i just noticed while working on my cooling system that the left air intake sucked like a week vacuum cleaner while the right side not at all so i put my hand over the left side as expected the cat nearly choked while repeating the same no the right ,their was no difference in engine noise at all. the car seems! to be running OK apart from a water leak that seems , well it leaks on day and not the next

 

Normal operation, no worries .

Cheers

thanks Doug .seems strange to the layman though
