docc Posted March 11 Report Share Posted March 11 1 hour ago, Scud said: I chased a low pressure situation for a while on a 2003 LeMans. Turned out that part of the gasket (as pictured in Rolf's post) was missing. This internal leak allowed oil to escape but maintained low pressure - the light would sometimes come on at idle, but would always go out with a blip of the throttle. It ran like that for a long time without any failure, but I did find excessive wear on the washers on the rocker-arm shafts. The problem with the warning light is that it only tells you about dangerously low pressure. If you care for a lengthly and somewhat philosophical exchange about this issue, see my topic about it at: "Oil Pressure vs. Oil Flow" So, with a "Roper Plate", two of these would sandwich the plate above the spacer? 1 Link to comment Share on other sites More sharing options...
