Ok-
I think I just wanna blow off some steam- but anyone with constructive ideas- lemme know.

2 years ago- bought a 1994 2 door teal auto with aluminum wheels and spoiler in Massachusetts. It was for one of my 16.5 year olds. He does drive like a little old lady- I have my ways of knowing.

One month in- ticky ticky- and dies. I replaced motor with boneyard motor with supposedly 35K on it for $325 plus all the labor and new parts(pan gasket, timing belt, plugs, etc), and am at $850.

Last summer(one month out of warranty- again ticky ticky- only this time I THOUGHT I was SMARTER and had a shop pull the head before it exploded. I made arrangements with machine shop to clean up head, remove all 4 powdered metal valve seats, and install stainless steel seats- now that I boned up on the real issues with these things. Aftwer all- another boneyard motor would be the same soon.

Shop gets head and installs, and cleans out intake in case any junk there. Takes for road test, and DIES. Diagnosis- valve seat # 4dropped and smashed piston and roughed up wall a little. THIS IS WITH A HEAD WITH NEW SEATS!!! Shop did all repairs on their nickel- new piston and rings, clean up cylinder wall, have seat redone, etc.

Well- hear I am 10 months later and cylinder #4 is bangin away AGAIN! Starts REAL ROUGH and shakes, after a couple minutes it smooths out, so I believe its time for another piston, and another head.

This thing is NOT RUNNING HOT!

The kid is buying another car now- 1999 Cavalier fro $3800, so I have 3 choices- roll it to the boneyard, sell it as is-if I can, keep it and do a transplant myself and then either dump it or use it as a commuter(I drive 100 miles a day in a Pathfinder- 30 mpg vs 18 mpg sound great) and then pass on to my youngest in a couple years.

Car has 115K I think with 1.9(obviously), tranny good, new exhaust with flex pipe, new snows, and new front struts. Teal with grey interior.


Thanks,
Chris(Fitchburg Mass)

The valve problem is a well known design flaw, compliments of Mazda Motors Corp.

When mine went I got a Jasper rebuilt engine and it cost me about $4000.
It's guaranteed for 3 years of 75,000 miles, but it has the improved valve design so it's not likely to happen to me again anyway. Your problem is that the new head you got didn't incorporate the design fix. Once you get past that issue it should be a pretty good engine, just like the pervious generations of Escorts that could easily go 150,000 miles or more without any major problems.

The 1.9 is an all Ford Engine.

I'm really surprised that the engine dropped a custom seat. The only way I could see it doing that is if they made the OD of the seat the same size as the original valve seat which would defeat the purpose. Most commonly, the 1.9's don't start dropping seats until they overheat.

Sounds to me there is some thing up with the cooling system. Just for the heck of it, if you get it repaired again invest $120 for a brand new radiator and make sure the ECT sesnor/Fan are working properly. I have 3 Escorts, none of them have had a problem with valve seats dropping.

I would look into just swapping to the newer 2.0 SPI motor, there about the same price as the 1.9 and are 99% of a direct swap.

Ya know-

I was looking at the article earlier on going to the 2.0. If the reliability is much better- I am all for it.

As for the radiator- I have never seen the thing run hot- its always at the bottom end of normal(or was) :roll:

I know just how you feel. My 1.9 dropped a seat on cyl #2. I agree with the others as far as a possible coolant blockage or the design flaw with the head as both are possibilities. Since it sounds like the same problem happened to both motors, it leads me to believe that you may have a cylinder running really lean which would also help contribute to dropping a seat perhaps. Check those injectors.

On a side note, as an autmotive machinist I have seen heads for the 1.9 run for a long while, however, if the head has a crack around the valve seat it can cause the seat to fail/drop. Also consider that you have two dissimilar metals in that head from the factory, aluminum and hardened seats to take the abuse. The two metals expand at different rates but usually nothing happens.

As has been said before in this post, the machine shop may have used the same OD diameter. Normally they machine the old seat out and cut a hair wider and install the proper OD valve seat (which is slightly bigger than the hole they cut. Then the new seat it driven in with sleave retainer. It should not fail after that.

I say run it and watch it.

It's made in USA, but designed in Japan my Mazda, just like that crappy ignition switch and crappy dash vent piece that rattles against the windshoeld. You only see these things in Mazdas and 1991 -1996 Ford Escorts and Ford Probes. I could also list a few other Mazda better ideas that suck. Valve problem is a design problem, not a manufacturing problem. Previous and subsequent versions of this car were designed by Ford and didn't have the valve problems (and stupid rattling dash piece either).

And mine has never overheated and I still have that problem.

Do you also blame Ford for the crappy Mazda brakes on 1991-1996 Escorts? Just take a trip to the junkyard and compare verious years Escorts to Mazdas and you will also notice that the brakes are definately a Mazda design. Brake parts ate made in USA (except master cylinder), but the underpowered brakes design are compliments of Mazda.

1.8 = BP, Mazda.
1.9 is CVH, designed and built completely by Ford. It's been around since the late seventies, long before the Escort or Ford had any relations with Mazda. (In terms of Escorts, anyways.) In fact, the Escort used no Mazda parts until the second gen came out in 1991. Since the LX model still uses the same engine block and design as the previous 'scorts, it is not Mazda. The 1.6 in the English Escort is also CVH, as are the turbo escorts, and the third gen 2.0 SPI's, along with the 2.0 Zetecs in the Focus and ZX2. They are not Mazda. The chassis, yes, that's Mazda. The 2nd Gen Escort is a Mazda with a Ford engine and tranny. Other than that, I dunno.

Hi

I had the same thing happen to my 94 Teal green with grey interior Escort , also bought in Massachusetts ! Car is just bad luck, I think :( .

Anyway, I had the head rebuilt, replaced piston, crankshaft, bearings,oil pump, timing belt, everything but the kitchen sink.

I know a guy at work who has several Escorts and he thinks they are awesome - his have over 200,000 miles on them . I bought mine with 47,000 miles on it and it ran like a charm - for 40 whole days - then the valve seat dropped .

I think I made a mistake fixing it but the low mileage made me do it .
I ended up buying a 2003 Elantra and my 17 year old will drive the Escort - if there are any more problems, I am nto spending good money on top of bad .

I feel your pain and frustration, believe me !
