Sounds like a plumbers tool bag

[diggerjohno]

I have had my Tuscan for about 4 months now it sounds quite rough after i have just started it running on idle. Once its up to temp it sounds great is this normal?

TADTS!

Can't say mine sounds brilliant when cold either.

So your not alone.

'Bag of spanners' is the useual term. The only comment I got, was from my children who asked if 'it was meant to sound like that', after many years of starting up Porsche's.

Its the timing chain. Sounds worse than Trebant when cold.

Best advise is to get Carbon Can exhausts, then you cant hear anything at all!!

No it's NOT.
Mine was similar before the last service, the tappet adjustment was way out.
Get them checked asap.

Definitely not normal. It will be noise from slack in the tappets / finger followers. They will be wearing more quickly by knocking. Timing chain should not be temperature sensitive but can tap the top of the cam cover if too slack.

Mine used to be quite 'spannery' when cold. Following a head gasket replacement it now sounds quiet as a daisy when cold - hardly any of the bag of spanners sounds. I suspect TVR replaced some of the top end at the same time as it had sounded like that since new (fine when warmed up though). 13k May 2004 car BTW.

mine used to sound like the proverbial bag of spanners when cold, improved significantly when oil warm and revs at 900rpm.

As long as it disappears when engine is warm/ hot then I would not worry too much as I was very much under the impression that they all do that. It will make you feel better to know that Al Melling covered this briefly on his talk on the Speed 6 engine and he mentioned that it was supposed to sound that rough on start up!

Just been out for another run, dont think its anything to worry about as once the oil temp is over 40oC it sounds fine. Might get it checked out all the same. Better safe than sorry!

David is right, three engines I have seen, the same thing!

[sideways mostly]

my 2002 spec 4L had the bag of spanners sound with 3k on the clock-my 05 3.6 ( probably 04 build) has 13k on the clock and sounds quiet when cold.Either its build variation or some changes to components so it probably depends on when yours was built.Never had a problem with the early engine-once warm sounded grand.

first tuscan did this timing chain nonsense aswell, I just epoxied a strip of cut down timing chain guide from a ford v6 duratec engine to the cover and it cured it.

Mine is much quieter since it had it's shims checked and changed where necessary.
