My 92 Lumina has sprung an oil leak! It will go through an entire quart of oil a week, only running an hour a day. the oil only seems to be leaking when the engine is running. All of my valve covers are in good standing, and the leak is not at the tranny, or oil pan. In fact, when I popped the Hood, the oil was all over the engine block. EVERYWHERE, there was a small puddle of oil near the lower manifold, but it may have just dripped down and collected there. Has anyone had this problem in the past? Is there other spots oil can leak that would cuase it to coat the engine in oil other than the manifold? Thank you

 

My guess is oil filter

 

I Checked the oil filter this morning, and it was fine. no evidence of it needing to replaced or it being the source of the leak.

 

Try to put a new valve gasket cover and check for oil leaking again. Probably, your valve gasket cover failed.

 

Have you not looked for it with it running?

 

After Degreasing, I ran the engine, and dicovered that it is the lower manifold gasket. I have a lot of work ahead of me. Thank you all for the suggestions, as i took a more in depth look at the oil filter to fine a small crack in it, but it wasnt the main source of the leak.
