well, ym escort is broken, long story, and isntaed of just describing it, i'll let it tell you personally


i got a comment on the video saying what happend, and what needs to be fixed on it

These Escorts have a problem with the #4 intake valve seat dropping out if the EGR valve sticks open. This sounds like the valve seat dropped into the cylinder. My Son has a 95 Escort wagon and we are in the process of changing the cylinder head to fix it. Note: I wouldnt let it run like that if you can avoid it, it will damage the top of the piston. Good luck, we are figuring $600-$700 in parts alone. (Head, Head Gasket, Intake Gasket, Timing Belt, Water pump, and new EGR valve.)
so is what said above true, and where can i get the parts? just head to a junk yard and start taking off heads? any write up/how to or any other owners who have been through this please chime in! i need to fixe my wagon!

definitely sounds like a valve seat. do not run it anymore! if you want to figure out which cylinder it is, pull out the plugs and look at them. one of them will probably have a smashed electrode. on the 2nd gens, it's not always cyl #4.

as for getting a replacement head, you can try the junkyard, but start with a car that was hit in the rear, it was more likely to be driving and it won't be a pain to get the stuff off as a front hit might be.

There is more to the story....

Unfortunately there is more to know. If it sucked in a broken valve seat, there isnt room between the head and the piston tops for the broken bits of the seat - and the piston may be damaged. You will know this as soon as you have the head off. If the top of the piston is marked up, there is a fair chance the piston will have been distorted in the process. The top compression ring may be stuck in its groove, and the wrist pin boss in the piston may have 'closed', making the piston tight on the wrist pin (its supposed to be a tight fit in the connection rod end, but to float with about .001" tolerance in the piston boss). I dont know of any way to learn this without taking the 'scarred' piston out.
I bought a car where it had been driven a couple of miles after the loud clatter started. Rather than deal with needing a rebuild on the head, two pistons w rings, and possibly having the con rod journals on the crankshaft being out of round, I got an entire JY engine, and did a quicky rebuild on the block, and a valve job on the head. Along with a new clutch, I hope the car will be good for another 100,000 miles.
Though the damage can start with a single inlet valve guide, the broken pieces can easily get blown back into the intake manifold (after all, the valve isnt sealing off the inlet anymore) and sucked into the other cylinders. Technical term is 'communicable failure'.

About that quote: Im not sure the EGR valve had anything to do with causing the failure. The inlet valve seats can loosen up if the engine gets overheated, and maybe they can loosen up 'just because'.

so would just getting another gnine and just swapping it in be easier? i know a shop quaoted for repairs more then what we paid for the car, and i do rmeber hearing a bad clanking before it died :(

this doesnt sound good better start taking it apart to view the carnage, i want to get this up and running as cheaply and easily as possible, seeing some of the cars on here have inspried me to do some apperance mods

The cheapest would probably be getting a JY engine, hoping it was in decent shape (which is like any other throw-of-the-dice), and putting it in yourself. They arent very difficult to remove/replace, though you do need a place to work on it for a couple of days, a hoist, and lots of paper towels.
But while the engine is sitting on the ground next to the car - it is much easier to work on than when its in the car.

i think just swapping an engine would be the best bet, i have freinds who work on cars, and access to an enigne hoist.

now i just need an engine and free time. also a write up/ how to would work too!
