Oil Pressure Problem?

You could have a low oil pressure issue. It's hard to tell with just a light. You really need to get it to a mechanic for them to hook up a guage so you can find out exactly what kind of pressure you are running. It could be a pressure problem or it could be a faulty oil pressure sending unit. Only a knowledgeable mechanic can tell you AFTER running some tests.

IF the oil pressure is running low, then there is a couple things it could be. Yes it could be the oil pump. Oil pumps usually last nearly forever though. More than likely, you're main bearings are wearing thin. While replacing those however, it's always a good idea to drop in a new pump since you're right there at it. With 130,000 miles, your bearings have given you plenty of good service, so don't feel bad. Good for you for changing your oil regularly. That's the only reason the bearings have lasted this long.

If you don't want to, or can't afford to at this time to put the money into it, may I suggest another oil change. Change to 10W-40 oil. I can't guarantee t, but sometimes if the bearings aren't too bad yet, you can get another five or ten thousand miles out of the bearings by going to the 10W40. I'm afraid though that if this doesn't help, running it too long with low oil pressure could damage more than the bearings.

The next option you need to look at is, how much do you like this car? If you really like it and you decide to go into it for the bearing. I recommend finding a good mechanic you can trust and go ahead and spring to get the engine completely overhaul, or rebuilt as some people say. With that many miles, even it does have enough power, you can bet that there is considerable wear to all the bearings throughout the engine and the rings. A good mechanic can go through that engine and return it to better than new condition.

Good luck. Maybe it'll turn out to be just the pressure sending unit.

I'd have said it might be the pressure switch except for the rattle. Both together indicate that it isn't building up pressure properly. It's possible that the replacement oil is too thick, in fact, not too thin. It might in fact be the oil pump that's going home. You could do with someone putting a proper pressure gauge on it to see what's actually happening. Back to the garage and insist on seeing them do the checks.

It could be an oil pressure problem or just s falty sensor that is making inaccurate readings. On you next oil change go with strait 30 weight this will boost the pressure a little and may cure the problem, Only do this if subzero temperature are not present in your climate.In a rare circumstance this could indicate a dislodged oil gally plug or some type of internal leak.

Good Luck

Take it to a mechanic & have him check the oil pump. If it goes out you could loose an engine. Synthetic oil should be good, but I did loose a engine using synthetic oil & no oil light. I perfer to use Pennzoil high milage oil on anything over 90,000 miles. It comes in a copper colored bottle. Please go see a mechanic soon.

most of the time its probably an oil pressure sending unit. its a little peice very close to your oil filter with a wire connected to it. without this part you will get faulty readings as well as irratic oil pressure. they cost no more than 15 or 20 dollars. most commonly they cost about 5 and can be dont with hand tools in a half hour.

You could have an oil pump going bad. On a car with this type of mileage this is a common problem. The job is easy but dirty, if you have a handy dad or friend it is only an hour job, and not to expensive.

its probably the oil sending unit thats bad, but when you go for a oil change, ask for 10w30 instead of 5w30, the 10w30 is a little bit heavier and thats better especially in the hot summer.
