NOTE: Electronic Ignition engine timing is entirely controlled by the PCM. Electronic Ignition engine timing is NOT adjustable. Do not attempt to check base timing. You will receive false readings.

john i removed the camshaft and forgot to mark the camshaft . this vehicle doesn't have anything that will keep the timing sproket in place in the camshaft. I am trying to find out what's the position the camshaft needs to be having set # XXXXX cilinder at top dead center

Customer: replied 4 years ago.
where do i get the special tool and what I really need is the position that the camshaft goes in relationship to the crankshaft because it can be done without the tool, i just need to know the timing
Expert:  john -aka eauto replied 4 years ago.
thats is the way ford specifies the tools should be available from otc, lisle snap on and ford...I know of no other way
Customer: replied 4 years ago.
please find out where the left camshaft is supposed to be positioned, anyhow i will accept the information because you did your work. the camshaft itself has some marks in some of the lobes so there has to be one of them that should be align facing upward or something. In addition can you please tell me the firing order and if I was to calibrate the lifters wich i know is not possible I will like to know which valves need to be closed at top dead center, which need to be closed at a 120degrees turn of the crankshaft, which at another 120 and which at the last 120 since that will help me find the position the camshaft is supposed to be. by the way it is only the left camshaft
Expert:  Kyle replied 4 years ago.
Hello I am a certified Ford Technician and I can tell you from experience that it is not possible to correctly time a 4.0L engine without the special tools. This is because you time the camshaft itself to the crankshaft, not in relation to the sprockets, chain or engine block markings. There is a special tool to put the Crankshaft in a precise position and at that point you use another special tool to align the camshaft. There aren't any keyways or alignment pins in the end of the camshaft to align the cam sprocket to the cam. If you loosen the cam sprocket it will spin freely on the end of the camshaft, thus making it possible to bolt the sprocket to the cam in any position. So you align the crankshaft to the camshaft with the special tools and then tighten the camshaft sprocket bolt once everything is in the correct location. If the camshaft sprocket is even slightly off and tightened in the incorrect location it will cause a running issue. I cannot recommend any timing method other than with the special tools, because it is not possible to do so, and because it could lead to internal engine damage. I suggest you try to borrow or rent the special tools from a dealership or shop that has them. I hope this answers your question sufficiently.

Thank You,

Kyle

Customer: replied 4 years ago.
john thank you very much. I know the sproket doesn't have to do anything with the timing however the camshaft does. All i am saying is that the camshafts do have marks and they are there for a reason. I understand that everything will be much better with the tool but the tool is not available for another week nobody that i know of has it. The local ford dealership doesn't have it, they just mark the timing chain were they take the old one off. Somebody out there know the timing marks of that crankshaft and if you find out i like to know, please help this is an emergency don't want to loose a good customer. If you can answer me with the information i need. don't worry i already hit accept.
Expert:  Kyle replied 4 years ago.
There aren't any marks on the crankshaft. You must use the tool that aligns the crankshaft properly. I have seen others attempt to time this engine without the special tools many times, and I have yet to see anyone succeed without any problems, or having to take it back apart and use the special tools.

Thank You,

Kyle
