There are no timing marks. Timing is done using special tools to hold the crank at top center and a tool to hold each camshaft in position. the cam sprockets are not pinned to the cams. there are also dummy tensioners installed to take up the slack till the tightening is done. Also there are chains at the back of the motor that can only be timed with the motor out of vehical.

SOURCE: timing chain alignment
not true. SOHC 4.0 tensioner and rails fall apart, allowing the chain to slap and do damage, or even break. book it. in order to replace rioght side cam chain and tensioner, the engine MUST BE REMOVED! if it has balance shaft chain in oil pan, there are a total of four chains in this engine.

They will not loan you the tools.....how else will they continue to rip off the average garage junkie and make lots of money?

Get Ford timing tool kit, part = otc-6488 (For about $119 USD on eBay)
4 timing chains (3 front including the optional balance shaft chain + 1 back)
2 cam guides (1 front + 1 back)
2 oil tensioners (1 front + 1 back)
1 jackshaft tensioner (1 front)
1 jackshaft guide/cassette (1 front)
1 balance shaft tensioner (1 front) (will probably be ok, so dont replace it)
1 balance shaft guide (1 front) (will probably be ok, so dont replace it)
new sprockets + bolts + gaskets etc.
new spark plugs + throttle body cleaner + lithium grease spray + oil change
of these parts (the front stuff) can be obtained as a primary timing
chain rattle noise kit Part# = 2u3e-6d256-** ab for 4*4 & bb for
The kits also have later part numbers for us$ 76 @ http://www.fordpartsonline.com
My parts order (without the balance shaft stuff) was:

$28.93 Engine, Camshaft and timing, Tensioner, TENSIONER, Explorer, Mountaineer, Upper - 4.0L SOHC - 4.0L SOHC
worth mentioning that this procedure is not enjoyable at all and
should be undertaken with at least 8 full days to completion (I recon
you could do it in half the time the second time).
It is basically on entire engine re-build with both heads off and the engine out of the vehicle.
is not possible to do the rear chain or sprocket with the engine in
the car as the flywheel needs to come off + at least 1 head, but it is
possible to do the front primary chain and or front cam chain with the
engine in the car.
will be a ford exploder and timing expert after you do this - the main
reason should be the love of your American built vehicle. Its a solid
car - except for the plastic guides!
Note: This is how i successfully did the job, but i am not a ford
mechanic and don't hold me responsible if this does not work for you.
Small Sprocket on the crank turns a larger (2 to 1 ratio) jackshaft
sprocket that is in turn connected front & back to the 2 camshafts.
Thus a 360o turn of the crank will turn both the camshafts 180o.
Firing order is 1-4 2-5 3-6, Right side numbers 1,2,3. Left Side = 4,5,6.
At TDC pistons 1 & 5 are fully raised, thus 1 is about to spark & 5 is evacuated.
engine will turn freely (no piston to valve contact) with the cams
180o out, it will even run (roughly) with 1 out 180o, any other
settings may cause major damage to the valves.
2 cam shafts come with timing markings, "yes" real timing marks that
anyone can use (even without special tools) to ensure correct timing.
The way to time it is to ensure both the off centre cam shaft slits are level/flat with the head.
the engine at TDC both the cams need to have the off centre slot in
the same position either up and level or down and level.
is super critical that both the camshafts are 100% in sink with each
other, i.e. not a few degrees off, the engine computer can compensate
for crank timing but not engineering failure.
warned the camshafts can turn easily fast & hard by themselves as a
few springs are compressed at TDC, I got my finger jammed and its
still healing + if the engine is not at TDC you may damage a valve.
heres the hard thing that you will need special tools for - if you
need to change the timing, you will need to be able to undo the cam
sprocket bolt on both cams & these are done up real tight.
is a tool that you attach that has 2 pencil thick shafts that fit into
the sprocket and prevent it from turning - then you need to put about
90Nm of force on the bolt (remember the rear one if LHT)
the $money$, its well worth getting yourself the tool kit - it will
save you hours in the long run. Search eBay for otc-6488 should be US
$119 - then sell them again for say $100.
is also a tool version of the oil tensioner in the kit that screws
right in and puts the correct amount of force on the chain + guide, to
enable you to do up the cam bolt with the chain and sprocket in the
right spot on the cam.
