I have a low oil sign but I can't the leak. Now I thought it was the infamoun manifold leak so I had that all redone at Cartek in NJ which is a Fbody performance. A month has pass by and I get the low oil lamp. Once again I"m like 2 quart off. Where is the oil going?

 

If its not leaking,it is going out your exhaust.Worn valve seals,and or rings.

 

The heads have new parts.

 

That leaves the rings.

 

anyway to be 100% sure that its one or the other? How could I check it?

 

Compression check maybe? You can do your spark plugs at the same time.
