If your 85 Buick Regal is having oil pressure problems, here's what you should do instead of trying to "prime" the pump:
1. Check the oil level: This is the most crucial step. Low oil level is the most common cause of low oil pressure. Add oil if needed, ensuring you use the correct type and amount specified in your owner's manual.
2. Check the oil filter: A clogged oil filter can restrict oil flow. Replace the filter with a new one.
3. Check the oil pressure gauge: Is the gauge reading zero, or is it simply low? A zero reading suggests a serious problem. A low reading could indicate several issues.
4. Inspect the oil pump (if you have mechanical skills): This requires removing the oil pan. If you're not comfortable doing this, take it to a mechanic. Examine the pump for damage or wear.
5. Check for leaks: Inspect the oil pan, filter, and oil lines for leaks. Leaks will lead to low oil pressure.
6. Consider the oil pressure sending unit: A faulty sending unit might give a false reading, while the pressure itself is fine.
7. Have a mechanic check the oil pump: If you've checked all the above and still have low oil pressure, it's time to get professional help. They can diagnose the problem more accurately. The problem could be a worn pump, a blocked oil passage, or something else within the engine.
Attempting to "prime" the oil pump by pouring oil directly into it is generally not recommended and could be counterproductive. It's unlikely to solve the underlying issue and might even damage the pump or engine. Focus on diagnosing the root cause of the low oil pressure instead.
