was at light, stopped in drive. oil pressure dropped from its usual 18-20 to zero while sitting there. RPM at 350 running fine.
shifted to neutral. pressure returned to normal. RPM at 500
all the way home this continued, running fine, better than before my recent repairs. idle when stopped in drive is slightly lower and smoother than before my recent repairs.
pressure is normal (20) when driving, but less responsive to acceleration than it was yesterday, after repairs. only goes to 23 or so when accelerating, yester day it went to 30-40 when giving gas.
when sitting in drive the pressure at zero, it sometimes is jumpy, jumping up to 3-4, but mostly at zero, shift to neutral and rpm increases amd pressure goes 18-20, normal.
could this be my pressure gauge?
oil pump itself?
oil screen clogged?
yesterday I repaired the ccv vacuum prob and other probs, could these vacuum repairs have broken crap loose and this just be a minor gauge or screen prob?
my book does not even describe pressure gauge or location, do you know of better manual than Haynes?
well I m not making it up. I was wondering if the gauge might have went bad but my book tell me nothing about gauge. it says screen may be clogged but doesn t describe screen.
Blanking the inlet screen has nothing to do with the pump failing internally. It causes suction flow to be lost. This happened on my 1976 Fiat and my Dad’s 1963 Dodge. Both times the pickup screen was 75% blocked. Mine with paint that flaked off the inside of the pan, and the Dodge with carbon crud because the oil wasn’t being changed enough.
oil was changed about two months ago and has stayed fairly clean, but may have broken some crud loose when i poked thru the clogged grommet, in the top of rocker arm/valve cover, that my CCV vacuum tube goes into i guess that tube could have sucked some crud into crank case too, like i said, i don t really know how it works
no prob. any help is greatly appreciated. im getting all the info i can before i get into it.
its 96 degrees right now so i m reading my manual, which is not helping much and listening to you guys in the hope i ll have some clue later today
Depending on the manual it may have a section titled Component Location or something similar. Also try the auto parts store sites some of them may have a component locator.
