Same cams for over 300k miles fitted 1970 Mk2's originals with holes in leading face of cam (thanks to Pete Green) first 100k wear was evedent 0.006" to 0.012" most wear noted on exhaust cams (opening against greater pressure) first pump fitted by the originator Herve" Hamon in 1990 whilst sleeving main bearing housings .Since p/p fitted less than a 0.001" on roughly the same time period.
When fitting the Honda P/P the first thing was to fit a wear to the suction of main P/P. this allows the oil level in the cavity behind flywheels to build up BUT not so high that it is higher than the cavity wall.
The tube can be seen with a hole very near the top and suction line secured to outside wall of c/case and set back into into the aluminum of the c/case as flywheel very close, set suction end to 1/4 of diameter of bore to the bottom of C/case for optimum flow.
