PCV Breather System Kit - 1999-2001 C70 S60 S70 V70 XC70 Turbo

Properly servicing the flame trap / crank case ventilation system generally means replacing all the system components and can be fairly costly as labor as the intake manifold must be removed. Generally speaking the flame trap system components need to be replaced about every 100K or so depending on the quality of oil used, oil change intervals and driving conditions. The plastic tubing and fittings get extremely brittle with age and also becomes restricted internally due to oil deposits and sludge forming inside the tubing. The restricted breather flow results in excessive crank case pressure, which in turn begins to force oil past seals. If left unchecked, seal failure can occur which in extreme cases could result in rapid loss of oil pressure and catastrophic engine failure.
