A friend of mine set the crankshaft, it turns out that the key-way is on top and is the mark for the lower part. we looked in the haynes manual for the top cam-shaft's. we never had a cam-shaft alignment tool but found a scrap piece of metal that worked perfectly for the cam-shaft alignment. the timing belt is on one side of the engine and on the other side of the cam-shafts are slots where the cam-shaft alignment tool, you have a 25% chance of getting it right and we got lucky on the 1st try, thanx any way.

ford escort/ focus engine 2.0 l spi sohc 1997-2004 has been identified as an intereference engine and that means very likely valve to piston damage
( auto data timing belt information )
note-- up to 2002 year Ford has not recommended a timing belt interval for changing
Ford has however recommended a replacement every 120.000 miles using the service history as a guide
however good professional trade practice recommends every 60.000 miles ( 100.00klms) and the replacement work should include replacement of the crank and cam shaft seals and idler pulleys involved ( the biggest destroyer of belts is oil)
recommended labor time is 2 hours
if the belt has broken then head removal and valve work will add up to 5 hours to that time
If this is a zetec dohc engine,There is no bottom mark. You need to buy 2 special tools to set the timing. I is a timing pin which goes into the engine next to the crankshaft position sensor (you have to remove the plug that is there first.) Also, you need to remove the valve cover and in the back of the cams, you will see a slot. Place the bar that came with the timing plug into the slot. NOTE: your number one cylinder must be close or at TDC to do this. I used a long 1/4 drive extension in the spark plug hole to check. If you engine is timed correctly, the crankshaft will be restimng on the timing pin and the bar will lock into the rear of the cam shaft. If not, you will have to loosen the cam pulley bolts and rotate the cams until they line up. Then re-tighten. You can find more detail by searching zx2 cam timing.
Heres the real deal.. there ARE NO MARKS.. however theres notches on the back of the cam that you can use a file to hold the cams in place.. on the crank part, align the keyway to the top and centerline of the block.. Keeping in mind the exaust cam will move a lil bc it has Variable timing..
cam shaft timing marks on back of cams ,two slots ,use a flat piece of metal to align .remove no1 spark plug and drop long thin screwdriver down it to bring piston just below tdc,then align cams so both cams are on the rock (valves closed) with knob on back cam aligning with pick up sensor left side between lobes.then bring piston up to tdc and fit belt.turn engine over twice with socket on bottom pulley to make sure no valves clear pistons.Remember to remove flat edge from back of cams i didnt last time and bent my home made tool
are you sure you are not 180 out on crank..crank turns twice to 1 turn of cam/s..top dead center #1 cyl. w/ both valves shut-[compression stroke] is what you want to start. some require special alighnment tools to alighn upper to lower''...kev-mn.
