Check oil light comes on in my 1994 olds achieva

check your valve cover gasket there my be oil getting on your plugs

It could be coming from the oil filter itself. Sometimes when changing the filter, people can overlook the fact that the gasket from the old filter may have stayed on the engine block. Then when the new one is installed the gaskets double up and it doesn't allow the filter to seal. Causing the leak.

did you check the switch? (dash light dimmer)

Start at 5qts. It should take 5 1/2, Put 5 in, start it, let it run for 30 seconds, to fill the new oil filter, then shut it off and check the oil level, should be about a half quart low, then add what you need

Have you checked the turn signal fuse? If it is good then i would replace the flasher.

The best place to start ,Have a diagnostic scan,i have heard Auto zone dos this 4 free,other ways about 65 to 85 $ it could be faulty computer ,or ground,Hope this saves You some time and headaches , if it is a ground it most likely the one that goes to computer.if you need more help please check back ,let us know how we are doing Thank You

The head light switch is the problem here,it controls both.

raise car, remove any obstruction from out of the way of the oil pan. if you arent pulling the motor it will mean you need to drop the front k member. after that remove all bolts from pan, pry it off with a putty knife, remove old gasket with razor knife, reapply gasket, possibly adding RTV silicone if your car needs it. reverse all other steps and you are clear. unless you know for sure its just the oil pan leaking i would suggest changing front and rear main seals on the crank as well.

this sounds like a faulty oil pump down in the pan when u come to a stop so does the pump might want to get this checked out by a mechanic cause it could always be something else too hope this helped

check for fuel pressure and vaccum leaks could be many things hear are just a couple please rate -jeff
