I do believe that you're all correct. Never dealt with an Escort, but mechanicals are all the same. I like those readings, tapering right off from the cam pulley. Those readings are a story book themselves. Head might be alright, might be scrap. I would imagine block's aluminum too. Well, certainly don't have to pull the motor to replace the head gasket - just the hood to get at it properly, and may not even have to do that (never touched an Escort). I would imagine going to have to take the cover off of the motor for the serpentine belt that drives the cam because going to have to time it after put back on (doubt seriously has a chain, gotta be a belt). Check the idler pulley between cam and crank pulley to make sure is good before button up. Take that head down to a machine shop and have it checked and/or decked if needs it and is cheaper than buying a replacement. If need a replacement, I'd be leary of buying from a bone yard since are probably throw away's, as someone else said, and that's probably one of the reasons ended up in a bone yard to begin with, and would certainly have to be checked/decked as well. That's pretty interesting that compressions drop off at the cam pulley in a linear manner like that. Engine overheated? Aluminum block and head expanded, contracted while cooling and now head bolts got loosened by belt movement/vibration? Maybe just a head gasket, but gotta pull the head anyway to replace it, so have the head checked for warpage, and if can be decked (if cheaper than buying a replacement). No big deal if was cast iron block, may not be a big deal for aluminum. Probably got the car cheap, and if have to invest in a head (and just may not), probably still cheaper than buying a new car. A head job aint all that bad. Mmm? Something about those words. Ha Ha Ha Ha.
