sounds like its got a fair bit of back pressure.
could be the start of a headgasket failure, it may be worth your while having it checked at a garage to see if gasses are present in the cooling system, also check the coolant for oil in the mixture.

like perry said they test for gasses in the coolant. with a blue fluid in a tube if it turns bright yellow/green there is a head gasket fault dont have to b down on power ether.
