camshaft timing

if you did it incorrectly, you may have bent the valves. Remove the covers and inspect the gears.

Here are the camshaft timing marks and how to do the chains (below)

Roy

another question I only removed the LH timing chain so does that mean i would have bent all the valves on both camshafts reason why i only did the LH side is one of the valves was cracked and had to be replaced and the head gasket was blown

CAUTION: Failure to verify correct timing drive component alignment will result in severe engine damage.



Install the crankshaft sprockets with the timing marks out.



If timing marks in the timing chains are not evident, use a permanent-type marker to mark the crankshaft and camshaft timing marks on the LH and RH timing chains.
1 Mark any link to use as the crankshaft timing mark.
2 Starting with the crankshaft timing mark, count 29 links and mark the link.
3 Continue counting to link 42 and mark the link.



Verify that the LH camshafts are correctly positioned.



Align the LH marks on the timing chain with the marks on the camshaft and crankshaft sprockets.



Install the crankshaft damper bolt and rotate the crankshaft clockwise 120 degrees until the crankshaft keyway is in the 3 o'clock position.



Verify that the RH camshafts are correctly positioned.



Align the RH marks on the timing chain with the marks on the camshaft and crankshaft sprockets.




CAUTION: Failure to verify correct timing drive component alignment will result in severe engine damage.

Rotate the crankshaft counterclockwise 120 degrees to top dead center (TDC).

Verify the timing with the following steps.
1 There should be 12 chain links between the camshaft timing marks.
2 There should be 27 chain links between the camshaft and the crankshaft timing marks.
3 There should be 30 chain links between the camshaft and the crankshaft timing marks.

okay thank you question though how do i know when number 1 piston is at tdc do i just rotate the crankshaft until the keyway is at the 3 o clock position or can i stick a screw driver in the spark plug hole and once it pushes up that when i know which is a better way

the screw driver method is ok but look for marks on the pulley.

i believe the keyway goes straight up.

Roy

so every time I turn the crankshaft all the way around and put it at the 11 o clock position number one piston is suppose to be at tdc and than turn it to three o clock and that sets the RH camshafts to neutral rotate two more times to the 11 o clock position and this sets the LH camshafts in there neutral position. So I'm just redoing the LH timing chain since this is the only one i took off and messed up after I'm done putting that one on do I still have to rotate the crankshaft and put the RH timing chain in its neutral position before i put everything back together and start the car even though i didn't take the RH timing chain apart or touched it at all for that matter.

i would start from scratch and follow the directions. once again, the damage may already have been done. after you set the chains. you need to do a compression test to verify no issues or the heads may have to come off.

Roy

Do not install the spark plugs and manualy turn the crankshaft a few revolutions after you have everything installed. When you are sure the valves are not being bumped by the pistons, you can try cranking.

question when rotating the crankshaft I have two marks on it one is the keyway slot that the crankshaft pulley goes into and another mark that looks like a timing mark which one do i go by

For LH the keyway should be at 11 o'clock position and for RH it should be at 3 o'clock position when the cam shafts are aligned correctly.

okay i got the camshafts aligned properly but my question is for the chain i know i mark any link as the crankshaft mark and than count 29 links mark as exhaust than count to 42 mark as intake but when i go to put the chain on its doesn't match up do i go buy the keyway mark or do i go by the this other timing mark

The chain should have the links marked. Follow the marks if possible.

okay so i matched the the links that were marked to the timing marks on the camshaft. everything looks good but when i go to start to start it up i feel it wanting to catch but it doesn't go is there any vehicle theft device i need to disable or anything I missing i have spark, i have fuel, and i have compression checked them all.

If the security indicator is not flashing, there is nothing yoou need to do to disable it.

Try some starting fluid to see if it works.

if this helps any I had somebody crank the engine and out of the tail pipe was black smoke not a lot just enough to see it and it smelled like just fuel coming out

another thing i discovered is when i pulled off the air intake in the throttle body there was oil in it is this why when i go to crank the engine black smoke comes out mixed with the fuel smell

another thing i don't understand is before i did all this work to it, it would start up fine and just have a misfire in cylinder 4, after replacing headgasket, headbolts, a cracked exhaust valve, etc. it doesn't want to start and the thing is i only took off the chain to the LH I did not even touch the RH timing chain at all so wouldn't it start and run rough since the RH has cylinder number 1 which is the main one I need to start. a

First thing you need to do is to confirm you have sparks.

If sparks are available, recheck your timing chain installation.

i confirmed spark as far as timing chain installation I set the keyway at ll 0 clock rotated clockwise to three o clock to position the RH in neutral rotate the crankshaft clockwise two times to the 11 0 clock position again putting the LH chain in neutral marked crankshaft timing mark 1 counted 29 chains exhaust marked counted to 42 intake marked made sure the camshafts were pointing in the right direction the intake one was point towards the left and the exhaust was point up it looked like a 90 degree angle

when it cranks it cranks several times and than it gets stuck like it trying to get over something and than it cranks again normal and than repeats the process please help i'm going crazy

Let me know all the compression readings.

okay all get back to you

quick question i know in the beginning you said that if i installed the timing chain and camshaft incorrectly i could have bent the valves would this cause the engine to crank but not start

also any ideas why i am getting oil in the throttle body and intake manifold

I have been reading and would like to know that if i installed the pulse wheel the wrong way would this cause the crankshaft position sensor to misread the timing therefore causing my car not to start but just crank

If the velves were bent, the compression readings would tell and it can cause non starting.
Yes, the crank sensor pulser ring affects the ignition system operations.
Oil in intake could be residual oil. When removing and installing the manifolds, were they cleaned and was traces of oil there?

okay so the first battery i had in there died and so i went to go get that one charged in the mean while i had the same battery in a different car so when i went to go put that one in I cranked it for a couple secs and next thing you know it killed that battery instantly I'm thinking alternator but than again I dont think it would have killed the battery that quickly and again I would say in like 5 to 10 secs of cranking

would a bad pcm have caused this and if so how do I diagnose the pcm

5 seconds of cranking do not kill a good battery. Recheck the terminals and ground circuit connections. Ensure they are clean and secure.

If you have sparks and the injectors are pusling, the PCM should not be anything to worry about. You can't really test a PCM, mostly when all other problems had been checked and found o be good, that is when you substitute a PCM to test.

okay so i corrected all the ground connections but something happened when i was cranking the engine over it still wont start but i started seeing smoke next thing you know i go to check it and it is the negative battery cable smoking it is super hot I know this means that the resistance is high but what else could it be

Yup, it means high resistance and usually it means it is not securely bolted on.

I did securely bolt it on I tighten them all down would this be the reason why my car won't crank over as well

scratch the above reply I meant to say cranks but wont turn on

okay i hate to ask this question because i don't want to know the answer because i think it might be bad but what does it mean when you take the oil cap off have someone crank the engine and smoke comes out from it

also too the more i think about it the more I am leaning towards some of the valves got bent reason being, i checked fuel and spark both okay the only thing left is compression and something tells me that when i check cylinder 4, 5, and 6 that it is not going to be good news

You need to check the compression to be sure.

Smoke coming out of the oil cap means there are too much blowby and that can mean bad piston rings.

could the piston rings have been damaged by me incorrectly putting in the timing chain and camshafts incorrectly or that would have just bent the valves

I need timing marks diagram for a Ford Escape 2002 3.0.

l need the timing marks diagram for the vehicle listed above it has a v6 3.0 engine.
