Head gasket

[2100ccrider]

My VR V6 ute is using a little bit of coolant.Are they prone to head gasket problems eg coolant slowly leaking into a cylinder.I can't see any leaks on outside of engine.Engine has done 300k and has not been overheated.

Yes, the inlet manifold gaskets are prone to failure and cause coolant loss
