    I picked up this super clean 2001 escort se model.
    It has 103,299 original miles. This thing is like a time capsule its so nice.
    I thought it would of had grey interior like many i have bought or seen at the wrecking yard. This one has the tan , goldish interior. Im glad its in good shape cause they are harder to find.
    Well i pulled the plugs and number 4 had a smashed spark plug electrode.
    I just had to see where i was at damage wise. Well its not good, the cylinder liner is punched through.
    This happened to me with the first 3rd gen escort i ever bought.
    I had that block sleeved but its more expensive than to just get another good block at the yard. So im going to go that route this time.
    I wanted to do a zetec swap but this car supposedly has working a/c so im just gonna fix this split port. I will hold off for the wagon zetech i wanna do.

    That is really clean. Consider yourself lucky you can find Escorts without rust. :)

    Hey, that looks like the SPI engine I picked up recently!

    I guess that's what happens when people keep running them after a valve seat drops.

    Well then you just needed to keep driving the other two until they too blew holes in the cylinders!

    I was at the wrecking yard today looking for some seats for my friends honda.
    Low and behold i found a rebuilt short block laying on the ground for my white escort.
    They must of needed the head for their split port.
    I didnt have the 190 the wrecking yard wanted for the short block on me because im buying the corolla today.
    :(
    Well i managed to stuff it in the trunk of a honda with help from a random person looking for parts.
    My plan is to go back and get it. The only thing i didnt care for was it was bored .050 over.
    I cracked a connecting rod loose and the bearings are fresh and new.
    Let me know your thoughts on the .050 overbore??
    I do kbow those cylinder liners are super thin thats what has me taking 2nd thoughts.

    I assume that the overbore is actually 0.50mm, or 0.020".
    Overbores are fine for anything but heavily turbocharged engines. It's unlikely a manufacturer would make pistons that resulted in an unusable engine.

    What are we looking at here? The top of a piston?
    Holy F! And then the hole in the cylinder? Wuh?
    Seriously? I thought these engines were mostly indestructible with the
    exception of the timing belts?

    What hapoens is the valve seat breaks into a bunch of pieces. (Sometimes large) It beats the hell out of the pistion and ends up fracturing it.
    If ran to long it will separate the wrist pin from the piston, the rod will bend slightly and the wrist pin punches a hole in the cylinder liner.
    In the most extreme cases ive seen the rod completely go through the block or even bust out of the oil pan.
    Two escorts i was able to rebuild with new pistons and just hone the cylinders . But those cars were shut down quickly and didnt get a chance to go full captain insano on the inside of the block.

    My block can be saved with a ductle iron sleeve.
    However it is a bit expensive to do , avout $180.
    With so many in the salvage yard i can get a bare block for about $100 so i will most likely go that route.

    When rebuilding the engine. Make sure to have the hardened valve seats installed on the intake valves. Then the split port will never suffer this kind of carnage again.

    The dropped seat damage can't be helped if the stock seats fail.

    The hole in the cylinder syndrome is completely avoidable by not running an engine with a dropped valve seat until it self-destructs.
