My oil pressure light stays on even after fitting a new one
I don't want to worry you but have you checked to see if the oil pump is ok, as if it has failed the oil pressure will be the problem not the switch which operates the warning light. ? Have you tried taking off the oil filler cap whilst the engine is running as if you do that you can sometimes be able to see ( with the aid of a torch/flashlight ) if the oil is getting pumped up to the timing gear, i.e. the camshaft and the valve gear, followers etc. If the oil is sluishing about at the top of the engine ( spitting out even ) then that is some good indication that the oil is being pumped up by the oil pump from the bottom of the engine ( where it is usually situated above the oil sump at the base of the engine) Furthermore...The oil pump 'pick up' pipe usually has a gauze filter attached to it, to stop any ' foreign bodies' entering the lubrication system if it has become blocked the oil flow into the pump will be restricted and could cause a low pressure warning, Unfortunately the only way I know to check this is by 'dropping' i.e. removing the sump which can be a big job depending on the access to it.I am not familiar with your model of car nor am I a qualified mechanic but know quite a bit about how engines work and how to fix problems. Also if there is insufficient oil in the engine this will cause the warning light to come on. Have you tried changing the oil as old worn out oil might also give you problems including wrecking your engine. I hope something I have said may be helpful, Good Luck...... Stephen
