Just as thought...it uses the fuel PSI to self shut along with a coil spring
That is where the shock wave is generated...when that valve shuts and since
via the fuel flow/PSI, directly linked or back into the fuel lines
Any have tossed the cam lob as the potential culprit. That is where
my initial thoughts were, but after learning how it works, of course not
there...but...a new one creeps in...
How is that lob lubed? Assume fuel and then where does it come from and
it should have a return or relief back into the fuel system somewhere
Asking because the cam shaft is also lubed some how. Then ask what kind
of bearing is used? Is that lube under the same PSI as the incoming
fuel to the piston/chamber?
Am getting at whether there is a potential source of contamination from
that bearing and it's seal?
