89 FORD E-150 w/5ltr EFI engine & AOD Trans w/110,000 miles. A qt of oil disappears every 100 miles. It's not blowing smoke or coming out the tailpipe, engine is not leaking & it's not in the radiator. Oil gage stays in center. Where is it going? Also, it drastically loses power up hills and shift into overdrive but instead of overheating the temp gage goes down below the N in normal returning to M when over the hill.
I just had a major $800.00 tune up which included new erg valve and it didn’t help al all. I’ve been to 5 or 6 auto mechanics and their answer is “I don’t know offhand but leave it overnight and for a hundred bucks or more we’ll diagnose it for you.”
