Hi I have an 95 H22a civic.

I have taken my cam gears off to put my back cover on.
but failed to mark anything really well.

now I have double checked the cam TDC, crank TDC and oil pump mark.

but No go...the car cranks but will not start...Did I miss somthing? ~~I am using skunk2 adjustable cams~~

Was it at TDC on the compression stroke when you took the gears off? You could have set it up TDC on the exhaust stroke. Put it at TDC and double check that intake and exhaust valves are closed and the distributor rotor is pointed to the no.1 terminal on the cap

ya I've been tryin to figure that out but Im not catching on..

I haven't checked where the rotor is pointed on the distributer

I did put a screw through the hole of the cam holder down into the cam hole (too line up the cams at TDC I believe...?)

crank pulley is at TDC...also oil pump is lined up...then I try starting


Somthing I don't understand is when cam gears are at tdc and crank. I spin the crank 360 full circle with the ratchet and peek at the cam gears they are no longer at TDC...WHY unless the cam gear and crank gear are not the same size?

I did find this thread about sticking a screw driver in the spark plug hole to find tdc and compression stroke and exhaust stroke. But I still don't know How to find compression TDC and exhaust TDC~~~~~~~~~~~~~~~

Put the engine to TDC using the mark on the flywheel through the sight hole on the trans, check to see if your cams are lined up. If the cams are not lined up your on the exhaust stroke, rotate the engine one more revolution and line up the mark on the flywheel and check your cams again. If the cam and crank marks line up take off the distributor cap and see which cylinder the rotor is pointed to, it should be pointed at the terminal for cylinder no.1. If you rotate the engine putting the mark on the flywheel to TDC and your cams dont line up you did something wrong and need to start over.

nub

The crank will rotate twice for every one rotation of the cam

As far as checking if your on the comp. or exh. stroke they make a little wistle that screws into the spark plug hole and as you rotate the engine onto the comp. stroke it forces air out of the cylinder through the wistle so you know your on the comp. stroke. Personally I would pull the valve cover so I can see the position of the cams in relation to the rockers. If the rockers are on the cam base circles(valves closed) on the intake and exhaust side youre on the comp. stroke.

great Thx nubs Im gonna check it out right now

and I did stick a 2 foot piece of 1/4 copper down the piston hole to find tdc
I set crank at tdc and cams at tdc and #1 piston was at highest stroke on top..maybe thats not what you are getting at but I will walk through your steps and be back a a bit.(have to check flywheel tdc)

butter99

OK
1- cam gear arrow up
2- camshafts at TDC according to the method by putting punches in the holes of the cams to line them up
3- flywheel lined up (flywheel lined up even after full 360 revolution)
4- piston #1 at TDC highest stroke
5- distributor rotor is near the edge but it is touching #1

this is how its been since yesterday

What did I do wrong possibly?

If it was set to tdc in the wrong stroke then the white mark on the fly wheel would be 180 off and not line up. If you set everything according to the service manual then it "should start". Is the pump priming and everything hooked up right, grounds too? Thanks for those pics you posted, i saved them lol

butter99

hey hatch

ya my service manual is confusing me a little
It does talk about turning the crank and checking..turning checking..

but if all is TDC and number 1 piston is at top then isnt that what I want?

or am I forgetting somthin?

and ya i got it from manualnguide.com ~~ search 93 prelude service manual ~~ choose download pdf ~~ poof~~probably one of many places.

1. Take your timing best off the cam gears. Then follow this diagram.


2. Dont stick a pin or punch in the top of the cams cause that never really works unless u have the perfect sized punch in there.

3. On the diagram, if you notice the pic on the top right, it shows that there are 2 other timing marks on the cam gears, make sure these are lined up with the head. As long as they are lined up straight across, with the head, then you are good. Put the timing belt on.

4. Put the tensioner on and spin the crank like 6 times so the cams do a full rotation 3 times... Stop when you are at TDC. Check the flywheel to make sure it is at TDC and then look at the cam gears and see if they are still lined up with the head all the way across.

It is ok if they are off by half a tooth or so but not a whole tooth.

Good luck!

1- ok its possible I may be off by 1 tooth possible 2 because of the poor alignment of the cams but I figured it would at least start and run unpleasant..

2- I have skunk2 adjustable cam gears so no lines or arrows(but there is one line on the intake cam gear, dono what its for.)

3- yes I was trying all kinds of stuff trying to fit somthing to align the cams. I finally just eye balled it and then marked the gear with white out. so it could be off 1 tooth

4- I've noticed my cam gears..one is more positive and the other is more negative but just barely ..Possible enough to be one tooth off

5- my valve cover is stuck.. the stud is turning and nut..somthing Wierd so I cant take it off at the moment..

anyways i know this is kinda long but I really would like to figure it out doh
thx. I'll be in the garage and be back in a bit

butter99

OK correction : timing was not correct duh.
So the car starts but sounds kinda rough so I checked out the engine.

and the timing belt is walking out and riding the bottom cover.. UGH

-I have tightened the adjusting nut on the tensioner (not to spec)
I will take the bottom cover off and see what I find now..

Any idea why my timing belt would rub the cover since I have taken it off?

if you are running a tooth off it will run on a honda computer but no aftermarket computer i learned that the hard way running aem i ran in to the same problem you did line the to marks up on the cam gears dont worry about the arrows on the cam gears sometime looks can be deceaving make sure that your crank is lined up with the mark just above the flywheel it is kind of hard to see the hard part comes when you put the tentioner on because the cam gears will slip out so you will have to compensate lining up the cam gears just a little until its perfect i had to do mine 3 times till i finally got it hope this helps

butter99

Ya thx

I finally did get the timing perfect, but now I am trying to tighten my crank pulley bolt so I can be done. Then I can double check everything again and maybe adjust the cams accordingly.
