thats when timing belt breaks and valves are able to hit pistons = dead motor =
big $$$$$$$


i currently have a volvo with the b 230 motor which is not, so timing belt
breaks, you tow it home put on new belt and you are back in business.

Yes, the US engine is an "interference" engine, as you call it. After
owning a 1990 Escort for 6 years, I soon learned that the timing belt should
be changed at least every 100000kms. The belts in my engine broke twice;
the first time I was lucky. It snapped on a cold morning of trying to start
the car in my driveway. This was at 111000kms, no damage was done, and I
managed to change the belt myself. The second time it broke, I was driving
into town and I noticed the engine was pinging. I stopped at a local parts
store and put a 500ml can of Valve Cleaner/Treatment to see if it would
help. I then proceeded to the city, 55km drive on the highway, where my
next stop was at a mall. When I came back out to go home, I discovered the
same symptons as the morning the timing belt had broke. I towed the car
home, found that indeed the belt had broke, changed it, and after starting
the car, discovered that the valve tap was still there. I chewed up 2 new
timing belts before I realized a valve was bent. This happened at
274000kms, and was my own fault, knowing that the belt needed to be changed
and neglected to do it. Shame really, that engine ran very well, despite
its high kms and the fact it would have needed a head gasket if it had
lived.

If taken care of, I can honestly say these engines would last a long time.
I know that if I had changed that second timing belt and changed the head
gasket, that engine would have ran up to 350-400000kms.

Regards
Sharky

BTW, the engine I pulled from the $200 Escort I bought for parts and DROVE
HOME had 243000kms and ran even better than the original.

The 1.9l engine is not an interference engine.The timing belt on my 95 escort(
1.9 l, same engine) broke at 120km/hr without any damage( 127,000 k on the
engine).This is why there is no mention of the timing belt on the maintenance
schedule for that engine.The 1.8 l twin cam is an interference engine .This
conflicts with other replies, so if you are in doubt check with a few ford
dealerships.Ask them, what is the result of a timing belt failure.

Did you read my post? Apparently not. The timing belt on my 1990 Escort
lost a tooth and jumped 2 teeth on the gear after driving 60 kms down the
highway. The engine was pinging like hell. Once I got where I was going,
the belt snapped off.

When I towed the car back home and replaced the belt, the car would only run
for about 30-45 seconds and then stall. It would turn over but not start.
When I checked the new belt, the teeth had been torn off. I rechecked
everything, TDC, timing marks on the pulleys, spark, fuel etc. Put on a
second belt, same thing. When it ran this time, I could hear the valve
tapping non-stop and after 45 seconds, stalled again and would not start.
With both new belts, while turning the engine over, it felt as though there
was a certain point in the starting cycle where the engine was trying to
hold back, or gum up. I could tell something was wrong, but wasn't sure
what it was.

Everyone I asked told me I bent a valve, or even two valves from driving
down the highway with the timing out. Lucky for me, I found a cheap
replacement. So from reading this above, that would tell me that this
engine is an interference engine.

Sharky

BTW, I'm not trying to start an argument. Based on the original posters'
definition of "interference", this IS what happened to my 1.9L engine.

hmmm, are you sure yours was the 1,9 motor???

i once heard the 1,8 is interference and the 1,9 is not.

so thats why i am so curious, yours having been a 1990 i would assume it was
the 1,8. do you remember what the displacement on yours was??

hmm, yours is a 95
since you were driving and it broke and no damage then yours is definetely not
interfering no question.

maybe they changed the valvelift or something on the 94 and up model so that a
broken belt means no more dead engine.

i will check with the ford dealer to make sure. so far i have yet to get me the
car, but this is kinda important to me.

thanks much

Well, I have looked at the specs for my car in two places... in the link on
this page and in a repair manual... I wonder which is right? Now this idea
is bouncing around my head that I could sustain *shudder* heavy damage if my
belt breaks. I WAS going to let it go for a while and if it broke... eh...
but now?

Hope it's not Gates automotive just trying to sell more belts :-)

I had this looked up in the Helms and the '93 Scort 1.9 is not an
interference... looked at it with my own eyeballs. Could the motor have
changed for the '94?

Sorry if I added to the confusion, but just had to toss my 2 cents...

Cheers!

