Nissan CA18DET AN10 Cylinder Head Drain Kit

The CA18DET engine suffers from a common issue of improper crankcase ventilation where the cylinder head will pool with engine oil at prolonged high rpm use. This causes oil to be forced out of the valve cover breathers, resulting in the intake being flooded with oil or your catch can being filled. This can cause bearing wear due to oil starvation if enough oil manages to escape the engine through the valve cover breathers.

Fitting a head drain kit allows for better crankcase ventilation between the cylinder head and engine block as well as providing additional drainage. 

This kit consists of :

• 2x Mild steel AN10 sump fittings
• 2x Aluminium AN10 head fittings 
• 2x AN10 Lines with 90* fittings
• 2x Heat Sleeves
