In VA, till friday and planning pulling the {3A}heads beginning SAT morning...



Tested all cylinders once, and pressure rose and held steady in all cylinders.
Tested Again, using oil, and pressure rose and held steady in all cylinders.

Pressure fluctuated + 0 to +7(Hg measurement) AT most as motor was cranked, but it rose and held steady. SOMEONE lost the numbers, but pressure rose +10( ) total most between highest and lowest reading cylinders.

I 've seen that happening when testing the not failing, but the lesser performing valves of the same quality in mechanical fuel pumps.

??...to the machine shop for a cylinder head updo?


Gonna let everyone know the deal soon as I get at it
