1.9 'Scort owners, read this

When the battery is low on the 1.9 SEFI motors, the coilpack doesn't send as much fire to the sparkplugs. and you also loose pressure on all the electricals when you disconnect the battery. Every time you have to disconnect the battery, you should turn the Key on and off a couple of times to let the electricals catch back up, like the fuel pump, etc.

Fire to the sparkplugs?

Pressure as in like, oh, hydraulic?

Catch back up? Last I heard electricity traveled at the speed of light.

You must think we here on this forum are all idiots. And quit saying stuff like this junk because there are others trying to learn right.

Alright, knock what I just wrote but let me give you some advice from someone that has been woring around car batteries since he was 4 years old(myself) the lower your battery's charge, the less amps the thing puts off giving it a lower charge to the rest of the electrical. don't matter if the damn electric moves at the speed of light if it only has the amps to go through half your car. don't knock me if you don't know a damn thing about how electricity works. that's why you lights get dimm when the batteries die down, thats why the ding when you open the door becomes a bung, thats why the radio blacks out or makes a hissing noise instead of music, thats why a car that normally turns over twice to start will not start no matter how many times you turn it over! don't feed me this Electricity moves at the speed of light crap! You put a steel bar and arc a full charged battery, then arc a dead battery then tell me what you think about how electricity works. E-mail me the results of your little test Mr. Ben Franklin!!!!

1 more thing, as I wrote before. when the battery looses power, the spark plaugs will not fire(spark) right. now, when I said loose pressure on the electricals, I meant that the gas will run back down into the tank, cause there is only pressure on the fuel pump when there is electricity going to it, sorry if I'm not so clear the first time, but I forget that everyone didn't grow up around Mechanics and Electricians like me. I forget that not everyone scored a 75% on the electricians test when they were in the 10th grade. And last but not least, I have owned my car for 10 years, and helped my dad fix just about every part that can go bad in 10 years and 300,064 miles. I know a little about what I'm talking about. If I come across a problem with my `92 `Scort Wagon LX 1.9 SEFI, I have 2 Chiltons, and a Haynes as a reference. Don't knock what I say unless you can do better than that

There is no " pressure on the fuel pump". The fuel pump uses
electricty to generate pressure to the fuel regulator in the
fuel rail. Since your 1.9 does not suffer from the dropped
valve seat issue why even post in this thread anyway??

You got me on the Escort experience part but I have a little over ten years of heavy jet aircraft knowlage and it comes real handy working on cars. As for a 75% on a test? So what, I scored a 92% to obtain my license and 91% in aptitude testing. So there big talker. So unless you want to debate Ohm's law, hydraulic theory, pressure differentials, or why it's impossible to acheive 100% combustion efficiency I suggest you bow out here.

Back to related content:
I am still researching about '91 to '93 not dropping vlave seats. A couple more machine shops I talked to say they haven't noticed. The casting #'s are the same what I have found so far so I think that would eliminate any material changes.Part #'s that are installed into the head haven't varied enough to be significant. So thus far I haven't found evidence.

It may be that only under certian conditions the seat dislodges.
On my vehicle I ran it for a few years with a paritially clogged
radiator. The car never actullay never overheated but ran
warm. I replaced the rad. about 12-14 months ago, the car
ran a LOT cooler, probably should have done it sooner! The
#4 cylinder gets the coolant just as it's about to leave the
block, that also might be a factor. There was also an issue
with the MAF sensor on these cars, ford issued a TSB about
it, it seems the MAF would give an errant reading to the
computer and it would lean out the mixture and make these
motors ping quite a bit. When this happens combustion temps
get REAL high and oh-oh mr. valve seat doesn't like this either.
I used to run mid-grade to stop mine from pinging....

[92EscrtPmp]

Running Midgrade always helped on any of my cars when they started to knock. Now, about the valve seat dropping. The only thing that the mechanic I grew up with could think of is the Lifter on the #4 Cylinder is put under a heavy load, and the springs breaking causing it to rattle loose til it finally drops. now, finding the heavy load that caused it is a different matter. Maybe you got something with the MAF sensor, or the clogged radiator. But I can tell you that the radiator was clogged on mine when the head warped, but the valve seat never droped on mine. Then again, every time we replaced the Valve cover gasket, we made sure all the lifters were Torqued right(2or 3 times). That is something Us scort owners are just gonna have to keep a eye on til we can come together and find the root of the problem.

Here is something for the 1.9 Scort owners read this.

Did you know that My 92 Wagon Key will start any 92-96 Scort? pretty kewl, and only Mechanics are supposed to know that. It won't open the door, but the key turns right over like it's in my Ignition. So 92-96 Scort owners beware. if there is someone out there looking to upgrade, all he has to do is look for a unlocked Scort to take. Thought you would like to know. BTW, don't think that changing the ignition will help, my ignition was changed too, and my friends scort key starts mine!

[butch100]

The valve springs and lifters were all fine in my motor. The valve
seat is NOT connected to the spring in any way. A valve seat is
a peice of hardend metal that resides were the valve comes to
rest on the head. Ford could have prevented the whole problem
by useing a stainless steel seat to begin with. That is what machine
shops are installing when they repair the head.

I have a 93 escort 1.9l with 138,000. Although I did not drop a valve seat I am replacing a cracked head. I am getting a rebuilt head with cam, is this something I will have to worry about in another 130,000 miles

[Frunobulax]

I'm hoping to not have any engine problems (other than the necessary timing belt replacements) on my '91 LX until I reach at least 400,000 miles. Only 38K to go! <fingers crossed>
