    I have an 8ba flathead, I took the driver’s side head off to see what is going on inside. I believe the exhaust valves are stuck, 3 out of the 4 are open on the drivers side. I'm not sure in the position of the pistons will help figure this out or not.

    But here is some info to help you see what I did, sorry no pics yet. If you are looking at the engine from the driver’s side and the cylinders from 1-4 starting from the front of the car.

    Cylinder 1 cylinder 2 cylinder 3 cylinder 4<O:p</O:p
    Exhaust open exhaust open both closed exhaust open

    i do not have the p*** side head off but looking at the valves it just didn't look right to me, is this how the engine runs? or does it sound like something is not right in the internals of the engine?



    if this makes no sense let me know so i can better explain it or get pictures.<O:p</O:p<O:p</O:p

    So the pistons are stuck so you can't turn the motor?

    A valve, when open, should have a little side play, plus you should be able to spin it with a rag and pliers.

    more info would help; is it stuck?

    could not turn engine over by hand, when i put a breaker bar on it i was just crushing the washer, have a feeling i stripped the crank but that is a diffrent thread. also i feel like a dumb*** but i can't figure out what nuetral is, engine is in the car ****** is hooked up, so that could be part of the reason it would not turn over. took the heads off and internals look like they were put in yesterday, but the 3 vavles on the drivers side are open. didn't try to spin or jiggle vavles hit em with a wd-40 style lub, took a rubber hammer and tried to tap em down and no go.

    you can pull the intake and see if the valves are stuck or just open. i had 3 sticky intakes.

    maybe the clutch is sticking too. do the pistons move if you rock the car a little?

    on some flathead v8s, i have seen the starter teeth get jambed. Maybe someone tried to crank it?

    If it were me and I did not want to wreck stuff, I'd get the starter off to see if that was jambed, but also to be able to use the flywheel teeth to gently pry on to see if the motor will turn either direction (a little).

    if you can get it to turn, use penetrating oil on everything you can and don't force anything...just rock each way till it starts to stick, then go backwards. watch for stuck valves at this point; don't try to rotate the crank if you think valves are stuck. free up the valves first.

    tired to turn it over about a month ago put some diesel in it and let it sit. opened up the head the other day,i will try to jiggle it or spin it and see what hapens if nothing will pull the p*** side head to see whats going on, and most likely the intake. then go from there.:(

    could be a bent valve. pull the starter, other head and intake. see if motor will move. Sounds like motor is out of car. if so remove ******

    So you'll know FORD flathead V8 and V12 engines have the number ONE cylinder at the p***enger side front.
    The V8 right bank (p***enger side) is 1-2-3-4 front to back.
    The V8 left bank( driver's side) is 5-6-7-8 front to back.

    V12 follows same pattern.

    Based on what you ststed that every thing looked new its possible it broke a rod and got the cam-I suggest you take the oil pan off-Thats a fast and easy and will net some good or bad information real quick. It would be hard for a flatty to "stick" ex valves in a row--Weird things can happen though.

    did you pull the other head yet? all it takes is even just minor rust in one cyl. Sounds good so far, if it looks that good, so try not to force it.

    those cylinders look pretty rusty from your pics. also from lack of adjustale lifters its probably never been rebuilt so id say your probably due an overhaul..

    flathead's that look like that...well face it, just go thru it. fun stuff. they are not like o/h vlv engines where stuck valves are more forgiving. you have done this before right?:)

    the cylinders do not have water in them, there is none now, and not before, the cylinders are not rusted it is a mix of diesel and other **** i put in there before i pulled the head the other day and whatever junk was on top of the intake ext. when pulled. if there is any rust on it , it's surface rust that can be rubbed off with my finger and can ***ure you. like i said the pics don't do the car justice it looks way dirtier then it is in person.

    Second update: took other head off, still looks good to me, also it is not the exhuast valves that are stuck open, it is the intake valves that are open. i don't know if this changes the game at all. yes the engine is still stuck but is the intake vs. the exhuast being open point to something else that might be going on. the plan is to get the rear end lifted up, take the starter out and try to spin it over with a crow bar.
