So trying to figure out why my oil light flickers and goes on and off mostly when accelerating. Seems to have started after transmission rebuild. I know shouldnt have anything to do with it. I do have a guage also that connects at hole above oil filter. Also where is the light connected to so i can check the connection. Its not where my guage is connected. The engine is a remanufactured one that i have owned for 8 years but haves less than 10000 miles. 71 skylark 455
Not a dumb question. Passenger side of block above the oil pump housing. If you have a gauge connected there, is it electric or oil line? You will need to "trace" the light wire to see where it is connected to the block. (dark green wire). (it is remotely possible the wire is not connected, but is making contact/grounding, completing the circuit .)
This is a must. (not mine) https://www.ebay.com/itm/1971-BUICK...939556?hash=item5d7dd303a4:g:sM4AAOSwsEhbCFCR
I actually have one. What i dont understand is the only thing i have connected to the threaded hole above where the oil filter sits is a copper line to guages. I have read about teeing off at that point for a light and guage but i only have a guage connected there. When i get home i will trace from the light to see where it goes .
That's exactly what is happening. The idiot light sender supplies a ground to turn the light on. Whoever installed the gauge probably left the wire swinging in the breeze and it is intermittently grounding on something metal. If you want the gauge and the light to work, use a brass fitting tee. There are a number of ways to do that. Oil pressure light wire should be dark blue,
Thanks very much to everybody . The blue wire along with others had worked its way to the manifold and melted the insulation so bare wire and grounding was the problem. Glad it wasnt an oil pressure issue$ .
