Probably compression in the 120lbs range on all 5 cyl., with a hot engine. The real test will follow the initial test, by adding a tablespoon of engine oil into each cylinder and waiting a few minutes. The oil treatment will coat the rings, and if the rings or cylinder walls are worn, the compression will increase dramatically.

Very few 5 cyl engines, or any other volvo engines for that matter, have worn cylinders or rings. The valves usually go out first.

If no one wants to replace the oil separator box, then get a can/bottle of AutoRx and pour it into the crancase. Follow the directions and make sure you drive the engine unitl the oil gets nice and hot every time.
This AutoRx will remove sludge and help the breather system also. It is not a cureall, but it helps.
