    Well got everything off pans off nothing in it besides oil little sludge. But not bad . Burnt on one side guessing that's where the small leak came from .

    Day2: remove cylinder head (possibly)

    I find an electric impact is handy for removing head bolts. Harbor freight has one for $50 and it's been very handy for me.

    I've always removed it once the head is out of the car.

    Would just come right out if you have all the studs removed

    I couldn't get the last bolt on the timing cover off the one way down by the water inlet from the heater core outlet hose . No wrench fit and a socket was to big

    iirc that is a stud that acts like a bolt for the water pump. The nut that holds the timing cover should be a 13mm or so. Maybe 10

    I ended replacing that with a bolt since I left my belt cover off

    I forget what size it is, but a wrench will fit. It's a PITA but it can be done.

    What about the metal pipe connecting the exhaust and intake manifold and some vacuum lines I believe ? I can only get the exhaust side out . This car . I swear . The big bolts that look rusted on come off with no pressure then the nice shiney bolts like nope I'm not moving

    I found it "easier" to remove that motor mount & jack the motor up and down to access the various bolts.

    I didn't have the oil pan off. I jacked it up on that side. It doesn't hurt anything. I just put a wood block between the jack and the pan.

    Without the mount you can also let it drop a little. That tiny amount helped me access some of the bolts.

    By the tranny ? I dropped the oil pan to check for sludge or any thing falling out of it . Although the connecting rods I think they are called I can wiggle them is that normal ? If u drop ur pan what ever that shaft is not cam shaft the other one ? That connects rods to Pistons I think (I don't know all these things lol) but when I had the pan off I noticed burnt oil on the pan really dark part on the one side and they are loose as in I can wiggle them a little not a lot but more then I would think would be ok

    You can get to it from above with a small 1/4" ratchet and a 10mm socket if you tilt the socket onto the nut from above. You can also get to it from the wheel well if you remove the splash guard blocking the crank pulley (soak the small bolts overnight or they'll snap off; there are also 2 plastic snap-in guides that should be eased out of the fender, not ripped out)

    You don't have to remove the nut completely, it's a slot in the cover, not a hole. You do have to remove the service belt tensioner to remove the timing cover (use a 6-pt box wrench, a socket won't fit).

    The crankshaft is what has the connecting rods on it, between the main bearing caps. The specifications for the side clearance of the connecting rods to the crank, i.e how much they will move sideways, is that .014" inch is the "service limit". If its looser than that I wouldnt worry much, unless it was more than say .020".
    The specs for clearance of the con rod bearing on the crankshaft (i.e. the up-down direction) is a max of .0026". With the old being cold, I dont think you should be able to feel any play in the up down direction, not on any of the four con rods. And tightening the nuts on the connecting rod caps should not make a difference. The nuts are supposed to be torqued to 26-30 ft-lbs.

    All these specs are in the Ford Escort/Tracer Service Manual for your year of car. You find them fairly cheap on ebay, and you should have one. You should also read it on those days when its too cold or to wet to work on your Escort. You cant expect to remember all you read, but it helps to know the info is in the book. If you can, get the companion manual called the Electrical and Vacuum Troubleshooting Manual (EVTM) for your year of car. It has the wiring diagrams and lots of other useful into, that is not in the Service Manual.

    Good Luck.
