Question about 1991 Ford Escort

1 Answer

I changed the lifters and rocker arms in my 91 Ford Escort 1.9L. After changing them, I took the car out for a spin and had no problem, just a small tick so I fixed that. When installing the lifters, I rotated the cam so the lifters would "bottom out" on the bottom circle of the cam. I rotated the cam with a breaker bar never removing the timing belt and in a clockwise direction. After I got all correct, I took it out again and now it will cut out and it is missing terribly! It won't go over 37 mph without dying when I step on the gas and acceleration is slow going. What is my problem?

Check the timing marks a be sure that when you turned the camshaft you do not advertently cause a belt problem. You should never rotate the engine or camshaft by the camshaft bolt when the timing belt is engaged, the lower drive pulley is smaller than the cam pulley so it become very easy to put a large torque load on the lower pulley by turning the upper one with the belt on, chances are you may have popped the belt a tooth, and the engine is no longer in time, if timing is not correct inspect the full length of the belt and replce if neccessary. Hope this helps, let me know.

If ticking sound don't go away after flushing oil change is there a need to repair engine


Ticking sound is typical of slack in the valve train. Try using a wood dowell "stethescope" and touch it to the rocker arm cover over each cylinder. If a rocker arm adjustment is too slack, you'll hear a clicking sound rather than a muted murmur. If you find the noisy lifter you will need to remove the rocker arm cover and adjust it. CAUTION NOTE - It is possible that a hydraulic lifter may have some grit in the internal valve. That would stop the lifter from functioning properly.

Motor knock sounds like rocker arms or lifters?


If your engine is knocking the sound with be at the bottom of your oil pan but if you have lifter or rocker arm problems the sound will be at the top of your engine. One other thing you said your car has 315k it might be time to change your oil pump.

The lifters make a rattling noise after start up, it gets quiet after driven a bit, how do you replace these?


when was your last oil change ? your oil could be dirty and basically used up,, change the oil and filter first ,, see if that doesn't help with the noisy lifters, I suggest having the rockers adjusted if the problem persists , this is a much cheaper fix, and its normally the rocker arm adjustment thats slowly gone bad, but to answer your question, you would have to remove the intake manifold to get to the lifters depending on which motor your vehicle has ,,

I replaced intake gaskets on my 91 it started and i didnot have the rocker arms on tight enough so i retightned them and nw it wont start how do i make shore the timming is right


year? model?engine? there no reason for the timing to be off, unless you took the distributor out? you may just have to crank it until the lifters pump up.. if the rockers are adjustable, you have to adjust them.

76 351 mod 400 has a noise that sounds like the rocker arms are loose .Are they adjustable?


Yes the are adjustable, if they are the original camshaft lifters and rockers they should be hydraulic and the adjustment is 0 valve lash.

1976 is getting back there and some wear along the line someone might have changed them, remove a valve cover and see if there is a set screw on the rocker arm if there is they have been changed to a solid set and you will have to adjust them try .006 intake and .008 exhaust.

A ticking sound comming from the lower end of the moter


mcdevito75 here, Not really a lifter as much as could be a rocker arm, check for proper oil level. No way to test without removeing the valve cover., If high mileage, it"s not worth it, once you change 1 rocker you"ll have to change them all approx $20.. each rocker arm part.

Ran perfect till i had oil change now it is missing bad untill it gets hot


When was the last time oil changed before this one. Your hydrolic lifters are losing prim. Causes the rocker arms play. So valves are not opening and closing right. eather higher vis oil like 20w 50 or fix the lifters

Need to know if I can adjust the valves on 86 Ford Escort


normally they are not adjustable, look at your rocker arms, do they have a nut and screw threaded into them? if not they are not adjustable, are having trouble with lifter tapping noise? this happens to not adjustable valve engine due to lifter wear, the hydraulic lifters lose their ability to hold oil pressure so they create space instead of elimanating space, and should probably be replaced. Hope this helps, let me know
