Problems with my new motor.

Well, like I have said, its in, and it starts, barely. Something is wrong with the timing, tdc, something. That I am pretty sure of. I have to have the cam gear adjust to almost 14 degrees advanced (#7 hash mark) for it to even start. Then, it sounds really, wrong. It just doesnt sound like it should. If I try any other setting on the cam gear, it just cranks and cranks, but doesnt fire up. What I was wondering, is does anybody know how the AEM cam gears work? There are 4 lines around the edge of the gear, and one has a little circle on it. This is what I assume is TDC right? Here is a pic:

So, that should be just a tad past tdc right?

Anybody have any ideas? I am only throwing one code, which is a water temp sensor. I highly doubt that is the problem. I just need to swap out the sensor.

yea the line that goes all the way up with the circle should be TDC.

Thats what i thought. So everything was alligned to TDC.

I don't know though 14 degrees sounds like a lot..:D

well, ami said to take off the belt, put on my stock gear, and reset everything to tdc, and try again. So, that will be tomorrows adventure.

yea thats what me and ami talked about. You should do that to find true TDC. and then switch them out

when it was time to do mine it went on 3 times and got results like kris got all 3 times. stuck the stock cam gear on and got it all back tdc then stuck the aem on matching teeth to teeth.

i guess if try, try, try again doesn't work...start over is the moral of the story i learned?!?!?

Well, I put the stock cam gear on, and reset everything to tdc. That problem seems to be corrected. However, I am only firing off the #1 and #4 cylinder. 2 and 3 are doing nothing. But there is spark going through the wires...

what do you mean.......only half is working:confused:

this one was beyond me. asked jer. he *thinks* he knows. when you took it apart and "reset" it all, did you take off the dizzy and put the rotor up & check the camshaft lobes... in so many words "reset" that side of things as well? your whole engine is one big ass firing order. that part of the order might still be off ;)

ps. i ended up answering my own question :) its ITR design. that little word makes all the difference...they fit, ITR does not!

Yep, I pulled the dizzy to make sure that was set right, and it is. I figured maybe the injectors were clogged/broke. So I pulled the #2 and #3 and replaced them, still the same thing. I dont have a ohm reader here, so I cannot test the injector plugs/wires. Nor do I have a compresiion tester here as well.

If the head gasket did not seal right, (no compression in those chambers) could that cause it possibly? But if so, wouldnt I have coolant in my oil, etc..

Also, what if the rings are not sealing right, would that cause this problem as well?

But the exhaust is coming out reletivly clean. But there is lots of condensation however.

if anything I would say that your rings did not seal right. You would see something if it were to be the headgasket. Is there any white smoke commin out the exhaust?

Make sure that the line on your crank shaft pully is lined up perfectly to your timing belt cover mark. Then take off your AEM cam gear, make your cam gear read 0(TDC), then put it on, make sure that the line with the 0 on it is STRAIGHT UP, just to make sure your camshaft is at TDC, take off your distributer and make sure that the groove at the end of your camshaft is straight up as well(perpendicular to the ground)

well, I took the aem cam gear off, and put the stock cam gear on. I then reset the cam to TDC, the crank to TDC, put the dizzy to TDC, so all that should be all correct, right?

But the 2 and 3 cylinders are not firing. Or so they seem like it. When the motor is running, if I remove the plug from #1 or #4, the motor dies. If I do it with either 2 or 3, nothing changes at all. Not even a drop in idle.

My temp also heats up alot faster than my stock a6.

Yea you should be all good in timing, now you have a problem with spark or fuel...Try this.. test your #2 and #3 plugs, Take one out then have a person crank the car, see if there is spark between the the ends of the plug wires and ground(metal) If there is, your plugs are ok. Next, it must be your fuel, make sure that your #2 and #3 injectors are plugged in right all good(electrical wires).

as for your temp, make sure that you have the coolant topped off, when putting new coolant in the motor, your t-stat is closed and it seems that you topped off the coolant but you didnt because it hasnt flowed through the whole motor yet. Since you had your motor warmed up already, let it cool and top off the coolant level again. If it already is, maybe you have a bad t-stat(prolly opens too late) Is it new?

you DO have the correct firing order yes ?

lookin @ the distributor from the pass side its

3 4
1 2

1&!2 being on the bottom of the dizzy

Yeah, that is all okay.

Here is something else I am going to try after looking at your pic, and this one here:
http://www.automotiveforums.com/vbulletin/attachment.php?s=&postid=783298

I have been trying to set TDC on the cam, with the mark straight up as possible. Since the top mark needs to be at the 11 oclock spot, and the bottom mark, needs to be aligned straight down. Could it be possible the bigger cam is causeing the valves to be open, when they should be closed, causing a spark on a basically dead cylinder? That would also cause it to heat up faster....

RedRacerCivic, yes, I know I have spark on all wires, and plugs. Also, I know how to bleed, and properly fill the coolant system. This is not my first motor I have installed. It's just the first that is fiving me problems like this. :(
