Question about 2001 Land Rover Discovery Series II
I have a whistling sound coming from the engine anytime I am not accelerating. This is constant as soon as I start the engine. No leaks are apparent, however, I also seem to be losing coolant over a 3 month period. Suggestions?
Take a look at the belt see if it has cracks or worn grooves.. if it dose have it replaced. if it doesn't pull on the belt back and forth see if the tension pully is giving the belt tension( it supposed to be about 1/2 of an inche to an inch or try to turn the belt around to almost half way) if not replace the tensioner pully. if good check the free pully by starting the car and spary a bit of wd40 on the center of the pully if noise disappers replace the free pully. if not see ur local auto shop..

It's possible you may have a bad PCV valve. While engine is running and producing the sqeaky noise, loosen oil filler cap to relieve any pressure that has built up, to see if noise goes away...
also run engine until noise is apparent, then turn off engine and loosen oil filler cap, listen for excessive pressure. If so, probably PCV Valve
