Oil light flashes and engine dies
I have a 2005 Mazda6 3.0 v6. 110k miles. It started with my car dying while driving on the highway and would not start. So far the things I have done.
1. Changed all the coil packs and spark plugs. (Valve cover o rings leaked oil into the spark plugs)
2. Replaced all gasket on the valve cover.
3. Ran sea foam and engine flush in my engine. (I did this because I noticed a lot of slug inside both valve covers)
4. Changed oil and filter 3 times till oil was clean. Oil kept coming out black. I used 5w 30 (Oil is clear now)
5. Replaced the PCV valve.
6.. Cleaned the MAF sensor.
I can get it to start up but idle is rough. The oil light is on also and I hear a slight knocking coming from the top of the engine. If I rev the engine up the oil light goes out and the knocking stops. If I shift to drive the oil light flashes, rpms drop to about 500 and then the engine dies. At this point I'm not sure what it can be and don't know if I should just take it to a mechanic now. Need some advice. Thanks.
