Oil Backflow Prevention 993 Turbo - Engine Side - Prevents Smoking at Startup

Description

This oil backflow kit incorporates a check valve between the oil tank and the engine which prevents the smoking on start up for turbocharged 993 models.

Perhaps you have installed a pressure side oil backflow kit on your turbo model but are still experiencing smoking on start up. The issue may be on the suction side. The problem on the suction side is due to the oil tank sitting higher than the engine oil pump. Gravity creates a positive pressure on the pump and slowly fills the engine case with time. The case fills up and eventually pushes oil into the catch tanks on the hot side / turbine side of the turbo charger. Once the car is started, the cars smokes very heavily which is often misdiagnosed as a defective turbocharger.

Sold as a complete kit. 1 necessary per car.

Recommendation: It is best to address both the suction and pressure side to prevent the issue entirely on turbo charged models. We also sell a pressure side (turbo side) backflow kit under part # FVD20799310
