Sounds to me like the Volvo engineer is short of work!!! Hang on first regarding the gasket and fix the cooling system.

Ask your self is te signs of oil in the fresh water cooling sytem or signs of oil on the bottom of the pressure cap..If not then I think you eed to look at how the caps and expansion bottle are fitted as it will not be the firast time I have seen an expansion bottle incorrecty fitted with the wrong radiator cap so preventing watr to draw back to the engine on cooling.
Perhaps if you detailed exactly what was fitted as I suspect that the problem regarding pressure may be no more han normal activity caused by incorrect components . Can and does te water foow back to the engine when it cools from the expansion tank.???
IF no traces of oil or sludge around the pressure cap then the gasket could b OK.
