I agree I suspect I still have a problem and may need a second replacement engine. Your question about Liners, suggest you google open block design like "ralph7up" suggested above. The old school way is individual steel liners in each aluminum bore but the Escape has an open block design. All 4 bores are in a block of steel which is installed in a large cavity (open block). It's the design of the liner block of steel and the way it is sealed to the aluminum block and to the head that are the problem areas. The design issue, Ford claims, has been addressed and cracking in the liner walls between cylinders may be cured now. The sealing issues still remain in my mind. I have been a long time Ford owner, 17+ year old Ford Explorer, plus another Explorer, a Focus, and a Mustang but this Escape may well be my last Ford.I just re-read your reply, if the coolant is still going down ( even at slower rate ) you still have a problem. My replacement engine is still at the correct coolant level, then again it only has 350 miles on it......decisions decisions on whether to keep my Escape.
