Subject: Re: Oil pressure fluctuating...
WOW 100 psi is very very high - I recall the old saying if the pressure needle moves thats good [really?] but generally 20-25 is fine...
Never had fluctuations in needle readings but is this caused by filter in sump being clogged and then swirl in oil adding that effect in?...
My issue is how to keep the engine oil tight externally...
