Question about Ford ZX2

1 Answer

I have a ford 1710 offset tractor. I have rebuilt the hydraulic pump and have trouble with the priority valve blowing seals. The factory offers two kits to remedy the problem,the first one didn't work,and the other, which was to replace and upgrade the first one doesn't fit my tractor. I have rebuilt and tried a number of remedies but the thing still blows seals, but only when I try to turn the steering wheel. The tractor has 1500 hours on it and has been trouble free for the three years I've had it.

    I just blew a seal on my priority flow valve (Ford 1710) and my three point hitch won't raise. Fluid is pouring out near the top nut.

    Sounds like you've worked on this before.

    Can you tell me if I need to take the PCV off or just lossen the nut to replace the seal?

I had this problem too. I made the upgrades like you did,
but I kept blowing seals. The solution is really simple, it
seems that if you take it to a shop they figure it out right
away. Where is all this information stored anyway?

One of the screws on the plate holding the power steering
hydraulic diverter (below the pump) needs to have a washer
between the plate and the engine. I don't remember which one
it is but I think it might be the top one. This will bring the shaft
on the priority valve (same as diverter) in line with the seat
on the pump. Without it they are not quite lined up leaving
a gap for the fluid to shoot through and blow the seal. Also,
makes it harder to get the thing together.

    I've been to the dealership and they know nothing about the alignment issue or a washer fixing it. Can you give me any more info about where the washer goes and/or how thick the washer should be. I tried to put a washer behind the diverter and it was way out of alignment then.

    Can anyone give me information on how to check the alignment of the diverter valve. I can make a shim or install washer to fix the alignment but have no idea of how to check it to see what it needs or if I've added enough or too much.???

I have a 1983 Ford ranger with a 2.3 4 cylinder, yesterday, after replacing a lot of parts, it finally was running great--no miss or rough idle. Until I revved up the engine. Then it started running...

Hello, If this is a push rod engine I had an identical problem with an engine in my 1988-1989 Jeep Wagoneer. It was a Buick V-8 and behaved exactly like your Ford engine.

On my engine it was weak valve springs. You could take your thumb and push on the valve spring while the engine idled and the engine would miss out. Turn it off and start it up and it would idle smoothly, rev it up and let off the gas and it would miss out and shake. You could also have hydraulic lifters (check your model) and they could behave like this. At idle the lifters would pump up, but the lifters may not refill fast enough to work the valves smoothly.

If you have hydraulic lifters they must be centered in their travel to pump correctly. Even if you have solid lifters the valve adjustment can affect engine performance.

Loss of power idle flucuates clicking noise under hood also sounds like exhaust leak while driving on 96 ford escort was told have low compression in #1 and bad valve

I can tell you some things about this and what you decide to do about it is up to you.

Here is what can happen. The valve depends on the valve spring to close the valve. If there is a leaking oil stem seal, the oil can try to run into the cylinder. As it does this, the valve starts sticking as the valve stem gunks up. The valve spring can also be weak or broken and fail to close the valve.

You can change the valve spring and the oil seal on the stem on some motors by placing the cam where the valve is closed. Then using an adapter, force air into the problem cylinder(at the sparkplug hole) and the air pressure will keep the valve from falling into the engine. You then use a valve spring compressor and swap the springs and replace the stem seal.

On some motors, the cam is on top and in the way. Other motors use the overhead cam to press a rocker arm with the valve offset and accessible. The pushrod was eliminated and even lifters were eliminated. You can get loaner tools at Autozone, Advance, or Oreilys.

Another option is to have your head sent out and rebuilt or go to for Salvaged heads with shipment to your door and all the contact info you need to get the part.

If you remove the head you will need new head bolts as the old ones stretch. Of course a Torque wrench is highly recommended as the 4 cylinder heads were subject to bad head gaskets.

You should take out the number 1 plug and look at how it is burning. You may have a water leak causing the valve to fail. The clicking noise can be the valve failing to return to its base. Hydraulic lifters can collapse too. But your noise is the extra space in the valve train causd by a sticking valve, bad lifter, or broken spring.

There are some Paperback books with pictures to do this job. You can see if you fell comfortable about trying to fix it yourself.

I have a ford xe 351v8 it blows lots of black smoke

Black smoke tells me your piston rings are worn. Also the fumes you have explained tells me the valve seals are worn and leaking oil as well
The leaking valve seals and pistion rings will expell the fumes out through the exhaust. If you check your oil level every 50 miles and the oil level is down a half quart or more serious engine wear has occured and needs to be rebuilt soon

Ford escort when strts blows blue smoke

Most generally when an engine smokes on start up it is a sign of worn valve guide seals.If this engine has over 150,000 miles on it and/or it has ever been overheated it is very possible that the valve guides themselves may have escessive clearance and are the cause of the valve seal leak.These vehicles have a history of cylinder head problems and if this is determined to be the problem, the only true repair for it is to have the cylinder head rebuilt or replaced.This process can cost upwards of $900.00 to $1,200.00 to do so you might just put up with the problem until it become unbareable. Always be sure to keep the engine oil full and changed on regular interval of 3 mos/ 3,000 miles and use Lucas oil stabilizer to help minimize the oil useage .
