Need some help: Setting timing on H22a
Ok, i searched, but i didnt find what i really need
I have a jdm h22, with skunks cams and gears. I just installed my H23 manual tensioner, everyhing went smooth except re-timing the motor.
Now the crank timing is self explanitory, the timing mark on the block and crank cog lines up. But what about the cam gears?? I've tried to set the timing for the cam gears with the timing marks pointing straight up, but i still have my doubts that they are right, because the car isnt running right at ALL. and i think i hear moving air through the intake manifold when i turn the crank which tells me that timing is WAY off. haha
So basically.
Is there a easy way to make sure the cam gears are at TDC??
Like i was reading that you can put a small punch through a service hole in the 1st bearing hole to lock it in TDC, but i dont see it. And is straight up in realation to the motor, or stragiht up in no realation to the motor right?

Yes look directly behind the cam gears. You will see a whole in the two bearing caps closest to the cam gears. Stick a screw driver or allen wrench in there and your gears are at tdc.

The H22 doesn't have them. I wish I knew why.

do you have to take the rocker cover off?
And whats up with this Not revving up problem now? it might be electrical? i just had the motor out and i put it in myself. I marked all the wiring, but the marker wore off so i just did what i remembered.
there are 2 hook ups off the fuel injectors sections, one is IACV the other is ????
Also, there is a harness near the IAT sensor, and i dont know where it goes

simple to find out if ur engine is on tdc. take #1 piston spark plug out and put a long barbq stiick in the hole and slowly turn the crank pulley counter clock wise while watching the stick go up. once you do this check if your flywheel timing mark and cam gear matches.
If the marks on the camgears and the crank are pointing straight up, your timming should be set. I dont see why your having problems. What have you done with the TDC/CKP sensor? Also are you using your balancer shafts or no?

If he just replaced the entire engine, it could be any one of a hundred things causing a problem. If there are wiring harnesses not plugged in, that would probably be a good place to start.
Im thinking its not cam/crank timming related, because if your timming were to be off and you were to crank it up, you would be replacing that head again. It has to do with something else. Like i said, check your TDC sensor and go from there.

yes they do. there is one little hole in each one of the cam holders. i'm talkin about the 1 piece holder that runs along the length of the head. u can stick a punch in those holes (1 for intake, 1 for exhaust) and then into the cam.

Is this something that's only on the earlier H22's because I can't see them anywhere.

OK, so what would be wrong with me TDC sensor?? and im sure the timing is correct, so it has to be something else.
Does anyone have a wiring harness schematic?
I'm gonna go over it more to see if i can find something, but ill check all the sensors again
BTW im not running balance shafts

oh i thought we were talking about A1's. i dont know about 97+. A1's do have them though.

I doubled checked something.
On PreludeOnline there's a thread by boxerpower where he changed the cam seal in his 98 SH. He has this picture in there.

If you look above the lobes for cylinder #2 you can see the holes that were mentioned. Plus I just looked at my soon to be installed Crower cams and they actually DO have a hole in each cam that looks like it's supposed to line up with those holes in the cam holder plate. Craziness huh?
As for the holes in the end caps, I don't know anything about those.
