Engine Knocking, just need some ideas Options

[94st_santos]

Well I took my car for a trip, and probably the last. My engine starting knocking really bad. Before it was a tap, now it is definitely a hard knock. It sounds really bad. It is coming from around the valve cover but then again it is sort of from the middle of the engine, hard to tell. I just need some thought on what it might be not exact. So I can kind of get an estimate of how much this is going to cost to fix. Hopefully I don't need a new engine, it would be nice, but I don't have the money right now.

thanks in advance

i'm willing to bet its a spun bearing. how sure are you that your oil wasnt low prior to this? i mean if it was full last month, then its possible you have an oil leak you dont know about and it got low and then bam spun the bearing, and thats why it was low after the bearing spun. check around the engine for oily sludgy stuff, i bet you had a leak you didnt know about.
