Misfiring taurus ticking sound from valve cover.took cover off and found 1 of the push rod had fallin off so i put it back on.put everything back togather.now the car is misfiring at idle....

Pull intake off pull off valve covers,loosin rocker arm bolts and remove ,, pull push rods out, after you have the push rods out you can pull the lifters out,,,,,,i suggest taking to a mechanic shop,,, if all you have is a ticking sound try this,,, buy a can of chemtol spray,,,chemtol only,,, with the little red straw for spraying,,,remove valve cover,,try to see if you can hear which lift or lifts is ticking,,,turn off car,,,loosen not remove that rocker arm,,,slid to the side,,count your turns,,,move rocker to the side,,, take chemtol spray and insert little spray straw and spray it down the hole in the center of the push rod ,, it will clean the lifter of the debris that is not letting it prime up,, repeat if nessary,, it works,,, see YOU TUBE,,, dirty oil causes this,,, put in clean oil and some lucas oil treatment to help prevent in future,,, keep oil changed ,,if it starts ticking again change oil and add more lucas,,, it might fix itself

It could be that the valve clearances need doing, if that doesn't fix it then put a oil pressure guage on it and check the pressure,

Sounds like you maybe broke a valve return spring?

Hey Kimberly... First... is the noise a high pitched ticking or a lower pitched knocking or clunking?? ...this is IMPORTANT>>
Reply to me on here..please...

Doesn't the OHV engine have hydraulic lifters? If so there is no adjustment.

hold up rod bearings were did you get that?lets take it from the top.camshaft lobs move lifters on rotation,which lifters move push rods,push rods push valves up and down,which other side of valves push up and down valve stems,which open and close exhaust and intake stems.ok now were clear on that to see your push rods.take off your valve covers on side with tick.1.check for valve loosness.need a feeler gauge for this and specs for you truck to do this.because ticking is mostly associated with valve loosness or to tight.2.if rod is bad loosin valves but not off and inspect the rods for bends.on a flat surface.replace if bend.also make sure they to go back in same place.and repeat step 1.finally noise continues need to take in and checked possible internal damage.

Did you get the valves reset after you changed the push rod? Check that the clearances are good.

assuming it is fuel injected you could have a computer issue.

Check the spark wire for the #1 plug. I had one get burned by the header, I would check it for burns or cuts. Sorry I couldnt help more.

Stuck Valve.Or just about ready to stick.
