It actually would take 2 filters, one return low pressure from the cam cavity and one on the discharge high pressure.
There is an existing metal filter at the high pressure exit on the pump.
I believe but cannot confirm that there are individual metal filters on individual injectors as well.
Wonder if they are good enough in particulate size and PSI.
As they load up, wonder if there is enough surface area to continue to
pass without pressure drop and at those PSI's/BAR's...it would become
a balloon quickly if plugged.
$$$$ would factor in the kind/quality/etc of any filter in this type
of system.
Again, impossible to filter debris inside the cam cavity. Married with
very poor lube flow, as it is recycled with little 'fresh' fluid.
Unless the input port and exhaust port are on opposing sides of the cam
cavity
Even then, the basic problem is still there.
Wonder if they had the piston captured like a ICE's crank/rod/pin/piston
would have helped or solved???....but then $$$ becomes an issue...
