[urq] Gurgling noise in cabin...

[Louis-Alain Richard]

Thanks for the suggestion Brett, but the car "raced" twice with that air in
there... so it can't be harmful.

I can't imagine an air pocket in the engine, I just bled the radiator two
minutes ago via the top purge valve, and there was no air, only coolant. And
this morning, the system was still under pressure, so there's no leak.

I'll ask Vincent, the owner of the track, he was a Audi dealer in France
before coming over here in 2000 to build Mecaglisse. He knows these cars
very well. He had a Sport Quattro until 2005.

Or there is an air pocket in the engine as well...?

Might want to sort out coolant system issues before you go racing?

Seriously, take it to a local shop in town and ask them to drain+save
the coolant, vacuum-purge and re-fill. Problem solved in 15 minutes.
