Hi all,
Newish owner of a 2009 Granturismo S (4.7) in the UK.
Have looked through all previous threads and haven't found anything very similar so hoping someone can help!
Getting some reasonably thick white smoke on startup for about 5 seconds. More than you would expect just because of cold weather and I think it has a slight sweetness to it, inferring some coolant leakage somewhere I assume?
Checked oil both from cap and dip stick and no signs of any milky contamination, looks nice and clean.
Coolant was low when I checked a couple of weeks after owning, quite below min, topped up with almost 1 litre of coolant, and seeing a slow gradual drop over time. No obvious signs of leaking coolant lines after looking under the hood at startup and once warm.
No power loss in car, no fluctuating at idling, temp gauge never over 90. Fan does kick in on engine when stationary when it hasn't been driven hard though.
Background on car servicing which might be relevant - RHS Rocker Cover Head Gasket changed in 2017, Coolant Header Tank changed in 2019.
Would really appreciate any thoughts.
Thanks,
CT.
