Hey guys my car has been eating up oil lately. I have to put a quart in about once a week and a half. Here is my question. Is the oil getting past the piston rings or is it getting past the valve seals? There is a set of fresh 96 heads for 250 that I was thinking of getting if its a valve seal issue. But if its the piston rings then Im just gonna have the block rebuilt. Any help would be greatly appreciated. Thanks.
