Car Forum / GMC Cars / November 20051989 cavalier oil pressure
i have an 1989 cavalier Z24 2.8liter MPFI V6 5 speed. with aircondition( ive called many parts stores) the oil preasuse gauge freakes out after the car is at normal running temp when siting at an idle. when you press the clutch in and let the car go back to an idle the oil preasure gauge goue from about 3/4 (where it normaly sets when running with a load) to 1/8 to 1/4 some times making the engine stall. what might be the couse of this. ive been told many diferent things.anything from the gauge to the camshaft and oil pump. i dont know what to belive please repl -- bmxbassguy I had an '88 and it was the same way. Hot idle the gauge was around 1/4 or a little lower. I think there is an underlying issue causing the engine to stall. Do some simple things: Check fuel pressure Check for vacuum leaks Check/replace ignition components Change oil, oil filter and flush the engine. Change air filter Clean throttle body, IAC pintle and assotiated passages Steve > i have an 1989 cavalier Z24 2.8liter MPFI V6 5 speed. with aircondition( ive called many parts stores) the oil preasuse gauge freakes out after the car is at normal running temp when siting at an idle. when you press the clutch in and let the car go back to an idle the oil preasure gauge goue from about 3/4 (where it normaly sets when running with a load) to 1/8 to 1/4 some times making the engine stall. what might be the couse of this. ive been told many diferent things.anything from the gauge to the camshaft and oil pump. i dont know what to belive please reply > -- > bmxbassguy [quoted text clipped - 3 lines] > > Send from http://www.carstalk.net i nave put an KnN cone filter on car. there are numerus broken vacum lines. brand new oil, filter, and has been flushed thank yo -- bmxbassguy |
