I have a 2004 Ford Escape, 3.0L AWD, 180,XXX miles. Last owner ran it hot, now there is water in the oil and it overheats. It does run, but runs rough with low power and eventually overheats. Ran a compression test and the outcome is as follows: 1-183 psi, 2-120 psi, 3-103 psi, 4-155 psi, 5-125 psi, 6-95 psi. I have a few questions: 1) Should I pull the engine to remove both of the heads? I've heard it can be done with the engine in, but it is very tight. 2) If I repair the cracked heads, or bad head gaskets, should I install new cams and assembly (chain, guides, etc.) with it having 180,xxx miles on it? 3) Should I just look at replacing the entire engine instead of repairing? 4) If I do make the repair, is there anything else I should replace while I am this deep into it?
Thanks in advance for any help!
