Added a half quart of oil after 500 ish miles, a lot of highway.
That may sound bad, but, ...
Before I discovered the EFE valve was being pulled closed all the time, I was adding a half quart after 60 - 100 miles.
Plus, seems like it is leaking less engine oil - I suspect due to less internal exhaust pressure in the engine.
EFE routes the ps exhaust thru a passage in the intake and out the drivers side.
I'd imagine there is a lot of build up at highway speeds.
(Not the smile I wanted, but I like it - it stays. LOL )
No change on the tranny leak, though- Goldie still marks the spots she has been in...
