I should add that as per previous posts I've made about this engine,
after driven a while, the engine will blow compression gases into the
coolant. The main reason for taking a compression test is to establish
a base line though even if some loose head nuts are loose, tightening
them may not change the compression results. i.e. the cooling system
gets over pressurized after I drive the van for quite a few miles.
