Welp, when I'm wrong, I'm wrong. And that's often!

The E58 on the Diplomat body does use the oil "check valve", it's just mounted on the cooler instead of at the back of the block like on the B body. I must have been really tired yesterday to miss that!


Looking for 1975 through 1978 B body 4 door sedan sheet metal or parts cars - monaco, fury, coronet. Please let me know
