Have coolant in engine valley between heads any info greatly appreciated. System does hold pressure & only seems to leak during storage.

Hi there,

You will have to wash and clean all the coolant out of the valley, pressure test over a long time as there may be a very small leak or weeping gasket, you may have to pressure test for a number of hours if as you say the coolant only appears after a period of storage.
