So all in all I think I did pretty dang good for $200 and the guy helped my pull it all off. I am still debating going back and yanking the whole wiring harness for $60. Engine and Interior. Well I am SUPER excited to get all of this stuff on, but I packed it all into the CRX to wait to be trailer-ed back home to MT before any more work will happen.

Well Cylinder number one has 0 compression.

Cylinder number 2 has this much compression.

If I am correct, the UP ARROWs on each cam gear should point up together correct?!?!

Looks like my cam timing is way effed up.

So the correct way to set cam timing is what????

So the arrows would be rotated slightly counter clockwise from 12 o'clock.

To fix your problem, pull off the upper timing belt cover, set your crank pulley to TDC by lining up the notch with the TDC indication mark on the lower timing belt cover, loosen your timing belt tensioner so that you can slide the belt off the cam gears, then it will just take some patience and a few tries to get the cam gear TDC marks in the center of the two wheels to line up while you ensure the the two "UP" are pointing relatively straight up and both in the same direction. Then, while ensuring the cam gears don't move, reinstall the timing belt starting with the exhaust gear and then the intake gear. Once you think you have it, rotate the engine 2 - 3 cycles to ensure all your TDC marks are lining up properly each time. Rotating the engine counter clockwise will re-apply tension to the belt and you can then re-tighten the tension adjustment bolt.

If you don't know how to do these steps, let me know and i will send you a link to a manual that will show you how to identify the components / procedural steps you need to fix your timing... I hope this helped.
Thanks a ton! I was waiting for someone to say this. I did it yesterday actually, but still no luck...

So I still have low compression which means a bent valve at this point.... Let me know if I am wrong...

So I will pull the head tomorrow most likely.

Well I am back home finally. I called my shop and they said the car should be finished by wednesday... AWESOME!

Oh and I got this little guy in the mail to stop my head from leaking....



So this is how the dash is going to look from now on!


I haz a center console now! With a hole for my stereo! Which will eventually be a mini glovebox for the need info or maybe just a big legit switch panel, idk.



oh and I also now have door panels. They really finish off the car. Looks great. I still have all my aluminum pieces wrapped in plastic which is why they looks messed up.




New lowered seat bracket!



One side needed to be a little higher to be level...


well we pulled out some stuff...


Then we decided to decorate!
