Can you write a how to for checking the lash and adjusting the idle?
I got the valve cover gasket. Are ther any other gaskets or seals that might need to be replaced during install?
Is Drew ever gonna post?
feeler gauges - i'm pretty sure theres a detailed how to somewhere on the website, have a look at andrew's original cams thread thingy...
I reused my valve cover gasket as it was in good shape...no leaks yet so must be ok!
Adjusting the idle....will depend on what management you are running
if you are running the stock ECU, just wind out the idle adjustment screw all the way, then half a turn back in so it doesn't fall out. ECU won't "learn around" it unless your RPM goes over the standard idle speed - if you adjust it higher than the standard idle speed setting it SHOULD bring it back into line with the idle control solenoid over time.
If you are running a microtech or simillar, heres what I did to get the idle working:
Confirm that your ECU is capable of controlling the solenoid, then wire up accordingly.
get someone to sit in the drivers seat for you and get them to turn the car over... it will likely stall....
Wind out the idle adjust screw as detailed above and try again - you might get lucky and land yourself with a really low ratshit idle...but don't be alarmed if it just stalls.
get out your trusty hex bolt keys and adjust the throttle body plate open
give it a full turn, then kick the car over...it should idle, albeit very high.
While car is running, dial the hex bolt back until you have an idle sitting around 800 rpm.
Leave car running, hop in the car and plug in your laptop. Recalibrate the Throttle Position Sensor to 0% (it'll be sitting at something like 2%, because you've opened it that much to get the idle, yo u want to tell your aftermarket management that it is actually the new 0%)
Use the software for your ECU to program the idle control valve to step the idle up to about 900.
In the microtech (can't remember the setting NAMES precisely), but i have the Target RPM set at 900, the minimum opening time at 1ms, maximum opening time at 2ms, cold start adjustment set at 0.4ms (adds more idle control if water temp is below 50C), and the input idle air on the AC compressor set at 0.2ms (adds more idle control if the AC is on).
its not PERFECT - the microtech doesn't like holding such low idle speeds, i don't think the control loop is that sophisticated. I am ATTEMPTING to find a stand alone solution that will accept a tacho signal in and use a more sophisticated control loop (something with an element of fuzzy logic to predict a fall in idle speed earlier) and more inputs so i can get all the accessories "idling up" the motor.
If i cant find something, i'll have a crack at building something.
