Oil Pressure Light

I searched the topics and didnt' find this same question. My oil pressure
light stays on for 10-15 seconds sometimes. Sometimes it goes off in a
"normal" amount of time.

When the light stays on there is a "ticking" coming from the engine. As
soon as the light goes off the sound goes away. So it would seem that the
whole engine isn't getting oil right away. Although as I said this doesn't
occurr all of the time.

It is a 1997 1.9 liter with about 50,000 on it. Trying to get an idea of
what this is gong to cost to fix before I take to the shop.
Thanks

 

More info please: Oil level checked on level ground and if so is it up to
full mark? What spec/weight oil? Filter and oil changed regularly at 3K
miles? The ticking is usually a sign that the overhead cam and valve train
in the head is starved for oil. Could be a defective pump, but at 50K
miles, I'd bet the oil is low or the oil was not changed regularly so the
oil pickup is clogged. You could try an engine flush, but they have been
known to cause leaks and possible damage since you are basically pouring a
quart of kerosene into the oil crank case. You could also try to use a good
synthetic oil, like 5W-30 Mobile One. You might also try using a small
amount of oil additive, like Marvel Mystery Oil, when you put in fresh oil
for the next few oil changes to see if it helps.

Oil is full on level ground. Usually changed every 3000-4000 miles. It is
about due for an oil change so I will try your suggestions.

Thanks
