Pressure in motor - knocks when I shut it off
As this happened to anyone? My motor makes this wierd knock
after I shut off the motor, it does it for 15 - 30 sec after the motor
has been shut off. I have a small block chevy, with breathers on
both valve covers. One goes back to the base of the carb.
It doesn't do it all the time, but 50% of the time, when I shut off
the motor, and a few times while ideling at a light, you can hear
this knock? Any ideas? Obviously, nothing is turning or moving
when I shut it off, so I just assume its pressure in the motor that
eventually goes away. - - -If it is pressure in the motor, how can
I relieve it, so it doesn't knock anymore?
