Hi,
After 6 mnths of worrying about Tuscan reliability, I've decided to get one--I also have a Ducati 916, so I'm used to living with a temperamental female
Anyway, I went to see one in an Edinburgh non franchise dealers, it's a Dec 200 X plate, with 8000 miles, one owner,Titanium 380bhp with red rose?.
No air con, or cd, which I would have preferred. The one thing I did notice was, when it was started, a fair amount of blue smoke came out of mainly the offside exhaust. Being a mechanic to trade, this worried me.
When I pointed it out to the salesman (ex TVR, and a nice guy)he said it was quite common, as it hadn't ran for a couple of days.
I can have the car for 29995 cash as I'll probably sell my TT private. Any views on these questions, or any other tips would be helpfull,
Cheers,
Stewart.

you're worried enough to post your concerns here so walk away, the right one will come along. I'm no expert on S6 engines but on a 'normal' car engine this indicates valve guide/seal wear

Mine doesn't smoke after being left a few days. Any blue smoke coming out of any car exhaust doesn't sound good to me IMO. There are plenty of good Tuscans out there. So get one of those!

If it was white smoke ,then it was just the huminity...(water "drops" inside the exhaust), so whille the engine temperature rises, the exhaust temp rises also,...and the water comes into air and white smoke comes of the exhaust(something similar when you boil water!).
There can be also some "water drops" left inside the combustion chamber, because here in england the huminity is very high after each night, so when you fire up the engine , the air/fuel mixture is also mixed up with these "drops" of the huminity. So it takes a few secs (and blip throttles ) to go off the chambers and the exhaust.

If it was something like blue smoke then:

1) there is an oil leaque and oil comes into the combustion chamber or
2) some of the spark plugs do not work properly (is "burned") or
3) the fuel is not burned properly,for a lot of reasons e.g the petrol is not "good" (that means that this guy does not use good petrol mixed with water or somethin...)
4) the "lamda" (L) sensor is not working right(propably form the huminity) so the air/fuel mixture is not right when the engine is cold.

That was a "soft" example, now if things are worse,then you do not want to know...
like:
5) the intake or exhaust valves are not sealing properly, so there is a leak during compression.
6) the ignition system does not working properly, so the ignition timing fir each cylinder is not right, as a result not right fuel/air mixture burn.

well ,
if the white smoke stops after the engine runs at its normal temperature then everything is fine.
if the blue smoke stops after the engine runs at its normal temperature then we shall asume that everything is ok
if the blue smoke does not stop after the engine runs at its normal temperature then...BAD News

Would Ted allow you to name the dealer .. maybe someone else would prefer not to buy it also if there'sa problem .. however it may be a useful bargaining tool - buy it cheap with a warranty and if the worst does come to the worst then it'd be rebuilt anyway .. just a thought.

Joo,
That's an idea, but I'd rather pay good money for a good car, that's not going to need major engine work.
I've seen posts by Claire at Dreadnought------I pass there a lot on my way up to friends in Killin, and allways thought the TVR sign was from days gone bye! nice to know there's someone nearbye who seems to know about TVR's.
I'll get in touch with them, and see if they know of any good cars for sale,
Stewart
