m curious if this variator issue comes up from lack of driving, causing oil starvation in the top portion of the engine? Purely speculation, but I daily driving my car (1500kms a month), I’m curious to see if this ever comes up.

My 2009 is 148983 so some 2009s are fine.

A 2013 should be safe, right?
Hello all first time poster here. I've been a long time lurker at this sight, and now with the purchase last week of 2010 S MC Sportline, a fellow Maserati fraternity member. I thought I would try and clear up some of the information (and misinformation) in this thread (and others) on the engines needing attention with the varators and retrofitting of the associated oil pressure check valve. This issue was something I took into consideration when searching for 'The Right' driver quality GTS.
I've attached a copy of the service bulletin from Maserati to the dealers on the issue, and subsequent repair. I have been a 30 year technician, and have spent the last 3 years working at the manufacture level as a Technical Service Manager for a region with 68 dealerships. I've had to read through and decipher hundreds of safety / product improvement campaigns over the years, and sometimes they can be convoluted and confusing when translated to English.
On page 4 the bulletin states as follows
" The 4.2 litre and 4.7 litre engine with serial number:
• 148697 onward, are already equipped with the new anti-back flow oil valves and the present Bulletin should not apply.
• 150070 onward, are already equipped with the new timing variators and with the new anti-back flow oil valves and the present Bulletin should not apply."
So it really has nothing to due with the year and month of manufacture. These engines are completed, then shipped to the factory and stored until needed. Then, as the cars are assembled, an engine is assigned, recorded and installed during the build. My particular GT, is engine # 161XXX, so I knew it was factory corrected with the oil check valves, and updated varators. If your car has the warranty paper work packet, the engine number is listed. The engine number is also very easy to see by jacking up the unit, and looking up on the driver's side rear by the cat, a very clear stamping on the block pad. In my particular case, build date was June of 2010, so some of the dates I've seen thrown around on the web mean nothing as to effected units.
Hope this helps other new potential owners of these sexy beasts, make educated purchasing decisions and pricing consideration

This is spot on, engines were not used in date order. My QP V Sport GT S was a 2009 MY of the new 4.7 facelift model. If you go by dates - this is too early for the variator fix, but as it was a new model, it was a surprise to find a 149,500+ engine number on a car built in July 2009.
