    As a measure of preventive medicine - what would you recommend to prevent a dropped valve seat before it happens ?

    It's a 94 lx 1.9....

    Can the existing head be removed and fitted with better valve seats ?

    Should a later model head be used and if so which year ?

    Engine is running perfectly, just want to make sure it continues that way !

    Thanks

    Yes, the seats can be replaced.
    Best thing you can do is not to let the engine overheat. Make sure your rad fan operates the way is should, if the engine starts getting hot don't continue driving it, find the problem and fix it.

    Yep, dont let it over heat. That will help. I guess, I dunno. I've been driving Escorts now for 6-7 years and never dropped one.

    the one mine did drop in my temperature guage didnt work and i reved the crap out of it in snow one day so ya keep that cooling system in good shape and you'll probably be alright.

    i know that car was treated like crap from the day i bought it, rust in the anitfreeze, clogged heatercore, idle/vaccum leak and it sounded like crap especially nears its death sounded like a valve sapping noise or something but it was a pony so i couldnt resist

    Don't drive the car. Mine never overheated, but dropped a valve seat at 72,000 miles anyway.

    I agree (I was just kidding about not driving the car above, even though that will prevent the valve seat from dropping). About the only thing you could do is get a valve job once you get a lot of miles on the car and could use one anyway due to wear. Or just keep enough money handy in case you need to fix it after it drops. 8O

    Yeah, and I did bitch to Ford and they didn't care (sent me back a letter that was laughable).

    Is it just the intake valves that let go? Do the exhaust valves need to be replaced too?

    i know its usualy one or the other always starting at the 4th cylinder but i would buy a head from ebay since they have everything done and come with a 1 yr warranty and thats probably about the price it would cost to have it done.

    the head I bought off ebay said it had the upgraded seats so the problem wouldnt happen again.... but who knows I doubt I will ever put another 200k on the car to find out

    Crap. You guys have me convinced on getting my valve seats replaced on a fine running JY engine before I drop it in my wagon. I'm already replacing front and rear seals, pan gasket, the oil pump, the water pump, timing belt and tensioner. I'm the poster child for Murphy's law.

    it'd be alot nicer if it dropped and at least kept the top of the pistons in good shape, two of mine were all chipped but maybe that was from repeatedly trying to start it when i knew it wouldnt.

    i had a good head too, il know better if that happens again
