A couple weeks ago i noticed that my car was running like crap. It will run great when i first start it up, then after it gets operating temp it runs really rough and sounds almost like a rod knocking! I went and flushed the cooling system like i do every couple months and i noticed oil in the water! Has this happened to anyone here before? Any clue as to what it is? Thanks in advance!

 

intake gasket, head gasket, cracked head, cracked block are a few possbilities.. any water in the oil?

 

no, thats what threw me off. there was no water in the oil. I started it again and it ran fine after it cooled a couple hours. Then after it got warm it starter sounding like a couple rods were knocking or the engine was gonna come apart.

 

have you tried trouble shooting? eliminated anything or suspect any thing? as it is now the list is pretty wide open.
