Valve Spring failure

[pjondeck]

I have a 2005 4200 Spyder cambio corsa.
It has 60Kkms on the clock and has never been "tracked" to my knowledge. I was taking a fairly easy cruise (it's hard to hammer it and keep the license), short story is I got a tapping noise that proved to be a broken outer spring on an exhaust valve. $6500 dollars Aust later I'm back on the road. Is this at all common, I believe not? Is there any point me talking to Maserati about it? I suspect not but interested in any comment. Thanks

First report in nine years of 4.2 coupe ownershipI have read, but Phil in New Zealand may be able to shed more light on the subject following his years working for Maserati.

I doubt Maserati will care a dot tbh.

That effin heavy for a $20 valve spring mate, I suppose they had to remove the cylinder head though..but still

That's the price of a second hand Fiat 500!

I suspect they drop the engine to get the head off. That's 40 hours by the book. I'm told.

Never heard of it with my experience with Maserati but always a first.
Like most jobs on a Maserati they are labour intensive and the parts are expensive.
Timing up the engines with dial gauges is very time consuming but the only way to get it perfect and for optimum performance.
Not just a case of lining timing marks up like on a Merc AMG.

Bad luck I don't think if it had been tracked or not would have had much bearing. Just one of these things.

Thanks for the replies guys. I've been on the road for a few months so sorry for the late response. First advice was that it was an "engine out" job but my repairer managed to get the head off without doing that. The parts alone from Eurospares to lift the head, replace the valve and put it all back together were over Aust$1000. Big job. I am a bit philosophical about it all but thought it early for a car with the miles to have a problem like that. While I was away having just shelled out the readies I was pondering moving it on, bit of a loss of confidence issue. Then I came home, opened the garage, took one look and fell in love with the Italian mistress once again!!
Thanks agin for your comments.

Stupid question, if there is enough clearance to get the head off without dropping the engine, isn't there enough room for a skilled mechanic to pop out the valve spring using just a spring compressor with the head in situ?

To get the valve spring out you have to get the cams off and the chains so for me I would rather have the head on the bench and check everything thoroughly.
Just my opinion though.
