how do i test the oil pump pressure,
In a previous question, I asked about lifters as I have a tappet sounding
noise when the car runs at tick over but goes away at the mid-range speed I
asked about lifters last time but wonder if its more to do with oil pressure.
quite a loud tap not a tap but not a loud bang either, pushrods didn't sound
like anything unusual either help, I thought it might be a collapsed lifter but a
stethoscope on the valves and pushrods sounded ok, I can't hear any noise
from other parts of the motor just loud tapping when running.
