The car is a 2000 impala 3.4ltr. Heads were changed. New radiator and fan also. After the car ran 4 fifty miles I changed the oil and filter. Suddenly, the oil light blinks, but there is ok oil level. The car still runs great/ not hot, but the red low pressure light blinks. Is it possible that during the head job, I might have dropped debris(gasket material, silicone, etc.)That may have clogged the oil pump/ strainer? And if this is the case, how 2 drop the oil pan 2 clean?
I am a broke do it yourselfer with some experience, and this is the only car I use 4 my family.

I would recommend checking the oil pressure. You can do it with a mechanical gauge from the parts store. Also, if you hear no knocking or ticking, chances are the oil switch is bad and sending a bad signal to the gauge.

Let me know what you find.

Thanx! However, a parts store check is not an option. I live in on an island in The Bahamas. As the car is a daily necessity this will not work.
Can you tell me the best way 2 drop the oil pan with basic tools?

If there is no noise, don't drop the pan until you check the sending unit. Chances are it is bad.