The only engines that are "interference" are in the cars from 1990 and
under. All the newer engines from 1991 + up are not interference. If you
have read my post earlier, you will know what I went through when my belt
broke twice on my own car, which was a 1990.

From experience, the pre 1990 1.9 liter Escort engines are NON-interference
engines. While putting on a new timing belt I had to turn over the engine to
get it to TDC. There was no internal interference, and I'm still driving the
car.

Good luck

Go to this link. Read my post. If taken care of and the timing belt is
changed every 100,000kms, you will likely never have any problems at all.
But, like what happened to me, the timing belt snapped after a long drive
down the highway (and needed to be changed, I was young and careless). In
the process of driving the car with the timing 2 or three notches ahead, the
piston was hitting the valve. It bent the valve to the point where the car
would only run for 25-30 seconds and stall, when it tore the teeth off the
new belt.

Yes, when you install the new belt, there will not be any interference.
There shouldn't be interference, unless what I just described happened
before you changed the timing belt. The interference will only happen once
the damage is done (valve is bent), meaning if the car is taken care of and
the belt is changed periodically, you have no worries.

All CVH Escort engines are NON-interference, that includes early 1.6,
ALL 1.9L, and 2.0L split port engines. 1.8L Escort GT engines are built
by Mazda and are definitely interference engines. And just to cover
everything, 2.0L Zetec engines are also Non-interference.

I've had the timing belt off by 2 teeth before, and the car ran ok, but
sputtered a little. It's how I knew the timing was off. When I checked, it
was 2 teeth off. When I put it back right, the car was fine.

I don't know if there's a difference between European and American Escorts,
but I am certain that my Escorts were all non-interference. 2 of my Escorts
had 1.6l and 2 of them had 1.9l. Both type of engines I've had to change the
timing belt, and both engines were non-interference.

I even had the water pump seize up on me on my Escort with a 1.6l. It tore
the teeth off the belt and would only run when the belt happened to slip
close enough to correct to allow the engine to start. I replaced the pump
and the belt and drove it for another 7000 miles or so before I sold it. Ran
just fine.

I don't doubt that you had the trouble that you described. But I've owned 4
Escorts and got to know each of them pretty well.

Mazda built 1.8L engines are *not* interference. My belt snapped in my 93'
while doing 70 down the highway. I had no idea anything had happened other
than the tach dropped to zero, and the check engine light came one. No
noises, loud bangs or clunks. Oil pressure and battery light didn't even
come in since the bottom end was still spinning at 3500 RPM. Slapped a new
belt on it and it ran just like new.

Did you pull the head and look that the valves? How do you know it
wasn't the lifters, valve springs, or cam? What I've observed is that
most people (myself included at one point) just assume that all escort
engines are interference engines, so I'm not surprised that this is
what everyone told you. I thought my top end was shot when my water
pump seized on my 90 1.9 EFI HO, but wasn't the case. I have observed
on an '85 1.6(?) that if you let the oil go (whoops!) you will get a
valve tap. <G>! A clogged oil port can do that, too, right?

Sorry about that, affter going back over the books I noticed that the
clearance is tight, but non-interfereing, similar to Taurus SHO, in that
after too many miles, valve wear under the spring can cause the valve to
dip into the cylinder about .010" thus becoming interference, the 1.8L
behaves the same. There are shims made to go under the springs on both
engines to correct this wear.

hmmm, i just looked at my volvo in their listings, they have it down as an
interference when in fact it is not.

so much for that i guess.

so since i have not bought my ford escort i will call the dealer today and find
out for sure.

It's always a good policy to have the timing belt & water pump changed
when you buy a used Escort - no matter what year or engine. You never
know for sure how long ago it's been done, if ever, unless the seller
has a shop invoice to prove it. Might seem like overkill on the
surface, but why risk a Sunday afternoon breakdown in West Dumptruck,
Tennessee?

Our '92 Escort LXE (1.8L DOHC) was purchased in '94 with 37,000 miles
on it. I had the dealer do the timing belt & water pump as a condition
of sale, and the belt has been changed every 45 - 50,000 miles. The
water pump every 90 - 100,000. Eight years and 140,000 miles later,
it's still running like a champ. The engine compression is still
within limits and acceleration will still push you back into your
seat. Overall, I think it's the best $4,500 I've ever invested in a
car.

We do, however, have another problem with it, but I'll put that into
another post so as not to mix it with this thread.
