  • Quinn Carollo Oct 16, 2010

    checked compression. 180 on all but he one having trouble. zero on it... at this point is there any way to tell if it heads or piston? i got this car for $250.00 not running but in very great condition body paint and interior. Spent $780.00 on new head gaskets and intake gaskets(original problem) then $1500.00 having transmission rebuilt. i have check around and can get a rebuilt motor for around $1500.00. but would rather just have this one rebuilt.

Do a compression test on the engine to see if the valves are working properly. You may be able to borrow a tester from the parts store. remove the spark plugs and screw the tester into each plug hole one at a time. Crank the engine a couple revolutions nd then check the pressure on the gage. Write it down, release the pressure in the gage, and go on to the next cylinder. Any cylinder that is much lower than the rest has a valve or rings issue. If you have questions, please let me know.

    When the heads were put back, is there any chance a rocker got put in too tight? Or maybe the wrong pushrod went in there. I would take that valve cover off and make sure the valves on that cylinder can close. If thevalve clearances are good, the cause is usually a burned valve. There is only labor involved in taking the intake manifold and head off, right? Do you have the tools to do it yourself? If it's just a burned valve, you can take the head to a machine shop to have the seat squared and have them put in a new valve.
    If you're going to have someone else do the work, it's going to be at least a day's labor, maybe more.
    If it is somehow the piston or rings, it's going to be another day or two labor. You should ask your favorite shop for a quote if you're thinking of going that way.

Miss fire on #3cyl. where is #3 located


Number 3 is the 3rd plug back on the passenger side. Coils are notorious for going bad, I would recommend replacing the spark plugs, while you are there. Use Auto Lite, or Motorcraft Platinum Spark plugs only.

Engine misfiring cylinder #3


Hi there;
I have run into an issue with these engines miss-fireing on #3 before.
You may want to have you tech check the miss-fire count for #3 & #7 on his/her scanner, THe distributor cap on these engines is made so the spark for #3 crosses over the path of #7 & they sometimes mix & become one. What happens then is they may be fooled by a spark coming through the wire if on a test lead but won't send the spark to the cylinder. The spark always goes to the easieat place so when cyl.#3 is ready to fire it is easier for the spark to go to #7 & vice-versa, So you tech will see a constant miss-fire on #3 & an intermitant missfire on #7. they can ceck the cap by pulling #3 plug wire off the distributor cap while the truck is running & there will be no spark, if he puts #3 back on & pulls #7 off there will be no spark there. the computor will only set a #3 miss-fire code because that is the cylinder that miss-fires the most.
If they find that is O/K you will want to have them do a compression test. If they find the compression is conciderably lower on cylinder #3 than the rest the camshaft theory is plausable.
The next step will cost you some money but it will tell you if you have an injector issue. You will have to pay you tech about 3.0 hrs to do this & you can just have them replace the #3 injector & hope it works. But they are around $200.00 rebulit so thats alot of money to throw at a hope. You'll need to get them to swap the #3 injector with the injector from one of the other cylinders then run the engine. if the miss-fire moves to the other cylinder you know you have an injector issue.

I hope this helps, Good luck, please let me know how you make out.
Farrout!
