Change oil pressure sending unit. remove oil fill cap start engine to determine if oil pump is delivering oil to rocker arms. it it easer to tell if you remove one valve cover and then start engine. if rockers are not recieving oil change oil pump and clean oil strainer in oil pan

Engine oil mixing into coolant

The only place, oil and water share a gasket is the cylinder head gasket, oil and water galleries run through the engine block and head via the head gasket. The cylinder pressure will be OK, it's the oil pressure that's putting the oil in the coolant, the gasket has gone between the water and oil galleries or there is an internal crack (unlikely). A coolant pressure test should show it up.

I own a 1990 Mitsubishi Eclipse and it has a full amount of oil but the pressure gauge is showing a lower pressure than what it used to. Could it be the oil pump going out? Im running Valvoline 5W-30...

take it to a shop have them put a manual guage on it if it has low presure you need a new oil pump and new bearing but it is very bad to drive with bad presure

Oil guage drops then goes to high range

sounds like your sending unit needs to be replaced cheap fix and if your oil pump losses all its pressure you will begin to hear knocking coming from your motor from the top under the heads.

98 altima oil light on and off oil level fine car restarted and

If oil pressure is LOW this vehicle has a safety feature that will prevent vehicle from starting.(check oil level before you start) Now what I wan't you to do is to have the oil pressure switch checked or changed. This may be the reason why this vehicle is not starting or it can also be that the actual oil pressure is low. To check the oil pressure of the vehicle you will need an oil pressure guage. Remove the oil pressure switch and connect guage to oil pressure hole and check oil pressure while cranking vehicle.Some pressure testers can be connected to oil filter housing either is fine. If this vehicle has low oil pressure the reasons for that are bad oil pump, clogged oil pump pick up(from lack of oil change/poor mantainence) or bad connecting rod and main bearings but this usually have a warning from before (the engine will sound loud by knocking /clicking-tapping noise) It this was happening you may need to rebuild this engine or replace it. Good luck and Thanks for using FIX YA
