car problems

Sounds like the oil pump went out and now the engine is knocking or a head gasket blew. Oil light on is serious. Knocking is bad. You should of had that checked, any knocking noises need immediate attention. F

First by stop driving it. Tow it to a shop, do not drive it anymore.

well like a said the light only flashed and never stayed on more than a minute until now but i had it towed to my house and my dad came to look at it tonight, he said that it looks like it not getting any oil to the rockers.i had taking it to orielys to have the computer read and no code for the oil or anything related came up. but i am definitly gonna get the pump replaced and more than likely the head gasket at well to be safe. again thanks for any input

If your top end is knocking look at the rockers and see if one is nearly off, crooked looking, may have a loose one, its possible, not likely but I would look if any noise is from the top end. you can hook up oil pressure gauge to test oil pressure to know if oil pump is bad or needs attention, and a compression test on all cylinders at the spark plug holes will show a bad head gasket most times and a test for exhaust in coolant will show if head gasket is blow in the test that compression test will not show, so I would test this first before doing that work.

I have also seen cam lobes pop off (Pontiac 4 tech) and make all kinds of racket, and if not turned off will bind up on other lobes and pop them off too.

Now if, saying if it was a bad oil pump and its knocking at the bottom end then your left with rebuilding this engine as the knock will likely be a rod bearing spun and loose but can just replace the spun bearing if you have to, may need a thicker one.
