i think i might be wrong
but the check valve is in the oil filter. if you car has the spin on type like my 92 190e 2.6. i've been looking for the upgrade filter
that won't let the oil back to the motor when you shut the car off.
so that when you first start your car in the cold morning it won't make the sound it makes for a few seconds.
