In the UK (and I suspect the US) the machining of the cam caps and fitting non return valves can ONLY be done by Maserati GB/N America.It is not a DIY job. In the US the variators were done under warranty even when out of warranty. Not sure if they still do. Variator failure only affects 2007/2008/2009 4.2/4.7s's before the golden engine number as previously mentioned. Yes Variators are now upgraded when doing a full. variator failure replacement job .I like this. In a few words you consolidated 100's of posts on all the forums. You could also do the cam caps yourself for <$1000 here in the U.S. from what I understand.
Let me ask this. I have read that cars after September 2010 or 2011, can't remember which, have the upgraded variators and cam caps. I also read it started in the 2013 cars. What are your thoughts on this?
