hi guys, this is my first time i've even had to ask for help, usually i can find what need in someone elses thread. anyway i hope you can help heres the deal. about 2 months ago i started driving my 240z for the first time, after three weeks the head gasket blows. no big deal right well 5 or 6 weeks later i've finally got everything assembled or so i thought. when i go to start for the first time i get nothing, ignition timing is good,i was pretty damn sure i had the cam aligned correctly but a compression test showed around 100 psi on all six, so thought maybe the cam is off, i've moved it 180 degrees and get no pressure in cyl 1, i moved it back and still 0 psi, i've tried advancing and retarding the cam by a couple teeth on the cam sprocket one tooth at a time and still nothing. One thing i'm hoping to get from you guys is a picture of the cam in the head with cyl 1 TDC with dist rotor at #1. anything else you can chip in with is cool too. thanks
