I have a 91 Civic hatch DX. Z6 block Y8 head\intake Gude Stage 1 Cam AEM Cam Gear It's in need of a valve adjustment and I proceeded to start it tonight without yet successfully shutting the little bastards up. Before I go any further, I'm not new to doing valve adjustments, I have been through auto. tech. school (Honda PACT specifically), I've just not been dabbling with cars in about a year now and can't quite remember what I used to know. I have a couple of questions\concerns about my situation and the procedure for it: - The cam gear is advanced 2 degrees, should it be set to zero for a proper valve adjustment? Does the cam like it there or something? - The rocker arms have the slightest amount of up and down play. That bugs the hell out of me cause I'm trying to do something that uses a feeler gauge and needs to be precise. Same goes for the "slight drag" bullshit. Anyway, should the 007. and .009 measurements be taken with the arms at the top of their slack, or at the bottom? If that sounds confusing, imagine the rocker arm hanging over the tip of the valve stem. When you slide the feeler gauge in, it pushes the rocker arm up, there's a little slack there. Now, I've been wondering if I should hold the arm up with a spare finger, measure, and set the adj. screw based on the clearance with the slack of the arm taken out going up, or if I should set the adj. screw based on the clearance of pushing down on the rocker arm and taking and measurement and adjusting. I know this sounds really OCD, but I'm basically thinking this is one of those little things thats not in manuals or classes that you just pick up from years of doing the shit and having done three valve adjustments already and they are still ticking is really getting old. Soo yeah. Oh, one of the three allen bolts on the AEM gear is stripped, any suggestions on how to get that one out?
